                       OVERVIEW OF LASERSIGHT INCORPORATED

   
Operating Segment Information

     LaserSight Incorporated operates in two major operating segments:
technology and health care services. Our technology segment includes LaserSight
Technologies, Inc., LaserSight Patents, Inc. and LaserSight Centers
Incorporated. LaserSight Technologies develops, manufactures and markets
ophthalmic lasers designed to correct common vision disorders. These lasers
utilize a one millimeter scanning laser beam to ablate microscopic layers of
corneal tissue in order to reshape the cornea and to correct the eye's point of
focus in persons with nearsightedness, farsightedness and astigmatism.

     LaserSight Patents licenses various patents related to the use of excimer
lasers to ablate biological tissue. LaserSight Centers is a developmental-stage
company through which we may, in the future, provide laser surgery and other
related eye care surgical services.

     Since December 31, 1997, our health care services segment has consisted of
MRF, Inc. which operates under the name of the Farris Group. The Farris Group
provides health care and vision care consulting services to hospitals, managed
care companies and physicians. Until that date, this segment had also included
MEC Health Care, Inc. and LSI Acquisition, Inc. Under LaserSight's ownership,
MEC was a vision managed care company which managed vision care programs for
health maintenance organizations and other insured enrollees and LSIA was a
physician practice management company which managed the ophthalmic practice
known as the "Northern New Jersey Eye Institute".

Organizational Information

     We were incorporated in Delaware in 1987 but were inactive until 1991. In
April 1993, we acquired LaserSight Centers in a stock-for-stock exchange with
additional shares issued in March 1997 pursuant to an amended purchase
agreement. In February 1994, LaserSight acquired The Farris Group. In July 1994,
we were reorganized as a holding company. In October 1995, we acquired MEC. In
July 1996, our LSIA subsidiary acquired the assets of the Northern New Jersey
Eye Institute. In August of 1997 we formed LaserSight Patents which then
acquired certain patents from International Business Machines Corporation. On
December 30, 1997, we sold MEC and LSIA in a transaction that was effective as
of December 1, 1997. In April 1998, we acquired the assets of the medical
products division of Schwartz Electro-Optics, Inc.
    
Principal Office


     LaserSight's principal office and mailing address are 3300 University
Boulevard, Suite 140, Winter Park, Florida 32792.

                                  RISK FACTORS

   
     In addition to the other information we provide or incorporate by reference
in this Prospectus, you should carefully consider the following risks before
deciding whether to invest in our common stock. In evaluating the risks of
investing in our common stock, you should also evaluate the other information
set forth or incorporated by reference in this Prospectus, including our
financial statements and the notes accompanying them.

INDUSTRY AND COMPETITION RISKS

     WE MAY ENCOUNTER DIFFULTIES COMPETING IN THE HIGHLY COMPETITIVE VISION
CORRECTION INDUSTRY. The vision correction industry is subject to intense,
increasing competition, and there can be no assurance that we will be able to
compete successfully against our current and future competitors. Many of our
competitors have existing products and distribution systems in the marketplace
and are substantially larger, better financed, and better known. Two of our
principal competitors, Summit Technology, Inc. and Autonomous Technology
Corporation, recently entered into a merger agreement. If the proposed merger is
approved by stockholders, it is anticipated that the merger would be completed
during the first quarter of 1999. If completed, the market presence, technology
base and distribution capabilities of the combined entity would be substantial.
Further, the merger would provide Autonomous with licenses to use certain
patents owned by Visx, Inc., the absence of which has been delaying or
preventing the manufacture and sale of its LADARVision System in the United
States.

     OUR COMPETITORS MAY HAVE OR RECEIVE BROADER REGULATORY APPROVALS. A number
of lasers manufactured by other companies have either received, or are much
further advanced in the process of receiving, Food and Drug Administration
approval for specific procedures, and, accordingly, may have or develop a higher
level of acceptance in some markets than our lasers. In addition to laser
systems of Summit, Visx and others already approved for commercial sale in the
U.S., Nidek Co., Ltd. obtained FDA approval of its EC-5000 excimer laser system
in December 1998. Other manufacturers, including Bausch & Lomb, are expected to
obtain approval during 1999, giving them the right to market their systems
commercially in the U.S. We have not yet received the GMP (Good Manufacturing
Practices) clearance from the FDA that is required for the commercial sale of
our LSX laser system. Based on the current status of development efforts, we
believe that it is reasonable to expect such FDA clearance in the next four to
seven months. However, we cannot provide any assurance as to the receipt or the
timing of receipt of such clearance. The established market presence in the U.S.
of previously-approved laser systems, as well as the entry of new competitors
into the market upon receipt of regulatory approvals, could impede our ability
to successfully introduce our LSX system and have a material adverse effect on
our business, financial condition and results of operations.

     NEW PRODUCTS OR TECHNOLOGIES COULD ERODE DEMAND FOR OUR PRODUCTS OR MAKE
THEM OBSOLETE. In addition to competing with eyeglasses, contact lenses and
radial keratotomy, excimer laser vision correction competes or may compete with
newer technologies such as intraocular lenses, corneal rings and surgical
techniques using different types of lasers. To date, we have not been materially
affected by the introduction of new or advanced technologies in the laser vision
correction industry. Two products that may become competitive within the next
one to three years are intraocular lenses and corneal rings. Both of these
procedures involve lens implants that require an invasive surgical procedure,
unlike an excimer laser, and their ultimate market acceptance is unknown at this
time. To the extent that any of these or other new technologies are perceived to
be clinically superior or economically more attractive than excimer laser vision
correction, they could erode demand for our excimer laser products, cause a
reduction in selling prices of such products or render such products obsolete.
In addition, if one or more competing technologies achieve broader market
acceptance or render our PRK and LASIK lasers procedures obsolete, it could have
a material adverse effect on our business, financial condition and results of
operations.

     While we do not anticipate that additional technical difficulties will
arise that would further delay or prevent the successful development,
    


                                       4
<PAGE>

   
introduction and marketing of our A*D*K keratome product, there can be no
assurance that new difficulties will not arise. Unanticipated logistical issues,
such as the manufacturer's failure to meet expected production goals, may arise
which could further delay the commercialization of the product. As is typical in
the case of new and rapidly evolving industries, demand and market for
recently-introduced technology and products is uncertain, and there can be no
assurance that our A*D*K product or future new products and enhancements will be
accepted in the marketplace. In addition, announcements of new products, whether
for sale in the near future or at some later date, may cause customers to defer
purchasing our existing products.
    

     BROAD MARKET ACCEPTANCE OF LASER-BASED EYE TREATMENT IS UNCERTAIN. We
believe that whether we achieve profitability and growth will depend, in part,
upon broad acceptance of PRK or LASIK in the U.S. and other countries. There can
be no assurance that PRK or LASIK will be accepted by either the
ophthalmologists or the public as an alternative to existing methods of treating
refractive vision disorders. The acceptance of PRK and LASIK may be adversely
affected by:

   
         o    The cost of the procedure
         o    Possible concerns relating to safety and efficacy
         o    The public's general resistance to surgery
         o    The effectiveness and lower cost of alternative methods of
              correcting refractive vision disorders
         o    The lack of long-term follow-up data
         o    The possibility of unknown side effects
         o    The lack of third-party reimbursement for the procedures
         o    Possible future unfavorable publicity involving patient outcomes
              from the use of PRK or LASIK systems
         o    The possible shortages of ophthalmologists trained in the
              procedures.

     The failure of PRK or LASIK to achieve broad market acceptance could have a
material adverse effect on our business, financial condition and results of
operations.
    

FINANCIAL AND LIQUIDITY RISKS

   
     WE HAVE EXPERIENCED AND MAY CONTINUE TO EXPERIENCE LOSSES AND OPERATING
CASH FLOW DEFICITS. We experienced significant net losses and deficits in cash
flow from operations for the fiscal years ended December 31, 1996 and 1997 and
for the nine months ended September 30, 1998, as set forth in the following
table. We cannot assure you that we will be able to regain or sustain
profitability or positive operating cash flow.

</TABLE>

   
Although we achieved profitability during 1994 and 1995, we had a deficit in
cash flow from operations of $1.9 million during 1995. In addition, we incurred
losses in 1991 through 1993. As of November 30, 1998, we had an accumulated
deficit of $20.8 million. We expect to report a loss and deficit in cash flow
from operations for the fourth quarter of 1998.
    

                                       5
<PAGE>

   
     WE COULD EXPERIENCE UNANTICIPATED EXPENSES IF OUR UNCOLLECTIBLE RECEIVABLES
EXCEED OUR RESERVES. Although we monitor the status of our receivables and
maintain a reserve for estimated losses, we cannot assure you that our reserves
for estimated losses, which was approximately $1.9 million at September 30,
1998, will be sufficient to cover the amount of our actual write-offs over time.
At September 30, 1998, our trade accounts and notes receivable totaled
approximately $13.6 million, and accrued commissions, the payment of which
generally depends on the collection of such net trade accounts and notes
receivable, totaled approximately $2.1 million. Actual write-offs that
materially exceed amounts reserved could have a material adverse effect on our
consolidated financial condition and results of operations. The amount of any
loss that we may have to recognize in connection with our inability to collect
receivables is principally dependent on our customer's ongoing financial
condition, their ability to generate revenues from our laser systems, and our
ability to obtain and enforce legal judgments against delinquent customers.
Approximately 94% of our net receivables at September 30, 1998 related to
international accounts. Our ability to evaluate the financial condition and
revenue generating ability of our prospective customers located outside of the
United States, and our ability to obtain and enforce legal judgments against
non-U.S. customers, is generally more limited than for our customers located in
the U.S. See "--Company and Business Risks--We are Subject to Risks Associated
with our International Sales."

     WE MAY EXPERIENCE DIFFICULTY COLLECTING RESTRUCTURED RECEIVABLES WITH
EXTENDED PAYMENT TERMS. At September 30, 1998, we had extended the original
payment terms of laser customer accounts totaling approximately $963,000 by
periods ranging from 12 to 60 months. Such restructured receivables represent
approximately seven percent of our net receivables as of that date. Our
liquidity and operating cash flow would be adversely affected if additional
extensions become necessary in the future. In addition, it may be more difficult
to collect laser system receivables if the payment schedule extends beyond the
expected or actual economic life of the system, which we estimate to be
approximately five to seven years. To date, we do not believe any payment
schedules extend beyond the economic life of the applicable systems.

     WE MAY EXPERIENCE LIQUIDITY PROBLEMS AND THERE IS UNCERTAINTY REGARDING THE
TERMS OR AVAILABILITY OF ADDITIONAL CAPITAL. During the eleven months ended
November 30, 1998, we experienced a $12.7 million deficit in cash flow from
operations. We expect that any improvements in cash flow from operations will
depend on, among other things, our ability to market, produce and sell our new
LSX laser systems in larger quantities and our ability to market, produce and
sell our A*D*K product on a commercial basis. During the third quarter of 1998,
LSX laser system sales accounted for the majority of laser systems sold, and we
expect sales of our LSX laser system to make a more significant contribution to
our operating results in the future. Because we are still in the process of
completing the clinical validation of our A*D*K product, we do not believe that
regular commercial shipments of that product will begin until the second quarter
of 1999, although limited shipments may occur in the first quarter.

     We believe that our balances of cash and cash equivalents, together with
our cash flows from operations, should be sufficient to fund our anticipated
working capital requirements through the second quarter of 1999 in accordance
with our current business plan. Our belief regarding future working capital
requirements is based on various factors and assumptions including the
anticipated timely entry into the international marketplace with keratome
related products in the U.S. market with both our keratome related products and
LSX system, the anticipated timely collection of receivables, and the absence of
unanticipated product development costs. These factors and assumptions are
subject to certain contingencies and uncertainties, some of which are beyond our
control. If we do not collect a material portion of current receivables in a
timely manner, experience significant further delays in the shipment of our
A*D*K product or in the FDA clearance and entry into the U.S. market, of our LSX
laser system, or experience less market demand for our products than we
anticipate, our liquidity could be materially and adversely affected.

     In view of our anticipated working capital needs and the uncertainties
associated with the timing of our cash receipts and expenditures, we are
currently seeking additional debt or equity financing to increase our available
working capital. We cannot provide you with any assurance as to the terms,
timing or availability of such financing. We also cannot assure you that we will
not seek additional debt or equity financing in the future to implement our
business plan or any changes thereto in response to future developments or
unanticipated contingences. We currently do not have any commitments for
additional financing. We cannot be certain that additional financing will be
available in the future to the extent required or that, if available, it will be
on acceptable terms. If we
    


                                       6
<PAGE>

   
raise additional funds by issuing equity or convertible debt securities, the
terms of the new securities could have rights, preferences and privileges senior
to those of our common stock. If we raise additional funds through debt
financing, the terms of the debt could require a substantial portion of our cash
flow from operations to be dedicated to the payment of principal and interest
and may render us more vulnerable to competitive pressures and economic
downturns.
    

COMMON STOCK RISKS

   
     THE MARKET PRICE OF OUR COMMON STOCK HAS BEEN VOLATILE. The volatility of
our common stock imposes a greater risk of capital losses on stockholders as
compared to less volatile stocks. In addition, such volatility makes it
difficult to ascribe a stable valuation to a stockholder's holdings of
LaserSight common stock. Factors such as announcements of technological
innovations or new products by LaserSight or its competitors, changes in
domestic or foreign governmental regulations or regulatory approval processes,
developments or disputes relating to patent or proprietary rights, public
concern as to the safety and efficacy of the procedures for which the laser
system is used, and changes in reports and recommendations of security analysts,
have and may continue to have a significant impact on the market price of
LaserSight common stock. Moreover, the possibility exists that the stock market,
and in particular the securities of technology companies such as LaserSight,
could experience extreme price and volume fluctuations unrelated to operating
performance.

     VARIATIONS IN OUR SALES AND OPERATING RESULTS MAY IMPACT OUR STOCK PRICE.
Our operating results have fluctuated in the past, and may continue to fluctuate
in the future, as a result of a variety of factors, many of which are outside of
our control. For example, we have historically operated with little or no
backlog because our products are generally shipped as orders are received, and a
significant portion of orders for a particular quarter have been received and
shipped near the end of the quarter. As a result, our operating results for any
quarter often depend on orders received and laser systems shipped late in that
quarter. Other factors that may cause our operating results to fluctuate
include:

         o    timing of regulatory approvals and the introduction of new
              products;
         o    reductions, cancellations or fulfillment of major orders;
         o    the addition or loss of significant customers;
         o    our relative mix of business;
         o    changes in pricing by us or our competitors;
         o    changes in personnel and employee utilization rates;
         o    costs related to expansion of our business;
         o    increased competition; and
         o    budget decisions by our customers.
    

   
     As a result of these fluctuations, we believe that period-to-period
comparisons of our operating results cannot necessarily be relied upon as
indicators of future performance. In some quarters our operating results may
fall below the expectations of securities analysts and investors due to any of
the factors described above. In such event, the trading price of our common
stock would likely decline.

     THE SIGNIFICANT NUMBER OF SHARES ELIGIBLE FOR FUTURE SALE AND DILUTIVE
STOCK ISSUANCES MAY ADVERSELY EFFECT OUR STOCK PRICE. Sales, or the possibility
of sales, of substantial amounts of our common stock in the public market after
the date of this Prospectus could adversely affect the market price of our
common stock. As of January 29, 1999, substantially all of LaserSight's
13,192,635 shares of common stock outstanding were freely tradable without
restriction or further registration under the Securities Act, except to the
extent such shares are held by "affiliates" of LaserSight as that term is
defined in Rule 144 under the Securities Act or subject only to the satisfaction
of a prospectus delivery requirement.

    


                                       7
<PAGE>

   
        
     Shares of common stock which LaserSight may issue in connection with future
acquisitions or financings or pursuant to outstanding warrants or agreements
could also adversely effect the market price of our common stock and cause
significant dilution in our earnings per share and net book value per share.


         o    We may be required to issue more than 2.2 million additional
              shares of common stock upon the exercise of outstanding warrants
              and to satisfy certain contingent contractual obligations. See
              "Description of Securities -- Warrants and other Agreements to
              Issue Shares."


         o    In addition, the 4 million outstanding shares of Series C and
              Series D Preferred Stock may be converted into common stock at any
              time. See "Description of Securities -- Preferred Stock."
    

         o    The anti-dilution provisions of certain of our existing securities
              and obligations require us to issue additional shares if we issue
              shares of common stock below specified price levels. If a future
              share issuance triggers these adjustments, the beneficiaries of
              such provisions effectively receive some protection from declines
              in the market price of our common stock, while our other
              stockholders incur additional dilution of their ownership
              interest.

   
     We may include similar anti-dilution provisions in securities issued in
connection with future financings. Some of the factors we consider when we
determine whether to include such provisions are our cash resources, the trading
history of our common stock, the negotiating position of the selling party or
the investors, and the extent to which we estimate that the expected benefit
from the acquisition or financing exceeds the expected dilutive effect of the
price-protection provision.

     CERTAIN ANTI-TAKEOVER MEASURES MAY HAVE AN ADVERSE EFFECT ON OUR STOCK
PRICE. Certain provisions of our certificate of incorporation, by-laws and
Delaware law could delay or frustrate the removal of incumbent directors,
discourage potential acquisition proposals and delay, defer or prevent a change
in control of LaserSight, even if such events could be beneficial, in the short
term, to the interests of our stockholders. For example, our certificate of
incorporation allows us to issue preferred stock with rights senior to those of
the common stock without stockholder action. LaserSight also is subject to
provisions of Delaware corporation law that prohibit a publicly-held Delaware
corporation from engaging in a broad range of business combinations with a
person who, together with affiliates and associates, owns 15% or more of the
corporation's common stock (an "interested stockholder") for three years after
the person became an interested stockholder, unless the business combination is
approved in a prescribed manner. We also have adopted a stockholder rights
agreement and declared a dividend distribution of one preferred share purchase
right ("Right") on each outstanding share of common stock. The Rights would
cause substantial dilution to a person or group that attempts to acquire 15% or
more of our common stock on terms not approved by our Board of Directors.
    

COMPANY AND BUSINESS RISKS

   
     WE DEPEND ON OUR KEY PERSONNEL FOR OUR FUTURE SUCCESS. Our ability to
maintain our competitive position depends in part upon the continued
contributions of our executive officers and other key employees, especially
Michael R. Farris, our President and Chief Executive Officer, and J. Richard
Crowley, the President and Chief Operating Officer of our LaserSight
Technologies subsidiary. A loss of one or more such officers or key employees,
especially of Mr. Farris or Mr. Crowley, could have a material adverse effect on
our business. We do not carry "key man" insurance on Mr. Farris, Mr. Crowley or
any other officers or key employees.
    


                                       8

     As we continue the clinical development of our excimer lasers and other
products and prepare for regulatory approvals and other commercialization
activities, we will need to continue to implement and expand our operational,
financial and management resources and controls. While to date we haven't
experienced problems recruiting or retaining the personnel necessary to
implement such actions, there can be no assurance that such problems won't arise
in the future. If we fail to attract and retain qualified individuals for
necessary positions, and if we are unable to effectively manage growth in our
domestic and international operations, it could have a material adverse effect
on our business, financial condition and results of operations.

     PROBLEMS RELATED TO THE "Y2K ISSUE" COULD ADVERSELY AFFECT OUR BUSINESS. As
many computer systems, software programs and other equipment with embedded chips
or processors use only two digits rather than four to define the applicable
year, they may be unable to process accurately certain data, during or after the
year 2000. As a result, LaserSight as well as other business and governmental
entities are at risk for possible miscalculations or systems failures which
could cause material disruptions in business operations. This is commonly known
as the Year 2000 ("Y2K") issue. The Y2K issue concerns not only information
systems and technology used by LaserSight, but also concerns third parties, such
as our customers, vendors and distributors, using information systems and
technology that may interact with or affect our operations.

     We have implemented a Y2K readiness program with the objective of having
all of our significant information systems and technology functioning properly
with respect to Y2K before January 1, 2000. We have developed a comprehensive
plan to assess the actual and potential Y2K impact on our operations, both in
information technology ("IT") areas and non-information technology ("Non-IT")
areas, as well as our product offerings. Our assessment included our
manufacturing and operating systems and the readiness of vendors and other third
parties upon whom we rely.


         o    IT Systems. Our IT systems are microcomputer-based and consist of
              standard software purchased from outside vendors. All software is
              being identified and assessed to determine the extent of
              modification required in order to be Y2K compliant. We believe
              that all software will be made Y2K compliant before the end of
              June 1999 through vendor-provided updates or replacement with
              other Y2K compliant hardware and software. We, as has been planned
              for some time, are also replacing our financial and accounting
              software, and expect to have the majority of such new software
              implemented by the end of March 1999. The vendors of our financial
              and accounting software have represented to us that the software
              is Y2K compliant. Our IT inventory related to Y2K compliance is
              approximately 90% complete, the remediation assessment of problem
              areas is approximately 90% complete, and testing, including
              validation of compliance, is expected to be completed by the end
              of April 1999.

         o    Non-IT Systems. For our Non-IT systems, we have identified third
              parties with which we have a significant relationship that, in the
              event of a Y2K failure, could have a material impact on our
              business, financial condition or results of operations. The third
              parties include utility suppliers, material and supply vendors,
              communication vendors and our significant distributors. Some of
              these relationships, especially those associated with certain
              suppliers, are material to us and a Y2K failure by one or more of
              these parties could have a material adverse effect on our
              business, financial condition and results of operations. We are
              corresponding with these business partners and service providers
              to assess their ability to support our operations with respect to
              each of their Y2K issues. The issues that are identified as part
              of this process are being prioritized in order of significance to
              our operations and we will take corrective action as appropriate.
              We have contacted approximately 98% of our vendors, business
              partners and service providers. Approximately 90% have responded
              to date, and we are continue to assess their responses.

         o    Products. We are not aware of any Y2K problems with our current
              production model, the LSX, as all applicable components and the
              software have been validated and tested. Older models, generally
    


                                       9
            
<PAGE>

   
              manufactured in the first half of 1998 and earlier, may require
              upgraded software and/or hardware. We are taking steps to promptly
              notify affected users and, except for those users under warranty
              or service contract, offer such upgrades at additional cost to the
              user. Such upgrades are currently available and, in addition to
              resolving potential Y2K problems, also provide for more efficient
              system performance.
    

   
     We intend to develop contingency plans for Y2K issues which, if not timely
resolved, could have a significant impact on our operations. These plans will be
designed to minimize the impact of failure to achieve Y2K compliance. Such
contingency plans are expected to be developed by the end of March 1999.

     We estimate the costs to address Y2K issues will total $150,000, of which
approximately $50,000 has been incurred to date. Such costs will be expensed as
incurred, and will exclude the costs of our new financial and accounting
software. Y2K compliance related costs are estimated to be 50% of our total IT
expense budget through the end of 1999. No material IT projects are expected to
be delayed. The costs and time necessary to complete the Y2K modification and
testing processes are based on our best estimates, which were derived utilizing
numerous assumptions of future events including the continued availability of
certain resources, third party modification plans and other factors. Our Y2K
readiness program is an ongoing process and the estimates of costs and
completion dates for various components of the Y2K readiness program described
above are subject to change.

     Due to the general uncertainty inherent in our Y2K compliance, mainly
resulting from our dependence upon the Y2K compliance of the government
agencies, suppliers, vendors and distributors with whom we and our service
providers deal, we are unable to determine at this time our most reasonably
likely worst case scenario. While we expect our Y2K compliance efforts to reduce
significantly our level of uncertainty about the impact of Y2K issues affecting
IT and Non-IT systems and our product offerings, we can not assure you that
costs related to the lack of Y2K compliance of third parties, business
interruptions, litigation and other liabilities related to Y2K issues will not
have a material adverse effect on our business, financial condition and results
of operations.

     GOVERNMENT REGULATION AND REGULATORY DECISIONS MAY ADVERSELY AFFECT OUR
BUSINESS. Our laser products are subject to strict governmental regulations
which materially affect our ability to manufacture and market these products and
directly impact our overall prospects. All laser devices marketed in interstate
commerce are subject to the laser regulations required by the Radiation Control
for Health and Safety Act, as administered by the FDA. The regulations impose
design and performance standards, labeling and reporting requirements, and
submission conditions in advance of marketing for all medical laser products.
Our laser systems produced for medical use require PMA approval by the FDA
before we can ship our laser systems for use in the U.S. Each separate medical
device requires a separate FDA submission, and specific protocols have to be
submitted to the FDA for each claim made for each medical device.

     If and when our laser systems receive PMA approval by the FDA, we will be
required to obtain GMP clearance with respect to our manufacturing facilities.
These regulations impose certain procedural and documentation requirements with
respect to our manufacturing and quality assurance activities. Our facilities
will be subject to inspections by the FDA, and if any noncompliance with GMP
guidelines is noted during facility inspections, the marketing of our laser
products may be adversely affected. In addition, if any of our suppliers of
significant components or sub-assemblies cannot meet our quality requirements,
we could be delayed in producing commercial systems for the U.S. market.

     Additionally, product and procedure labeling and all forms of promotional
activities are subject to examination by the FDA, and current FDA enforcement
policy prohibits the marketing of approved medical devices for unapproved uses.
Noncompliance with these requirements may result in warning letters, fines,
injunctions, recall or seizure of products, suspension of manufacturing, denial
or withdrawal of PMAs, and criminal prosecution.
    


                                       10
<PAGE>

   
     Laser products marketed in foreign countries are often subject to local
laws governing health product development processes which may impose additional
costs for overseas product development. In particular, all member countries of
the European Economic Union ("EU") require CE Mark certification of compliance
with the EU medical directives as the standard for regulatory approval for sale
of laser systems in EU member countries. Both of our LSX and LaserScan 2000
laser systems have received CE Mark certification, the former of which was
received in September 1998.

     We cannot determine the costs or time it will take to complete the approval
process and the related clinical testing for our medical laser products. Future
U.S. legislative or administrative requirements, or elsewhere, may adversely
affect our ability to obtain or retain regulatory approval for our laser
products. The failure to obtain required approvals on a timely basis could have
a material adverse effect on our business, financial condition and results of
operations.

     UNCERTAINTY CONCERNING POSSIBLE PATENT INFRINGEMENT ALLEGATIONS COULD
ADVERSELY EFFECT OUR BUSINESS. There are a number of U.S. and foreign patents
covering methods and apparatus for performing corneal surgery that we do not own
or have the right to use. If we were found to infringe a patent in a particular
market, LaserSight and its customers may be enjoined from making, using and
selling that product in the market and be liable for damages for any past
infringement of such rights. In order to continue using such rights, we would be
required to obtain a license which may require us to make royalty, per procedure
or other fee payments. There can be no assurance that we or our customers will
be successful in securing licenses, or that if we obtain licenses, such licenses
will be on acceptable terms. Alternatively, we might be required to redesign the
infringing aspects of these products. Any redesign efforts that we undertake
could be expensive and might require regulatory review. Furthermore, the
redesign efforts could delay the reintroduction of these products into certain
markets, or may be so significant as to be impractical. If redesign efforts were
impractical, we could be prevented from manufacturing and selling the infringing
products, which would have a material adverse effect on our business, financial
and results of operations.

     While we are not currently involved in any material patent litigation, we
have been the subject of patent infringement allegations in the past and such
allegations are common in our industry. In 1992, Summit and Visx formed a U.S.
partnership, Pillar Point Partners, to pool certain of their patents related to
corneal sculpting technologies. As part of their agreement to dissolve Pillar
Point in June 1998, Summit and Visx granted each other a worldwide, royalty free
cross-license whereby each party will have full rights to license all existing
patents owned by either company relating to laser vision correction for use with
their systems. In connection with our March 1996 settlement of litigation with
Pillar Point regarding alleged infringement by our lasers of certain U.S.
patents, we agreed to notify Pillar Point before we begin manufacturing or
selling our laser systems in the U.S. While we are not contractually obligated
to anyone to obtain a license prior to the selling our lasers in the U.S., one
or more of our competitors may assert that such a license is required. As of the
date of this Prospectus, we have not obtained a U.S. license from either Summit
or Visx, and the terms of any license, if such license is granted, have not been
determined.

     WE ARE REQUIRED TO MAKE PAYMENTS UNDER OUR A*D*K LICENSE AGREEMENT.
In addition to the risk that the A*D*K will not be accepted in the marketplace,
we are required to make certain minimum payments to the licensors under our
A*D*K limited exclusive license agreement. Under the agreement, we are required
to pay a total of $300,000 in two installments due six and 12 months after the
date of our receipt of completed limited production molds and to provide an
excimer laser. We provided the laser during the quarter ended June 30, 1998, and
we expect to accept and receive such molds once we determine that the product is
ready to be commercially shipped. We currently anticipate regular commercial
shipments to commence in the second quarter of 1999, although limited shipments
may occur in the first quarter. In addition, commencing seven months after such
date, we will be required to make royalty payments equal to 50% of our defined
gross profits from A*D*K sales, with a minimum royalty of $400,000 per calendar
quarter for a period of eight quarters.

  WE ARE SUBJECT TO CERTAIN RISKS ASSOCIATED WITH OUR INTERNATIONAL SALES.      
Our international sales accounted for 88% of our total revenues during the nine
month period ended September 30, 1998. We expect sales to international accounts
will continue to represent a comparable percentage of our total sales unless and
until our systems are cleared for commercial distribution in the U.S., or with
respect to those products that do not require regulatory approval, otherwise
enter the U.S. market. The majority of our international sales for the nine
months ended September 30, 1998 were to customers in Canada, China, Brazil,
Mexico, Italy, Argentina, South Africa, and Turkey. Our business, financial
condition and international results of operations may be adversely affected by
present economic instability in Brazil and the impact of that instability on
other South American countries, future economic instability in other countries
in which we have sold or may sell, increases in duty rates, difficulties in
obtaining export licenses, ability to maintain or increase prices, and
competition. In addition, international sales may be limited or disrupted by:


         o    The imposition of government controls
         o    Export license requirements
         o    Political instability
         o    Trade restrictions
         o    Changes in tariffs
         o    Difficulties in staffing and coordinating communications among and
              managing international operations.




     Because all of our sales have been denominated in U.S. dollars, we do not
have exposure to typical foreign currency fluctuation risk. However, due to our
significant export sales, we are subject to currency exchange rate fluctuations
in the U.S. dollar, which could increase the effective price in local currencies
of our products. This could in turn result in reduced sales, longer payment
cycles and greater difficulty in collecting receivables. See "--We Could
Experience Unanticipated Expenses if Our Uncollectible Receivables Exceed our
Reserves" above. Although we have not experienced any material adverse effect on
our operations as a result of such regulatory, political and other factors, such
factors may have a material adverse effect on our operations in the future or
require us to modify our business practices.
    



   
     INADEQUACY OR UNAVAILABILITY OF INSURANCE MAY EXPOSE US TO SUBSTANTIAL
PRODUCT LIABILITY CLAIMS. Our business exposes us to potential product liability
risks that are inherent in the development, testing, manufacture, marketing and
sale of medical devices for human use. We have agreed in the past, and we will
likely agree in the future, to indemnify certain medical institutions and
personnel who conduct and participate in our clinical studies. While we maintain
product liability insurance, we cannot assure you that any such liability will
be covered by our insurance or that damages will not exceed the limits of our
coverage. Even if a claim is covered by insurance, the costs of defending a
product liability, malpractice, negligence or other action, and the assessment
of damages in excess of insurance coverage, could have a material adverse effect
on our business, financial condition and results of operations. Our "claims
made" product liability insurance coverage is limited to $10 million and our
general liability insurance coverage is limited to $6 million, including up to
$5 million of coverage under an excess liability policy. Further, product
liability insurance may not continue to be available, either at existing or
increased levels of coverage, on commercially reasonable terms.
    


   
     WE RELY ON SUPPLIERS FOR CERTAIN CRITICAL COMPONENTS AND SYSTEMS.
LaserSight currently purchases certain components used in the production,
operation and maintenance of its laser systems and related products from a
limited number of suppliers and certain key components are provided by a single
vendor. Any interruption in the supply of critical laser components could have a
material adverse effect on our business, financial condition and results of
operations. For example, the A*D*K product will be manufactured exclusively for
LaserSight by Frantz Medical Development Ltd., an ISO 9001 company experienced
in the manufacture of engineering-grade medical devices. We also have exclusive
supply arrangements for certain key laser system components with TUI
Lasertechnik und Laserintegration GmbH. If any of our key suppliers cease
providing us with products of acceptable quality and quantity in a timely
fashion, we would have to locate and contract with a substitute supplier. We
cannot assure you that such substitute suppliers could be located and qualified
in a timely manner or could provide required products on commercially reasonable
terms.

ACQUISITION RISKS

   
     RISKS ASSOCIATED WITH PAST AND POSSIBLE FUTURE ACQUISITIONS. We have made
several significant acquisitions since 1994, including The Farris Group in 1994,
Photomed in 1997 and 1998, IBM Patents in August 1997 and our acquisition of
certain assets of SEO Medical in April 1998. Although we are currently focusing
on our existing operations, we may in the future selectively pursue strategic
acquisitions of, investments in, or enter into joint ventures or other strategic
alliances with, companies whose business or technology complement our business.
We may not be able to identify suitable candidates to acquire or enter into
joint ventures or other arrangements with or we may not be able to obtain
financing on satisfactory terms for such activities. In addition, with respect
to our recent acquisitions as well as any future transactions, we could have
difficulty assimilating the personnel, technology and operations of the acquired
company, which would prevent us from realizing expected synergies, and may incur
unanticipated liabilities and contingencies. This could disrupt our ongoing
business and distract our management and other resources. We cannot assure you
that we would succeed in overcoming these risks or any other problems in
connection with any acquisitions we may make or joint ventures or arrangements
we may enter into.

     AMORTIZATION AND CHARGES RELATING TO OUR SIGNIFICANT INTANGIBLE ASSETS
COULD ADVERSELY EFFECT OUR STOCK PRICE AND REPORTED NET INCOME OR LOSS. Goodwill
is an intangible asset that represents the difference between the total purchase
price of the acquisitions and the amount of such purchase price allocated to the
fair value of the net assets acquired. Goodwill and other intangible assets are
amortized over a period of time, with the amount amortized in a particular
period constituting a non-cash expense that reduces our net income or increases
our net loss. Of our total assets at September 30, 1998, approximately $16.9
million or 34% were intangible assets. The following table presents an overview
of our significant intangible assets and goodwill at September 30, 1998:
    

<TABLE>
<CAPTION>


                                                            Value of Assets                Amortization Period
                                                       --------------------------       --------------------------
<S>                                                          <C>                               <C>        
Goodwill                                                     $6.7 million                      12-20 years

Cost of Patents                                              $4.5 million                     8 - 17 years

Acquired Licenses and Technology                             $5.7 million                 31 months - 12 years

</TABLE>

   
A reduction in net income  resulting from the amortization of goodwill and other
intangible assets may have an adverse impact upon the market price of our common
stock.  In addition,  in the event of a sale or liquidation of LaserSight or our
assets, there can be no assurance that the value of such intangible assets would
be recovered.

     In accordance with SFAS 121, we review intangible assets for impairment
whenever events or changes in circumstances, including a history of operating or
cash flow losses, indicate that the carrying amount of an asset may not be
recoverable. If we determine that an intangible asset is impaired, a noncash
impairment charge would be recognized. We continue to assess the current results
and future prospects of TFG in view of the substantial reduction in the
subsidiary's operating results in 1996 and 1997. TFG's operating results have
improved in 1998 when compared to 1996 and 1997. If TFG is unsuccessful in
continuing to improve its financial performance, some or all of the carrying
amount of goodwill recorded, $3,790,000 at September 30, 1998, may be subject to
an impairment adjustment.

Common Stock

   
     Holders of LaserSight common stock are entitled to one vote for each share
held on all matters submitted to a vote of stockholders and do not have
cumulative voting rights. Accordingly, holders of a majority of the shares of
common stock entitled to vote in any election of directors may elect all of the
directors standing for election. Holders of common stock are entitled to share
pro rata in such dividends and other distributions as may be declared by the
Board of Directors out of funds legally available for that purpose. Upon the
liquidation or dissolution of LaserSight, the holders of common stock are
entitled to share proportionally in all assets available for distribution to
such holders. Holders of common stock have no preemptive, redemption or
conversion rights. The outstanding shares of common stock issued are fully paid
and nonassessable.

     The transfer agent and registrar for LaserSight common stock is American
Stock Transfer & Trust Company.
    

Preferred Stock

   
     LaserSight's certificate of incorporation authorizes the Board of
Directors, without further stockholder approval, to issue up to an aggregate of
10,000,000 shares of preferred stock in one or more series. The Board of
Directors may fix or alter the designations, preferences, rights and any
qualifications, limitations or restrictions of the shares of each series of
preferred stock, including:

         o    dividend rights
         o    dividend rates
         o    conversion rights
         o    voting rights
         o    terms of redemption
         o    redemption price or prices
         o    liquidation preferences
    

   
The rights, preferences and privileges of holders of common stock may be
adversely affected by, the rights of the holders of shares of any series of
preferred stock which LaserSight may designate and issue in the future.
    


                                       16
<PAGE>

Series A and Series B Preferred Stock

   
     All previously issued and outstanding shares of LaserSight's Series A
Preferred Stock, par value $.001 per share, and Series B Preferred Stock, par
value $.001 per share, have been converted, redeemed or repurchased.
    

Series C Preferred Stock

   
     On June 5, 1998, LaserSight issued 2,000,000 shares of Series C Preferred
Stock. The Series C Preferred Stock is convertible into common stock at the
option of the holders of the Series C Preferred Stock at any time until June 5,
2001. After June 5, 2001, all shares of Series C Preferred Stock then
outstanding will automatically convert into an equal number of shares of common
stock. For a more detailed description of the terms of the Series C Preferred
Stock see LaserSight's Form 8-A/A (Amendment No. 4) filed with the SEC on June
25, 1998.
    

Series D Preferred Stock

   
     On June 12, 1998, LaserSight issued 2,000,000 shares of Series D Preferred
Stock. The Series D Preferred Stock is convertible into common stock at the
option of the holders of the Series D Preferred Stock at any time until June 12,
2001. After June 12, 2001, all shares of Series D Preferred Stock then
outstanding will automatically convert into an equal number of shares of common
stock.

     The holders of the Series D Preferred Stock are entitled to anti-dilution
adjustments if LaserSight issues or sells any shares of common stock, or
securities convertible into or exercisable for common stock, before June 12,
2001 at a price per share, or having a conversion or exercise price per share,
less than $4.00. In the event of such an issuance, the conversion price of the
Series D Preferred Stock will be adjusted in order to allow the Series D
Preferred Stock to convert into that number of shares of common stock which will
maintain the Series D Preferred Stock holders' percentage level of ownership of
LaserSight common stock outstanding as such ownership exists immediately prior
to such below $4.00 per share issuance. This anti-dilution adjustment only
relates to the conversion price of the Series D Preferred Stock that has not
been converted and does not result in adjustments to the number of shares of
common stock, if any, held by the holders of the Series D Preferred Stock. For a
more detailed description of the terms of the Series D Preferred Stock see
LaserSight's Form 8-A/A (Amendment No. 4) filed with the SEC on June 25, 1998.
    

Series E Preferred Stock

   
     The Board of Directors has designated 500,000 shares of Series E Junior
Participating Preferred Stock in connection with the adoption of the
Stockholders Rights Agreement described below. Because of the nature of the
Series E Preferred Stock dividend, liquidation and voting rights, the value of
the one one-thousandth interest in a share of Series E Preferred Stock
purchasable upon exercise of each preferred share purchase right should
approximate the value of one share of common stock. The Series E Preferred Stock
purchasable upon exercise of the preferred share purchase rights will not be
redeemable. Each share of Series E Preferred Stock will be entitled to the
greater of (A) a preferential quarterly dividend payment of $1.00 per share, or
(B) an aggregate dividend of 1,000 times the dividend declared per share of
common stock. In the event of liquidation, the holders of the Series E Preferred
Stock will be entitled to a preferential liquidation payment of $1,000 per
share, plus an amount equal to 1,000 times the aggregate amount to be
distributed per share of common stock. Each share of Series E Preferred Stock
will have 1,000 votes, voting together with the common stock. Finally, in the
event of any merger, consolidation or other transaction in which shares of
common stock are exchanged, each share of Series E Preferred Stock will be
entitled to receive 1,000 times the amount received per share of common stock.

Stockholder Rights Plan
                                  
   
     LaserSight's Board of Directors adopted the Stockholder Rights Agreement in
July 1998 and declared a dividend of one Right on each outstanding share of
common stock. The Rights are payable to stockholders of record as of the close
of business on July 13, 1998 (the "Record Date"). Subject to certain exceptions,
each Right, when exercisable, entitles the holder thereof to purchase from
LaserSight one-thousandth of a share of Series E Preferred Stock of LaserSight
at an exercise price of $20.00 per one-thousandth of a Preferred Share (the
"Purchase Price"), subject to adjustment. The terms of the Rights are set forth
in a Rights Agreement (the "Rights Agreement") between LaserSight and American
Stock Transfer & Trust Company as Rights Agent.

     Until the earlier to occur of (A) 10 days following a public announcement
that a person or group of affiliated or associated persons has become an
"Acquiring Person" (as defined below), or (B) 10 business days, or such later
date as may be determined by action of LaserSight's Board of Directors prior to
such time as any person or group becomes an Acquiring Person, following the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in a person or group
becoming an Acquiring Person (the earlier of such dates being called the
"Distribution Date"), the Rights will be evidenced by common stock certificates.
                 
     Subject to certain exceptions, an "Acquiring Person" is a person or group
of affiliated or associated persons who have acquired beneficial ownership of
15% or more of LaserSight's outstanding common stock. In no event however, will
LaserSight, any subsidiary of LaserSight, or any employee benefit plan of
LaserSight or its subsidiaries be deemed to be an Acquiring Person. In addition,
no person shall become an Acquiring Person as the result of an acquisition of
common stock by LaserSight which increases the proportionate number of shares
beneficially owned by such person and its affiliates and associates to 15% or
more of the common stock then outstanding. However, if such person becomes the
beneficial owner of 15% or more of the common stock then outstanding by reason
of share acquisitions by LaserSight and, after such share acquisitions, (A)
acquires beneficial ownership of an additional number of shares of common stock
which exceeds the lesser of 10,000 shares of common stock or 0.25% of the
then-outstanding common stock, and (B) beneficially owns after such acquisition
15% or more of the aggregate number of common stock then outstanding, then such
person shall be deemed to be an Acquiring Person. Moreover, If LaserSight's
Board of Directors determines in good faith that a person who would otherwise be
an Acquiring Person has become such inadvertently, and such person divests as
promptly as practicable a sufficient number of shares of common stock so that
such person would no longer be an Acquiring Person, then such person shall not
be deemed to be an Acquiring Person for any purposes of the Rights Agreement.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on July 2, 2008, unless the Rights are earlier redeemed or exchanged by
LaserSight, as described below.

     The Purchase Price payable, and the number of shares of Series E Preferred
Stock or other securities or property issuable, upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (A) in the event of
a stock dividend on, or a subdivision, combination or reclassification of, the
Series E Preferred Stock, (B) upon the grant to holders of the Series E
Preferred Stock of certain rights or warrants to subscribe for or purchase
Series E Preferred Stock at a price, or securities convertible into Series E
Preferred Stock with a conversion price, less than the then-current market price
of the Series E Preferred Stock, or (C) upon the distribution to holders of the
Series E Preferred Stock of evidences of indebtedness, assets or capital stock
excluding regular periodic cash dividends paid out of earnings or retained
earnings or dividends payable in shares of Series E Preferred Stock or of
subscription rights or warrants other than those referred to above. With certain
exceptions, no adjustment in the Purchase Price will be required until
cumulative adjustments require an adjustment of at least 1% in such Purchase
Price. LaserSight will not be required to issue fractional shares of common
stock or Series E Preferred Stock other than fractions which are integral
multiples of one-thousandth of a share of Series E Preferred Stock, which may,
at the election of LaserSight, be evidenced by depositary receipts. In lieu of
such issuance of fractional shares, an adjustment in cash may be made based on
    



                                       18
<PAGE>

   
the market price of common stock or Series E Preferred Stock on the last trading
day prior to the date of exercise.

     Subject to certain exceptions described in the Rights Agreement, if any
person or group becomes an Acquiring Person, then each holder of a Right will
have the right to receive upon exercise of such Right that number of common
stock or, in certain circumstances, cash, property or other securities of
LaserSight, having a market value of two times the exercise price of the Right.

     If at any time after the time that any person or group becomes an Acquiring
Person, LaserSight is acquired in a merger or other business combination
transaction or 50% or more of its consolidated assets or earning power are sold,
proper provision will be made so that each holder of a Right, other than Rights
beneficially owned by the Acquiring Person, any Associate or Affiliate thereof,
and certain transferees thereof, which will be void, will thereafter have the
right to receive, upon the exercise thereof at the then-current exercise price
of the Right, that number of shares of common stock of the acquiring company
which at the time of such transaction will have a market value of two times the
exercise price of the Right.

     At any time after the time that any person or group becomes an Acquiring
Person and prior to the acquisition by such person or group of 50% or more of
the outstanding common stock, LaserSight's Board of Directors may exchange the
Rights, subject to certain exceptions, in whole or in part, at an exchange ratio
of one share of common stock or one-thousandth of a share of Series E Preferred
Stock per Right.

     At any time prior to the time that any person becomes an Acquiring Person,
LaserSight's Board of Directors may redeem the Rights in whole, but not in part,
at a price of $.01 per Right, subject to adjustment (the "Redemption Price"),
which may at LaserSight's option be paid in cash, common stock or other
consideration deemed appropriate by the Board of Directors. The redemption of
the Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish;
provided, however, that no redemption will be permitted or required after the
time that any person becomes an Acquiring Person. Immediately upon any
redemption of the Rights, the right to exercise the Rights will terminate and
the only right of the holders of the Rights will be to receive the Redemption
Price.

     The terms of the Rights may be amended by LaserSight's Board of Directors
without the consent of the holders of the Rights, except that from and after
such time as any person becomes an Acquiring Person no such amendment may make
the Rights redeemable if the Rights are not then redeemable in accordance with
the terms of the Rights Agreement or may adversely affect the interests of the
holders of the Rights.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a LaserSight stockholder, including, without limitation, the right to
vote or to receive dividends.

     The Rights will have anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire LaserSight on
terms not approved by LaserSight's Board of Directors.
    

Warrants and Other Agreements to Issue Shares

   
     In connection with the establishment of its credit facility with Foothill
Capital Corporation in April 1997, LaserSight issued warrants to purchase shares
of LaserSight common stock to Foothill. These warrants provide for anti-dilution
adjustments that would be triggered upon certain issuances of LaserSight
securities. In connection with its sale of Series B Preferred Stock in August
1997 and subsequent conversion of such preferred shares into LaserSight common
stock, the sale of the Series C Preferred Stock and the Series D Preferred Stock
such anti-dilution adjustments have resulted in (A) an increase in the number of
Foothill warrants to approximately 583,604, and (B) a reduction to the exercise
price of the Foothill warrants to approximately $5.20 per share. Additional
anti-dilution adjustments to the Foothill warrants could also result from any
future below-market sales of common stock by LaserSight. The Foothill warrants
may be exercised at any time through April 1, 2002.
    


                                       19
<PAGE>

   
     In connection with its sale of the Series B Preferred Stock in August 1997,
LaserSight issued warrants to purchase a total of 750,000 shares of common stock
at a price of $5.91 per share to the former holders of LaserSight's Series B
Preferred Stock. The Series B warrants are exercisable at any time before August
29, 2002. Certain anti-dilution adjustments and other agreements by LaserSight
and the former Series B Preferred Stock holders have resulted in (A) an increase
in the number of Series B warrants to approximately 762,616, and (B) a reduction
to the exercise price of Series B warrants to approximately $2.71 per share. As
of January 29, 1999, 140,625 of such warrants have been exercised. LaserSight is
obligated to maintain the effectiveness of the registration of the Series B
warrant shares under the Securities Act.

     LaserSight also issued warrants to purchase a total of 40,000 shares of
common stock at a price of $5.91 per share to four individuals associated with
the placement agent for the Series B Preferred Stock. These warrants are
exercisable at any time before August 29, 2002. LaserSight's sale of the Series
C Preferred Stock and the Series D Preferred Stock triggered anti-dilution
adjustments which resulted in (i) an increase in the number of warrants to
approximately 40,673, and (ii) a reduction to the exercise price of the warrants
to approximately $5.81 per share.

     Based on previously-reported agreements entered into in 1993 in connection
with our acquisition of LaserSight Centers, and modified in July 1995 and March
1997, LaserSight may be obligated as follows:

         o    To issue up to 600,000 unregistered shares of common stock to the
              former stockholders and option holders of LaserSight Centers.
              These former stockholders and option holders include two trusts
              related to our Chairman of the Board and certain of former
              LaserSight officers and directors. These contingent shares will be
              issued only if we achieve certain pre-tax operating income levels
              through March 2002. Such income levels must be related to our use
              of a fixed or mobile excimer laser to perform certain specified
              types of laser surgery, the arranging for the delivery of certain
              types of laser surgery or receipt of license or royalty fees
              associated with patents held by LaserSight Centers. The contingent
              shares are issuable at the rate of one share per $4.00 of such
              operating income.
    

         o    To pay to a partnership whose partners include our Chairman of the
              Board and certain of our former officers and directors a royalty
              of up to $43 for each eye on which certain specified types of
              laser surgery is performed on a fixed or mobile excimer laser
              system owned or operated by LaserSight Centers or its affiliates.
              This royalty may be paid either in cash or in shares of LaserSight
              common stock

         o    Royalties do not begin to accrue until the earlier of March 2002
              or the delivery of all of the 600,000 contingent shares.

   
     As of January 29, 1999, we have not accrued any obligation to issue
contingent shares or royalty shares. We cannot assure you that any issuance of
contingent shares or royalty shares will be accompanied by an increase in our
per share operating results. We are not obligated to pursue strategies that may
result in the issuance of contingent shares or royalty shares. It may be in the
interest of our Chairman of the Board for us to pursue business strategies that
maximize the issuance of contingent shares and royalty shares.

     If the FDA approves a LaserSight-manufactured laser system for general
commercial use in the treatment of farsightedness that uses part or all of the
know-how of the laser technology we acquired from Photomed, we would be required
to issue to the former Photomed stockholders additional shares of common stock
with a market value of up to $1.0 million. If such approval is not received by
June 1, 1999, this obligation will decrease by approximately $2,740 per day each
day thereafter, and the obligation will be eliminated entirely on June 1, 2000.
As of February 1, 1999, the number of additional shares to be issued would have
been 204,000. Depending on whether and when such FDA approval is received and
the average closing price of LaserSight common stock for the 10-day period
immediately prior to the date of any such approval, the actual number of
additional shares of common stock to be issued could be more or less than this
number.

     In connection with our acquisition of the medical products division of
Schwartz Electro-Optics, Inc. in April 1998, LaserSight agreed to issue up to
223,280 additional shares of common stock if the average of the bid and ask
prices of common stock for the five trading day period immediately prior to
April 15, 1999 is less than $5.00 per share. All 223,280 shares of Common Stock
will be issued unless such price is more than $2.36 per share.

Delaware Law and Certain Charter Provisions

     Certain provisions of LaserSight's certificate of incorporation and
Delaware corporate law described in this section may delay or make more
difficult acquisitions or changes in control of LaserSight that are not approved
by the Board of Directors.

     LaserSight is subject to the provisions of Section 203 of the Delaware
General Corporation Law. Subject to certain exceptions, Section 203 prohibits a
publicly-held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years after the date of
the transaction in which the person became an interested stockholder, unless the
interested stockholder attained such status with the approval of the Board of
Directors or unless the business combination is approved in a prescribed manner.
A "business combination" includes mergers, asset sales and other transactions
resulting in a financial benefit to the interested stockholder which is not
shared pro rata with the other stockholders of the corporation. Subject to
certain exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, 15% or more of
the corporation's voting stock.

     The Delaware General Corporation Law provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's certificate of incorporation or by-laws,
unless a corporation's certificate of incorporation or by-laws, as the case may
be, requires a greater percentage. LaserSight's by-laws may, subject to the
provisions of Delaware General Corporation Law, be amended or repealed by a
majority vote of the Board of Directors.

     LaserSight's certificate of incorporation contains certain provisions that
eliminate a director's liability for monetary damages for a breach of fiduciary
duty, except in certain circumstances involving certain wrongful acts. These
acts include the breach of a director's duty of loyalty or acts or omissions
which involve intentional misconduct or a knowing violation of law. The
certificate of incorporation contains provisions indemnifying the directors and
officers of LaserSight to the fullest extent permitted by the Delaware General
Corporation Law. LaserSight also has a directors and officers liability
insurance policy which provides for indemnification of its directors and
officers against certain liabilities incurred in their capacities as such.
LaserSight believes that these provisions will assist LaserSight in attracting
and retaining qualified individuals to serve as directors.

                              SELLING STOCKHOLDERS


   
     The following table describes the beneficial ownership of LaserSight common
stock by the selling stockholders named in this Prospectus, and the number of
shares of common stock to be offered by the selling stockholders. Unless
otherwise indicated, each person has sole investment and voting power over the
shares listed in the table, subject to community property laws, where
applicable. For purposes of this table, a person or group of persons is deemed
to have "beneficial ownership" of any shares which such person has the right to
acquire within 60 days. For purposes of computing the percentage of outstanding
shares held by each person or group of persons named in the table, any security
which such person or group of persons has the right to acquire within 60 days is
deemed to be outstanding for the purpose of computing the percentage ownership
for such person or persons, but is not deemed to be outstanding for the purpose
of computing the percentage ownership of any other person.

                              PLAN OF DISTRIBUTION

   
     The shares of LaserSight common stock being registered pursuant to this
Prospectus are being registered on behalf of the selling shareholders named in
this Prospectus. All costs, expenses and fees in connection with registration of
the shares offered by this Prospectus will be paid by LaserSight. Brokerage
commissions and similar selling expenses, if any, attributable to the sale of
shares shall be paid by the selling shareholders. The selling shareholders may
sale the shares registered by this Prospectus from time to time in one or more
types of transactions including (A) over-the-counter market transactions, (B)
negotiated transactions, (C) through put or call options transactions relating
to the shares, (D) through short sales of shares, or (E) a combination of such
methods of sale. The shares may be sold at market prices prevailing at the time
of sale, or at negotiated prices. These transactions may or may not involve
securities brokers or dealers. The selling shareholders have advised LaserSight
that they have not entered into any agreements, understandings or arrangements
with any underwriters or broker-dealers regarding the sale of their securities,
nor is there an underwriter or coordinating broker acting in connection with the
proposed sale of shares by the selling shareholders.

     The selling shareholders may sell shares directly to purchasers or to or
through broker-dealers, which may act as agents or principals. These
broker-dealers may receive compensation in the form of discounts, concessions,
    


                                       22
<PAGE>

   
or commissions from the selling shareholders or the purchasers of shares for
whom such broker-dealers may act agents or to whom they sell as principal, or
both. Any such compensation may be equal to, less than or in excess of customary
amounts.

     The selling shareholders named in this Prospectus and any broker-dealers
that act in connection with the sale of shares might be deemed to be
"underwriters" within the meaning of Section 2(11) of the Securities Act, and
any commissions received by such broker-dealers and any profit on the resale of
the shares sold by them while acting as principals might be deemed to be
underwriting discounts or commissions under the Securities Act. Because selling
shareholders may be deemed to be "underwriters" within the meaning of Section
2(11) of the Securities Act, the selling shareholders will be subject to the
prospectus delivery requirements of the Securities Act. LaserSight has informed
the selling shareholders that the anti-manipulative provisions of Regulation M
promulgated under the Exchange Act may apply to their sales in the market.

     Selling shareholders also may resell all or a portion of the shares in open
market transactions in reliance upon Rule 144 under the Securities Act, provided
they meet the criteria and conform to the requirements of such Rule.

     Upon LaserSight being notified by a selling shareholder that any material
arrangement has been entered into with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, a supplement to this
Prospectus will be filed, if required, pursuant to Rule 424(b) under the Act,
disclosing (A) the name of each such selling shareholder and of the
participating broker-dealer(s), (B) the number of shares involved, (C) the price
at which such shares were sold, (D) the commissions paid or discounts or
concessions allowed to such broker-dealer(s), where applicable, (E) that such
broker-dealer(s) did not conduct any investigation to verify the information set
out or incorporated by reference in this Prospectus, and (F) other facts
material to the transaction.

     LaserSight has agreed to indemnify each selling shareholder against certain
liabilities, including liabilities arising under the Securities Act. The selling
shareholders may agree to indemnify any agent, dealer or broker-dealer that
participates in transactions involving sales of the shares against certain
liabilities, including liabilities arising under the Securities Act.

     The foregoing items, except for the SEC registration fee, are estimated.

Item 15.  Indemnification of Directors and Officers

   
     Section 145 of the Delaware General Corporation Law ("DGCL"), inter alia,
empowers a Delaware corporation to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (other than an action by or in the right of the corporation)
by reason of the fact that such person is or was a director, officer, employee
or agent of the corporation or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in or not opposed to the best interests of
the corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. Similar indemnity is
authorized for such persons against expenses (including attorneys' fees) actual
and reasonably incurred in connection with the defense or settlement of any such
threatened, pending or completed action or suit by or in the right of the
corporation if such person acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation, and
provided further that (unless a court of competent jurisdiction otherwise
provides) such person shall not have been adjudged liable to the corporation.
Any such indemnification may be made only as authorized in each specific case
upon a determination by the shareholders or disinterested directors or by
independent legal counsel in a written opinion that indemnification is proper
because the indemnitee has met the applicable standard of conduct. The Charter
provides that directors and officers shall be indemnified as described above in
this paragraph to the fullest extent permitted by the DGCL; provided, however,
that any such person seeking indemnification in connection with a proceeding (or
part thereof) initiated by such person shall be indemnified only if such
proceeding (or part thereof) was authorized by the board of directors of
LaserSight.
    

     Section 145 further authorizes a corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation or enterprise,
against any liability asserted against him and incurred by him in such capacity,
or arising out of his status as such, whether or not the corporation would
otherwise have the power to indemnify him under Section 145.

   
     The Charter provides that, to the fullest extent permitted by the DGCL, no
director of LaserSight shall be personally liable to LaserSight or its
stockholders for monetary damages for breach of fiduciary as a director. Section
102(b)(7) of the DGCL currently provides that such provisions do not eliminate
the liability of a director (i) for a breach of the director's duty of loyalty
to LaserSight or its stockholders, (ii) for acts or omissions not in good faith
    


                                      II-1
<PAGE>

   
or which involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of the DGCL (relating to the declaration of dividends and
purchase or redemption of shares in violation of the DGCL), or (iv) for any
transaction from which the director derived an improper personal benefit.
Reference is made to the Charter and By-laws filed as Exhibits 4.1 and 4.2
hereto, respectively.

     LaserSight maintains directors' and officers' liability insurance policies
covering certain liabilities of persons serving as officers and directors and
providing reimbursement to LaserSight for its indemnification of such persons.
    

Item 16.  Exhibits

     The exhibit index set forth on page II-5 of this Registration Statement is
hereby incorporated herein by reference.

Item 17.  Undertakings.

         (a)  Rule 415 Offering

         The undersigned registrant hereby undertakes:

                (1) To file, during any period in which offers or sales are
       being made, a post-effective amendment to this Registration Statement:

                        (i) To include any prospectus required by Section
         10(a)(3) of the Securities Act of 1933;

                        (ii) To reflect in the prospectus any facts or events
         arising after the effective date of the Registration Statement (or the
         most recent post-effective amendment thereof) which, individually or in
         the aggregate, represent a fundamental change in the information set
         forth in the Registration Statement;

                        (iii) To include any material information with respect
         to the plan of distribution not previously disclosed in the
         Registration Statement or any material change to such information in
         the Registration Statement;

         provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
      the information  required to be included in a post-effective  amendment by
      those  paragraphs is contained in periodic reports filed by the registrant
      pursuant  to Section 13 or 15(d) of the  Securities  Exchange  Act of 1934
      that are incorporated by reference in the Registration Statement.

                (2) That, for the purpose of determining any liability under the
      Securities Act of 1933, each such post-effective amendment shall be deemed
      to be a new registration statement relating to the securities offered
      therein, and the offering of such securities at that time shall be deemed
      to be the initial bona fide offering thereof.

                (3) To remove from registration by means of a post-effective
      amendment any of the securities being registered which remain unsold at
      the termination of the offering.


                                      II-2
<PAGE>

          (b) Filings Incorporating Subsequent Exchange Act Documents by
      Reference

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

          (c) Acceleration of Effectiveness.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

LaserSight Incorporated

Orlando, Florida 32792

Gentlemen:

         We have  acted  as  counsel  to  LaserSight  Incorporated,  a  Delaware
corporation (the "Company"),  in connection with the registration by the Company
under  the  Securities  Act of  1933  (the  "Act")  pursuant  to  the  Company's
Registration  Statement  on  Form  S-3  (File  No.  333-68495)  filed  with  the
Securities and Exchange  Commission (the  "Commission")  on December 7, 1998, as
amended by Amendment No. 1 thereto  filed or to be filed with the  Commission on
or about the date of this letter (as so amended,  the "Registration  Statement")
of an aggregate of up to 1,687,500 shares (the "Shares") of the Company's common
stock, par value $.001 per share (the "Common  Stock"),  issued or issuable from
time to time by the Company as follows:

         (i)      an aggregate of up to 1,500,000 shares (the "Warrant  Shares")
                  issuable upon the exercise of outstanding warrants to purchase
                  Common Stock (such  warrants,  the  "Warrants")  issued by the
                  Company to Meracorp, Inc.; and

         (ii)     an  aggregate of up to 187,500  shares (the  "Kremer  Shares")
                  issued to  Frederic B.  Kremer and  certain  other  parties in
                  connection  with a Letter  Agreement  dated  September 9, 1998
                  between LaserSight and the other parties thereto.

         In connection with this opinion,  we have examined originals or copies,
certified or  otherwise  identified  to our  satisfaction,  of the  Registration
Statement,  the  Certificate  of  Incorporation  of the Company as  currently in
effect, the By-laws of the Company as currently in effect,  various  resolutions
of the Board of  Directors  of the Company,  and such  agreements,  instruments,
certificates of public officials, certificates of officers or representatives of
the Company, the Selling Stockholders (as defined in the Registration Statement)
and others,  and such other documents,  certificates and records,  and have made
such other investigations, as we have deemed necessary or appropriate as a basis
for the opinions set forth herein.

         We  have  assumed  the  legal  capacity  of all  natural  persons,  the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to original documents of all documents submitted to
us as certified or photostatic  copies and the  authenticity of the originals of
such  latter  documents.  In making our  examination  of  documents  executed by

<PAGE>

parties other than the Company, we have assumed that such parties had the power,
corporate and otherwise,  to enter into and perform their respective obligations
thereunder and have also assumed the due  authorization by all requisite action,
corporate and otherwise,  and the execution and delivery by such parties of such
documents and the validity and binding effect thereof.  As to any facts material
to the opinions expressed herein, we have relied upon oral or written statements
and  representations of officers and other  representatives of the Company,  the
Selling Stockholders and others.

         Based upon and subject to the  foregoing,  we are of the opinion  that,
when sold by the Selling  Stockholders  pursuant to the Registration  Statement,
and  provided no stop order shall have been  issued by the  Commission  relating
thereto:

         (i)      the Warrant  Shares,  when issued,  sold and  delivered in the
                  manner and for the consideration  contemplated by the terms of
                  the Warrants and as stated in the  Registration  Statement and
                  any Prospectus  Supplement  relating thereto,  will be validly
                  issued, fully paid and non-assessable; and

         (ii)     the  Kremer  Shares,  when sold and  delivered  in the  manner
                  contemplated by the Registration  Statement and any Prospectus
                  Supplement  relating  thereto,  will be validly issued,  fully
                  paid and non-assessable.

         The opinions set forth above are subject to the qualifications that (a)
enforcement  of the Company's  obligations  under the Warrants may be subject to
(i) bankruptcy, insolvency, reorganization, moratorium or other similar laws now
or hereafter in effect relating to or affecting  creditors' rights generally and
(ii) general  principles of equity  (regardless  of whether such  enforcement is
sought in a  proceeding  at law or in  equity),  and (b) the remedy of  specific
performance and injunctive and other forms of equitable relief may be subject to
equitable  defenses  and to  the  discretion  of  the  court  before  which  any
proceeding therefor may be brought.

         We hereby consent to the filing of this opinion with the Securities and
Exchange  Commission  as  Exhibit  5.1 to the  Registration  Statement.  We also
consent to the  reference to our firm under the caption  "Legal  Matters" in the
prospectus  contained in the Registration  Statement.  We do not, in giving such
consent,  admit that we are  within the  category  of persons  whose  consent is
required under Section 7 of the Securities Act.

                                                       Very truly yours,

                                              /s/ SONNENSCHEIN NATH & ROSENTHAL





                               PURCHASE AGREEMENT
                               ------------------


         THIS AGREEMENT entered into this 9th day of June, 1997, by and between
LASERSIGHT TECHNOLOGIES,  INC. ("LST"), a Florida corporation,  whose address is
12249 Science Drive, Suite 160, Orlando,  FL USA 32826, and TUI LASERTECHNIK UND
LASERINTEGRATION  GmbH, a German corporation,  whose address is Lochhamer Schlog
19, D-82166 Grafelfing/Munchen, Germany ("TUI").

                                   Background

         TUI is in the business of  manufacturing  certain  lasers  and/or laser
components, including an excimer laser, which contains, as a major component, an
excimer licensed technology.

         LST  manufactures  and sells laser  systems  for use in  ophthalmologic
medical  applications,  including  excimer laser  systems for vision  correction
applications.

         TUI  is in the  process  of  developing  a  certain  small  laser  head
technology  ("Laser"),  which  is an  ArF  excimer  laser  as  described  in the
technical  specifications attached hereto as Exhibit 1.4. TUI is willing to sell
the Lasers to LST and to grant LST a limited  license to use the  technology  of
TUI incorporated therein ("Licensed Technology") for use in any and all of LST's
ophthalmic laser systems,  including, but not limited to, LS300, LaserScan 2000,
and LaserScan LSX (the "Systems") on the terms and conditions set forth herein.

                               Terms of Agreement

         IN  CONSIDERATION  of the mutual promises and obligations  contained in
this Agreement, the parties agree as follows:

         1.       LIMITED EXCLUSIVITY.

                  1.1  Exclusive  Purchase  Rights.  During the Term (as defined
herein) of this Agreement, LST shall purchase from TUI and TUI shall sell to LST
on an exclusive  basis,  the Lasers.  TUI hereby grants LST a license to use the
Licensed  Technology  incorporated  in the Laser  according to the terms of this
Agreement.  During  the Term,  as long as LST is not in default  (as  defined in
Article 6), TUI agrees that it will not, for or on behalf of any  competitor  of
LST in the small-beam  scanning laser market in LST's Field of  Application,  as
such term is defined in Exhibit 1.1 attached hereto and  incorporated  herein by
reference,  (i) enter into any agreement to sell, promote,  market or distribute
the  Lasers  or the  Licensed  Technology  or  (ii)  sell,  promote,  market  or
distribute the Lasers or the Licensed Technology.  Notwithstanding the foregoing
rights  of  exclusivity,  if LST  licenses  its  patent  covering  the  Field of
Application to an unaffiliated person or entity, other than by licenses existing
as of the date of this  Agreement,  then TUI shall have the right to sell Lasers
to such persons or entities within the Field of  Application.  LST agrees during
the Term not to  purchase  laserheads  for the  Field  of  Application  from any
supplier  other than TUI,  except that LST may  continue to purchase  laserheads
from MPB without restriction.

                  1.2 Redesign of Licensed Technology.  LST agrees that LST will
not materially  improve or redesign the MPB Technology.  LST does intend to make
process  improvements  in its rework process and to correct certain design flaws
in the areas of optics mounts and electrode  securement.  Such  improvements and
corrections  shall not be deemed to be material  improvements  or redesigns from
the existing  technical state of the Lasers as defined LST's technical  manuals,
copies of which have been provided to TUI.



<PAGE>


                  1.3 Loss of  Exclusive  Purchase  Rights.  TUI shall  have the
right to terminate the exclusive purchase rights of LST if (a) LST does not meet
the minimum  purchase  requirements set forth in Exhibit 3.1 for a period of one
(1) quarter plus a forty-five (45) day cure period, or (b) if LST is past due on
the payment of three (3) or more Laser units for more than  forty-five (45) days
after the due date for  payment for such units.  Termination  will be  effective
immediately upon LST's receipt of notice from TUI. Termination of exclusivity by
TUI upon the  occurrence  of either of the events set forth in this  Section 1.3
shall not  result  in the loss of LST's  rights to  purchase  the  Lasers at the
purchase prices set forth in Article 3.

                  1.4  Non-Circumvention by TUI. The specifications of the Laser
and the Licensed  Technology are set forth in Exhibit 1.4. LST acknowledges that
TUI is  continuously  developing and improving its excimer laser  technology and
that,  as part of this  process,  TUI may improve the Licensed  Technology.  TUI
shall not  circumvent  the  exclusive  rights  granted LST under  Section 1.1 by
making  minor  modifications,  as  defined  in  Exhibit  1.4,  to the design and
specifications  of the Laser, or the Licensed  Technology.  The exclusive rights
granted  LST under  Section  1.1 of this  Agreement  shall not apply to, and TUI
shall not be deemed to have  circumvented  the intent of Section 1.1 as a result
of, a major  modification,  as defined in Exhibit  1.4, to the Laser,  provided,
however,  that TUI agrees to inform LST of any demonstrable major  modification,
as defined in Exhibit  1.4,  to the Laser or the  Licensed  Technology,  and the
technical  improvements and price  influences.  LST shall have the right to have
any such major  modification  incorporated  into future  purchases of the Lasers
under  this  Agreement  at  mutually  agreed  upon  prices  and on terms no less
favorable than those offered to other customers of TUI..

         2.       TERM.

                  2.1 Initial  Term.  The initial term of this  Agreement  shall
begin on the date of Acceptance (as defined below) of the first production Laser
to be delivered by TUI to LST as set forth in Section 3.1 ("Effective Date") and
shall  continue  in full force and effect for a period of  eighteen  (18) months
thereafter ("Initial Term"),  unless otherwise terminated by other provisions of
this Agreement.  "Acceptance" of a Laser means,  after functional testing by LST
in a laser system, the Laser has met all LST-defined technical specifications.

                  2.2  Optional  Renewal  by  LST.  Provided  that  TUI  has not
terminated  pursuant to Section 1.3 LST's exclusive purchase rights as set forth
in  Section  1.1,  LST shall  have the  option to renew  this  Agreement  for an
additional  eighteen (18) months ("Renewal  Term").  The terms and conditions of
purchase  for Lasers for the  Renewal  Term shall be  mutually  agreed to by the
parties,  but the  minimum  purchase  requirements  shall be not  less  than the
minimum purchase requirements,  and no more than one hundred twenty-five percent
(125%) of the minimum purchase requirements, applicable to the Initial Term. For
purposes of this  Agreement,  "Term" shall mean the Initial Term and the Renewal
Term, if any.

         3.       PURCHASE PRICE; TERMS

                  3.1 Purchase Price and Terms. LST shall purchase from TUI, and
TUI shall  sell to TUI,  Lasers  according  to the  specifications  set forth in
Exhibit 1.4,  and for the  purchase  price and on the terms set forth in Exhibit
3.1. TUI must deliver three  prototype  Lasers to LST.  After  Acceptance of all
three prototype Lasers,  LST shall purchase Lasers in the minimum quantities and
for the  purchase  prices  and on the terms set forth in  Exhibit  3.1  attached
hereto and incorporated herein by reference.  The first purchase order by LST is
conditional  on  Acceptance of the three  prototype  Lasers and is made prior to
such  Acceptance  solely for  planning  purposes to enable TUI to obtain  needed
quantities of parties, supplies and equipment.

                  3.2  Delivery,  Testing,  and Payment.  LST shall set forth in
each purchase order sent to TUI the number of units  requested  (which shall not
exceed  thirty (30)  units),  their  requested  delivery  date(s)  and  delivery

<PAGE>

destinations for ordered Lasers, which delivery date will not be less than sixty
(60) days from the date of the purchase  order.  TUI shall  invoice LST for each
order for Lasers  upon  delivery,  as defined in Section  4.1, of such Lasers to
LST.  LST  shall  have the  right to accept  or  reject  any  Laser  based  upon
acceptance testing as described in Exhibit 3.2 ("Product Acceptance"). LST shall
notify TUI in writing of Product  Acceptance or rejection  within  fourteen (14)
days after  delivery.  All invoices  shall be due thirty (30) days after written
notification of Product  Acceptance.  If LST fails to make a required payment to
TUI on or before  ninety  (90) days from the due date,  then TUI shall  have the
right  to  charge  a late  fee on such  amount  at the  rate of 1.5%  per  month
commencing on such ninetieth (90th) day until such invoice is paid in full.

         4.       RISK OF LOSS

                  4.1 TUI's Responsibility.  TUI shall be solely responsible for
the proper  handling,  all risks of physical  damage,  protection from theft and
security of Lasers  prior to delivery of such units to LST. For purposes of this
Agreement,  "delivery" means the time when LST receives  possession of the Laser
from the shipping agent or carrier.

                  4.2 LST's Responsibility.  LST shall be solely responsible for
the proper  handling,  all risks of physical  damage,  protection from theft and
security of Lasers after delivery from TUI.

         5. WARRANTY TUI warrants that Lasers  following  Product  Acceptance by
LST, will be free from defects in materials and  workmanship for a period of one
(1) year after  delivery  to an LST  customer  but no longer than  fifteen  (15)
months  after  the date of  delivery  to LST.  If any  defect  in  materials  or
workmanship appears in any Laser during such period, whether the Laser is in the
control of LST or any  customer  of LST or other  user of a System,  TUI will be
responsible  for the  replacement of the defective  Laser or components  therein
without charge. In order to effect timely warranty repair,  TUI will provide LST
a  limited  number  of  warranty  replacement  Lasers  to be  kept by LST at its
facilities.  Each  defective  Laser  in the  hands  of an LST  customer  will be
replaced  with a  warranty  replacement  Laser and the  defective  Laser will be
returned to TUI, shipping and insurance  prepaid.  After repair of the defective
Laser, TUI will return the Laser to LST shipping and insurance prepaid. LST will
arrange for the shipping of the warranty  replacement  Laser to the customer and
will invoice TUI for the shipping expense.

         Any replacements of optics will be performed in the field by LST or its
trained distributors.  TUI shall provide LST and its designated distributors all
necessary  spare  parts,   inventory,   training,  and  training  materials  for
replacement of optics and optics  alignment.  The spare parts shall be warranted
for a period of ninety (90) days from  installation in the customer's  unit, but
not to exceed  twelve (12) months from  delivery to LST. The  provisions of this
Article 5 shall survive any termination of this Agreement.

         6.       TERMINATION

                  6.1      Termination by TUI.

                          (a)       TUI may terminate only the  exclusivity  set
forth in this  Agreement  if, at the end of any  calendar  quarter,  LST has not
placed with TUI firm purchase  orders for the minimum number of Lasers  required
for such quarter as set forth in Exhibit 3.1, and LST has not cured such default
by placing on or before  forty-five  (45) days into the  immediately  subsequent
quarter  firm  purchase  orders  for the  number of Lasers by which  such  prior
quarter's  purchase  orders  failed to meet the minimum  purchase  requirements,
exclusive of the minimum  purchase  requirements  for such  subsequent  quarter.

                          (b)       TUI  may  terminate  this  Agreement  if LST
fails to pay invoices for any three (3) or more Lasers for more than thirty (30)

<PAGE>

days after the due date, as determined in accordance with Section 3.2,  provided
that TUI has given LST written  notice of such  default and such default has not
been cured within fourteen (14) days after delivery of such notice.

                 6.2      Termination  by LST. LST may terminate  this Agreement
                          as follows:

                          (a)       if TUI fails to  deliver  to LST in a timely
                                    manner the number of Lasers set forth in any
                                    purchase order; or

                          (b)       if more than ten percent (10%) of the Lasers
delivered pursuant to any purchase order are rejected by LST for failure to meet
LST's Product Acceptance testing, provided that LST has given TUI written notice
of such  rejection  and TUI is not able to cure or resolve the  problems  giving
rise to such  rejection,  to the  reasonable  satisfaction  of LST, on or before
thirty (30) days after delivery of such notice.

                  6.3 Effect of Termination.  In the event of any termination of
this  Agreement,  TUI will timely  fulfill all orders placed by LST prior to the
date of notice of termination, if requested by LST.

         7.       CONFIDENTIALITY/PROPRIETARY INFORMATION

                  7.1  Confidentiality.  The  parties  agree  that  any  and all
confidential  and/or  proprietary   information   ("Confidential   Information")
furnished by one party to the other in the course of performing  this  Agreement
shall be and remain the  property of the  disclosing  party.  During the Term of
this  Agreement  and for a period  of three  years  (3)  years  thereafter,  the
recipient of any such Confidential  Information agrees not to reveal,  disclose,
divulge,  sell,  license,  exchange,  lease or in any  other way  transfer  this
Confidential Information to any third party.

                  7.2  Exclusions.  The  provisions  of Paragraph  7.1 shall not
apply to (i) information  that was previously known to the recipient free of any
obligation  to keep it  confidential  as  evidenced  by  written  records,  (ii)
information that is or has been in the public domain, or (iii) information given
to the  recipient  through no fault of the  recipient,  by third persons who are
under no obligation of confidence to the disclosing party.

                  7.3  Remedies  for  Breach.  The parties  agree that  monetary
damages for breach of  obligations  under this Article 7 may not be adequate and
that the non-breaching party shall be entitled to injunctive relief with respect
thereto.

         8.       USE OF TRADEMARKS 

                  8.1 Trademarks.  TUI hereby acknowledges LST's exclusive right
to own and utilize the  tradename or  trademark,  "CeraLase."  TUI may grant LST
permission  to use certain TUI  designated  trademarks,  service marks and other
symbols  ("TUI  Marks")  in  LST's  advertising  and  promotion  of the  Systems
utilizing the Lasers.  LST hereby  acknowledges TUI's ownership of the TUI Marks
and agrees not to assert any rights in the TUI Marks.  The TUI Marks may only be
used by LST and/or  LST  affiliates  to  advertise  and  promote  LST's  Systems
incorporating  the Lasers and not for any other reason.  LST agrees to limit its
use of "CeraLase" to products using the Lasers.

                  8.2 No Other  Rights.  Except as  expressly  provided  in this
Agreement,  nothing  in this  Agreement  shall be  deemed  to grant a party  any
license,  sublicense,  copyright  interest,  proprietary  right or  other  claim
against  or  interest  in  the  other  party's  copyrights,  patents,  or  other
intellectual property, or to that of any unaffiliated third party.

                  8.3 Restrictions on Affiliates.  Except as expressly  provided
in this Agreement, neither party will use, or permit their respective employees,

<PAGE>

affiliates,  agents and  subcontractors  to use, the trademarks,  service marks,
logos,  tradenames or other  proprietary  designations of the other party or the
other party's affiliates, whether registered or unregistered, without such other
party's prior written consent.

         9. ESCROW OF  SPECIFICATIONS.  TUI agrees to provide in written form to

Agreement,   copies   of  the   written   specifications,   designs,   drawings,
manufacturing and assembly  processes and procedures  relating to the Lasers and
the Licensed Technology.  LST agrees to notify TUI of any change of escrow agent
in writing within fifteen (15) days of any change.

                  If TUI  breaches any of its  material  obligations  under this
Agreement,  including,  but not limited to,  non-delivery  of Lasers on time; or
failure of more than 10% of Lasers to pass acceptance testing,  which breach, if
curable,  is not cured within thirty (30) days written notice from LST, then LST
shall have access to the  information  in the escrow  account as a  nonexclusive
licensee for purposes of  manufacturing  Lasers itself or for  contracting  with
another  supplier to  manufacture  the Lasers for a period of one (1) year after
LST or its  other  supplier  has  commenced  manufacturing  using  the  escrowed
information.

                  If TUI is able to  satisfy  LST that TUI is again  capable  of
manufacturing  Lasers in an acceptable  manner and time, then TUI may recommence
the manufacture of Lasers for LST.

         10.  RELATIONSHIP  OF THE PARTIES.  The parties'  relationship  to each
other in the  performance of this Agreement is that of independent  contractors.
Nothing  contained in this Agreement will place the parties in the  relationship
of partners,  joint venturers,  or  employer-employee,  and, except as set forth
herein,  neither  party will have any right to obligate or bind the other in any
manner  whatsoever,  nor to represent to third  parties that it has any right to
enter into any binding obligation on the other's behalf.

         11.  DISPUTE  RESOLUTION;  ARBITRATION.  Any dispute  arising out of or
related to this  Agreement  which  cannot be resolved by  negotiation,  shall be
submitted for amicable  settlement to a neutral third party for  conciliation in
New  York  City.  Requests  for  conciliation  shall  be  made  pursuant  to the
International  Chamber of  Commerce  ("ICC")  Rules for  Optional  Conciliation,
whereunder  the  president  of the ICC shall  appoint a  Conciliation  Committee
consisting  of two  members of the same  nationalities  of the two parties and a
third  member  from a third  country,  who  shall  preside  as  chairman  of the
Committee.  If the conciliation has not been accomplished within sixty (60) days
by way of a settlement of the suit or a basis for  settlement,  the either party
may proceed to arbitration without prejudice.  The parties agree to split evenly
the expenses for conciliation, regardless of the outcome.

         In the event that the dispute has not been  settled by  negotiation  or
conciliation,  the dispute shall be finally  settled by binding  arbitration  in
accordance  with the Rules of  Arbitration  of the ICC by three (3)  arbitrators
appointed in accordance  with this  paragraph.  The decision of the  arbitrators
shall be final and binding on the parties. Venue for all proceedings shall be in
New York City. The costs of arbitration,  including the fees and expenses of the
Arbitrators  and any  administrative  expenses,  shall be shared  equally by the
parties  regardless of the outcome.  Each party shall bear the cost of preparing
and presenting its case. The language of arbitration shall be English.

         The parties each shall,  within twenty (20) business  days,  choose one
arbitrator who shall be independent of the parties to the  arbitration and whose
training,  professional  activity and  nationality are suitable to them. The two
chosen arbitrators shall promptly choose a third arbitrator.  If they are unable
to choose a third  arbitrator  within ten (10) business days after they are both
chosen,  then  the  third  arbitrator  shall  be  chosen  by the  ICC  Court  of
Arbitration.  The  parties  agree  that the  arbitrators  shall have no power or
authority  to make  awards  or issue  orders  of any kind  except  as  expressly
permitted  by this  Agreement,  and in no event shall the  arbitrators  have the
authority to make any award that provides for punitive or exemplary damages. The

<PAGE>

arbitrators'  decision shall follow the plain meaning of the relevant  documents
and shall be final and binding.  The award may be confirmed  and enforced in any
court of competent jurisdiction. All post-award proceedings shall be governed by
the ICC.

         12.      INDEMNIFICATION/LIMITATION OF LIABILITY

                  12.1  Indemnification by LST. LST agrees to indemnify,  defend
and hold  harmless  TUI, its  subsidiaries,  affiliates,  employees,  agents and
assigns from any and all liability to third parties (including,  but not limited
to,  liabilities,  judgments,  damages,  losses,  claims,  costs  and  expenses,
including  reasonable  attorneys'  fees) arising from (i) a breach by LST of its
obligations under this Agreement,  and (ii) the acts,  errors,  representations,
misrepresentations,   or   negligence   of  LST,  its   employees,   affiliates,
distributors or agents.

                  12.2  Indemnification by TUI. TUI agrees to indemnify,  defend
and hold  harmless  LST, its  subsidiaries,  affiliates,  employees,  agents and
assigns from any and all liability to third parties (including,  but not limited
to,  liabilities,  judgments,  damages,  losses,  claims,  costs  and  expenses,
including  reasonable  attorneys'  fees) arising from (i) a breach by TUI of its
obligations under this Agreement,  and (ii) the acts,  errors,  representations,
misrepresentations, or negligence of TUI or its employees.

                  12.3 Limitation of Liability. Neither party shall be liable to
the other for any loss of profit, special,  exemplary,  punitive,  incidental or
consequential  damages that such party,  its employees,  agents or assigns,  may
suffer which are caused by or result from the performance or  nonperformance  of
this Agreement.

         13.  ATTORNEYS'  FEES.  In the event that  either  party is required to
enforce or preserve any of its rights hereunder,  the non-prevailing party shall
pay  all of  the  prevailing  party's  reasonable  attorneys'  fees  and  costs,
including  allocable costs of in-house counsel,  incurred in connection with any
such  action,   post-judgment  collection  proceedings,  and  arbitration  award
proceedings .

         14. FORCE MAJEURE. Neither party shall be deemed to be in default under
this Agreement for any delay or failure to perform resulting from (a) accidents,
fire,  labor  disputes,  acts of nature or other  causes  beyond its  reasonable
control and without its fault or negligence, (b) acts or omissions of the party,
or (c) compliance with any law,  regulation ruling,  order or requirement of any
federal,  state or  municipal  government  or  department  or agency or court of
competent  jurisdiction.  Any delay resulting therefrom shall extend performance
accordingly or excuse performance, in whole or in part, as may be reasonable.

         15. NO  ASSIGNMENT.  This Agreement may not be assigned by any party by
operation of law, or  otherwise,  except with the prior  written  consent of the
other  party,  which  shall  not be  unreasonably  withheld;  provided  that the
exclusivity  rights of LST as set forth in Article 3 shall be  binding  upon any
permitted assignee of TUI.

         16. SEVERABILITY. If any part of this Agreement proves to be invalid or
unenforceable for any reason,  then such invalidity will affect only the portion
of the Agreement  which is invalid.  In all other  respects this  Agreement will
stand as if such invalid or unenforceable provision had not been a part thereof,
and the remainder of the Agreement shall remain in full force and effect.

         17. WAIVER.  Failure on the part of any party to complain of any act or
failure  to  act of  any  other  party  or to  declare  any  party  in  default,
irrespective  of the duration of such failure,  will not  constitute a waiver of
rights hereunder.  No waiver hereunder will be effective unless it is in writing
and executed by the party waiving the breach or default.

                               PRODUCT ACCEPTANCE

         TUI and LST will perform the same product acceptance tests at TUI prior
to  shipment  and  at  LST  (Orlando  or  Costa  Rica)  after  delivery   (Final
Acceptance).

         Each laser will be inspected for completeness of subassemblies,  loose,
missing, or damaged parts.

         Each laser will be tested for functioning  input/output signals and for
functioning electromechanical subassemblies; i.e., gas manifold, fan motor, etc.

         After any  passivation  steps,  each laser must meet minimum  power and
beam  size  requirements  at  specified  repetition  rates.  Exact  methods  and
parameters   are  to  be  determined   with  reference  to  the  detailed  draft
"Requirements for Cera-Tube Mini-Lasers" (February 10, 1997).

         The Laser will be tested in a simulated use test fixture  incorporating
aperture,  power stability  feedback,  focusing lens and beam optics train. Each
laser  must meet  minimal  requirements  for beam size,  energy/pulse,  power at
different  repetition  rates,  and energy  variation over a simulated  treatment
time.  Exact methods and parameters  are to be determined  with reference to the
detailed draft "Requirements for Cera-Tube Mini-Lasers: (February 10, 1997).

         To be financed by June 30, 1997.




                          LICENSE AND ROYALTY AGREEMENT
                          -----------------------------


         This License and Royalty Agreement  ("Agreement"),  is made and entered
into  as  of  this  10th  day  of  September,  1997,  by  and  among  LASERSIGHT
TECHNOLOGIES,  INC., a Delaware corporation ("Licensee"), LUIS A. RUIZ, M.D. and
SERGIO LENCHIG (collectively, "Licensors").

         WHEREAS,  Licensors  are the  owners of the  entire,  right,  title and
interest  in and to a certain  U.S.  letters  patent  and  foreign  patents,  as
identified on Schedule A attached hereto and made a part hereof, pertaining to a
device for use in human corneal refractive surgery (collectively,  the "Licensed
Patents");

         WHEREAS,  Licensors have certain  know-how and  confidential  technical
information  directed  to the  Licensed  Patents  (collectively,  the  "Licensed
Technology");

         WHEREAS,  Licensee desires to acquire a world wide,  limited license to
make,  have made, use or sell the devices  described in or covered by any claims
of the  Licensed  Patents  (the  "Devices")  in those  countries  identified  on
Schedule A (the  "Territory")  and throughout the world,  in accordance with the
terms and conditions provided herein; and

         WHEREAS,  Licensors  are willing to grant such a license to Licensee in
accordance with the terms and conditions provided herein;

         NOW,  THEREFORE,  for and in  consideration  of the mutual promises and
valuable  consideration  set forth herein,  the parties hereto mutually agree as
follows:

         1.       Grant of License.
                 
                  (a) Limited License. Licensors hereby grant to Licensee during
         the Term a  world-wide,  non-exclusive,  terminable,  non-transferable,
         non-sublicensable  (except as  provided  herein)  right and  license to
         make,  have made,  use and sell the Devices under the Licensed  Patents
         and the Licensed  Technology (the "Limited  License").  As used herein,
         the term Licensed  Patents shall include those items listed on Schedule
         A,    and    any    reissues,    divisionals,     continuations,    and
         continuations-in-part.  As used herein, the term Licensed Technology is
         limited to that information known to Licensors as of the Effective Date
         and  specifically  excludes any  information  of  Licensors  concerning
         proprietary software developed or owned by Licensors.

                  (b)  Conversion to Exclusive  License.  Upon the occurrence of
         (i) a ruling by a court of competent jurisdiction, or (ii) a settlement
         or  other  similar   agreement  between  Licensors  and  Chiron  Vision
         Corporation   ("Chiron"),   which  concludes  the  litigation   between

<PAGE>

         Licensors  and Chiron  related to the Licensed  Patents or the Licensed
         Technology (the "Litigation"), and terminates all of Chiron's rights in
         connection  with the  Licensed  Patents  and the  Licensed  Technology,
         Licensors  shall give  notice of such  resolution  to  Licensee.  After
         receiving such notice, Licensee shall have sixty (60) days (the "Notice
         Period") to convert the Limited License (the  "Exclusive  Option") into
         an exclusive license (the "Exclusive  License").  In the event Licensee
         so exercises  the  Exclusive  Option,  the sole effect will be to amend
         Section 1(a) to change the word  "non-exclusive"  to  "exclusive".  All
         other terms and  conditions  of Section 1(a) shall remain in full force
         and effect. At such time (the "Exclusive  Date"),  Licensors  represent
         and warrant that no other party shall have any right, title or interest
         in, to or under the Licensed Patents or the Licensed  Technology.  Upon
         the  conclusion  of the Notice Period and if Licensee does not exercise
         the Exclusive Option, nothing contained in this Agreement shall prevent
         Licensor from granting  additional licenses to the Licensed Patents and
         Licensed Technology.

         2. Term.  This  Agreement  shall be  effective as of the date first set
forth above (the "Effective Date"), and shall commence on the earlier of (i) the
date  Licensee  commences  shipment of the  disposable  microkeratomes,  or (ii)
ninety  (90) days  subsequent  to the date  Licensee  has  received  delivery of
completed  Limited  Production  Molds (as  defined  herein)  (the  "Commencement
Date"),  and  shall  continue   thereafter  for  a  period  of  thirty-one  (31)
consecutive  months (the "Initial Term"),  unless earlier terminated as provided
for herein.  This Agreement  thereafter  shall renew for additional one (1) year
terms (each a "Renewal Term", and collectively  "Renewal Terms", and the Initial
Term together with Renewal Terms shall constitute the "Term") as follows:

                  (a) Resolution of Litigation. If within thirty (30) days prior
         to the termination of the Initial Term or Renewal Term, as the case may
         be, the Litigation  has been resolved in accordance  with Section 1(b),
         and Licensee has exercised the Exclusive  Option,  Licensee  shall have
         the sole  option  to renew  this  Agreement  upon  the same  terms  and
         conditions  set  forth  herein;  provided,  however,  with  respect  to
         Licensee's  obligations  pursuant  to  Section  5  of  this  Agreement,
         Licensee  shall be  obligated to pay to  Licensors,  in addition to the
         compensation described in Section 5(b) which has not been paid, if any,
         only the payments  described in Section  5(a)(v) and Section 5(e),  and
         the amount of such  payments may be adjusted as mutually  agreed by the
         parties.  Should  Licensee fail to exercise the Exclusive  Option,  the
         parties  may  mutually  agree to renew  this  Agreement  upon terms and
         conditions as agreed upon by the parties.

                  (b) Continuing Litigation. If within thirty (30) days prior to
         the  termination  of the Initial Term or Renewal  Term, as the case may
         be, the  Litigation  has not been resolved in  accordance  with Section
         1(b),  Licensee shall have the sole option to renew this Agreement upon
         the terms and conditions as set forth herein;  provided,  however, with
         respect  to  Licensee's  obligations  pursuant  to  Section  5 of  this
         Agreement,  Licensee  shall be obligated  to pay to Licensors  only the
         payments  described in Section 5(a)(v) and Section 5(e), and the amount
         of such payments may be adjusted as mutually agreed by the parties.

         3.       Ownership of Intellectual Property.

                  (a) Licensee acknowledges that Licensors have all right, title

<PAGE>

         and interest in the Licensed Patents and the Licensed  Technology,  and
         that as between  Licensors and Licensee,  Licensors  have the exclusive
         right to use the Licensed Patents and the Licensed  Technology,  except
         as otherwise provided herein. Licensee shall not, at any time, file any
         trademark  or patent  application  with the  United  States  Patent and
         Trademark  Office  or any  other  governmental  entity,  any  copyright
         registration  with  the  U.S.   Copyright  Office  or  with  any  other
         governmental   entity  for  the  Licensed   Patents  and  the  Licensed
         Technology.  Licensee shall not use any of the Licensed Patents and the
         Licensed  Technology  except in  accordance  with this  Agreement.  Any
         patent or  copyright  registration  obtained or applied for anywhere in
         the  world  that  contains  the  Licensed   Patents  and  the  Licensed
         Technology or any substantially similar design, shall be transferred to
         Licensors without compensation.  Notwithstanding  anything set forth in
         this Section 3(a) to the contrary,  the parties  acknowledge  and agree
         that U.S.  Letters Patent No.  5,586,980,  dated December 24, 1996 (the
         "Kremer  Patent"),  is the sole and  exclusive  property of  LaserSight
         Incorporated  ("LaserSight"),  an affiliate  of Licensee,  and that the
         provisions  of this  Section  3(a)  shall  not  apply  to  LaserSight's
         activities in connection with the Kremer Patent.

                  (b) Licensee  shall not oppose or seek to cancel or challenge,
         in any forum,  including,  but not limited to, the United States Patent
         and  Trademark  Office  or  any  other  governmental   authority,   any
         application or  registration  of any trademark,  service mark or patent
         which  contains  the  Licensed  Patents  or  the  Licensed  Technology.
         Licensee shall not oppose or seek to cancel or challenge, in any forum,
         including,   but  not  limited  to,  the  U.S.  Copyright  Office,  any
         application or registration of a design containing the Licensed Patents
         or the Licensed  Technology.  Licensee shall not object to, or file any
         action or lawsuit  because  of, any use by  Licensors  of the  Licensed
         Patents or the  Licensed  Technology,  whether such use is by Licensors
         directly or through different licensees or authorized users unless such
         use conflicts with the terms of this Agreement.

                  (c) Nothing in this Agreement gives Licensee any right, title,
         or interest in any of Licensors' intellectual property except the right
         to use in accordance with the terms of this Agreement.

                  (d)  Licensee   acknowledges   that  all   designs,   artwork,
         compilations or derivatives  ("Works") included in the Licensed Patents
         or the Licensed Technology are the sole property of Licensors. Licensee
         acknowledge  that any Works,  other than  trademarks or service  marks,
         created by it  pursuant to this  Agreement  that  contain the  Licensed
         Patents or the Licensed  Technology are also the property of Licensors.
         Licensee hereby assigns to Licensors any right,  title or interest they
         may have in Works,  other than  trademarks or service marks,  developed
         under this Agreement to Licensors. Licensee warrants they have and will
         maintain  appropriate  agreements  with their employees and independent
         contractors to give effect to this Section. Accordingly, Licensee shall
         not copy, use, assign or otherwise  transfer any rights in any Works or
         any  derivatives  thereof  included,  except  in  accordance  with this
         Agreement.  Licensee  shall not  attempt to obtain or assert  copyright
         rights in any artwork or design,  other than with respect to trademarks
         and service marks, which contains the Licensed Patents and the Licensed
         Technology,  without the express  written  authorization  of Licensors.
         Notwithstanding  anything set forth in this Section  3(d),  the parties

<PAGE>

         acknowledge  and agree that the Kremer Patent is the sole and exclusive
         property of  LaserSight  and that the  provisions  of this Section 3(d)
         shall not  apply to  LaserSight's  activities  in  connection  with the
         Kremer Patent.

                  (e) Licensee  acknowledges  that its  material  breach of this
         Agreement will result in immediate and irreparable damage to Licensors,
         and  that  money  damages  alone  would  be  inadequate  to  compensate
         Licensors.  Therefore,  in the  event  of a  material  breach  of  this
         Agreement by Licensee,  Licensors,  in addition to other remedies,  may
         immediately  obtain  and  enforce  injunctive  relief  prohibiting  the
         material breach or compelling specific performance.

         4. Limitations on the Limited  License.  The Limited License is subject
to the following additional limitations:

                  (a)  Distribution.  In the event Licensee sells or distributes
         the Products  (as defined  herein) to any person,  firm or  corporation
         related in any manner to Licensee or its  officers,  directors or major
         stockholders, or to an exclusive distributor, Licensee shall make Gross
         Profit Payments with respect to such sales or  distribution  based upon
         the Sales Price (as defined  herein)  generally  charged to  Licensee's
         normal distribution network.

                  (b) No Other Use.  Licensee  shall not use the  Products,  the
         Licensed Patents or the Licensed  Technology for any purpose other than
         in connection with this Agreement.

                  (c) Selection of  Manufacturer.  Licensors and Licensee  shall
         mutually agree on the manufacturer of the Products.  Licensee shall (i)
         be responsible  for the cost of the  manufacture of the Products,  (ii)
         shall enter into contracts for the manufacture of the Device, and (iii)
         be  responsible  for the purchase of those items  identified in Section
         5(c)(iii) which are necessary to complete the Product.

                  (d) Premium Rights.  Licensee shall not manufacture,  sell, or
         distribute the Products as Premiums,  for publicity purposes,  for fund
         raising,  as giveaways,  in  combination  sales,  or for disposal under
         similar methods of merchandising except as provided in this subsection;
         provided, however, during the first two (2) calendar quarters following
         the Commencement Date,  Licensee shall have the right to grant Premiums
         in an amount not to exceed five  percent  (5%) of the total  disposable
         microkeratomes  produced during the applicable  calendar  quarter,  and
         such  amount  will be reduced  to one  percent  (1%) for each  calendar
         quarter thereafter. For purposes of this Agreement,  "Premium" shall be
         defined  as any  time  the  Products  are  sold or  given  away for the
         purposes of increasing the sale,  promoting,  or publicizing  any other
         product,  service  or  establishment,  including  incentives  for sales
         force, trade or consumer promotions.

                  (e)  Notices.  Licensee  shall  stamp on the  Products  or any
         packaging  for the  Products  such  intellectual  property  notices  as
         reasonably directed from time to time by Licensors.
<PAGE>

                  (f) Quality Control.  All of the Products,  with the exception
         of  those  items  described  in  subsection  5(c)(iii)(H),  (I) and (L)
         (collectively,  the "Excluded  Items"),  manufactured  pursuant to this
         Agreement  shall be  manufactured  and produced in accordance  with the
         specifications developed and provided to Licensee by Licensors.

         5.       Consideration.

                  (a)  Limited  License.   As  consideration   for  the  Limited

                                    provide   Licensors   with   the   necessary
                                    equipment and supplies to upgrade  Licensors

                                    shall be paid to  Licensors  no  later  than

                                    (i) by a court, or (ii) in connection with a
                                    settlement  agreement,  within the Territory
                                    that  determines  that the  Devices  sold by
                                    Licensee infringe the intellectual  property
                                    rights of a third party not affiliated  with
                                    Licensee or resolves  any such  dispute,  as
                                    applicable,  and (C) distribution  discounts
                                    and sales  commissions  associated  with the
                                    Products; provided, however, for purposes of
                                    this calculation  distribution discounts and
                                    sales  commissions  shall not  exceed 35% of
                                    gross sales,  shall be  subtracted  from the
                                    total  invoiced  amounts of all sales of the
                                    Products,   less  any  credits  for  returns
                                    actually   made  and   supported  by  credit
                                    memoranda issued to the customer (the "Sales
                                    Price");

                           (ii)     any    rebates    and    commissions    from
                                    manufacturers, distributors or other sources
                                    shall  be  deducted  from  the Cost of Goods
                                    Sold;

                           (iii)    for purposes of  determining  Gross  Profit,
                                    all amounts  invoiced  by Licensee  shall be
                                    included  which are the result of Licensee's
                                    sale  of  the  Devices  and  other   related
                                    components  including,  but not  limited to,
                                    (A) disposable  microkeratome with gear box,
                                    suction ring and suction handle,  (B) motor,
                                    (C) motor power  cord,  (D)  tonometer,  (E)
                                    suction and power  supply,  (F) foot switch,
                                    (G) tubing,  (H) user's manual,  (I) sterile
                                    packaging, (J) control consoles, (K) blades,
                                    (L) replacement parts, (M) lid speculum, and
                                    other component parts which are manufactured
                                    utilizing  the Licensed  Patents  and/or the
                                    Licensed   Technology   (collectively,   the
                                    "Products").

                  (d) Cost of Goods Sold. "Cost of Goods Sold" shall include (i)
         the  manufacturing  costs  from an OEM  vendor  of the  Products,  (ii)
         packaging costs associated with the manufacture and distribution of the
         Products,  (iii) sterilization costs associated with the Products,  and
         (iv) shipping costs associated with the Products.

                  (e) Minimum  Gross  Profit  Payments.  Commencing  on the date
         which is seven (7) months  after the  Commencement  Date (the  "Minimum
         Gross Profit Date"),  and  continuing  through the balance of the Term,
         the quarterly  Gross Profit  Payments which will be paid by Licensee to

<PAGE>

         Licensors  during each calendar  quarter shall equal or exceed $400,000
         U.S., and after the Exclusive Date this quarterly amount shall increase
         to  $600,000  U.S.  (each a "Minimum  Payment  Requirement").  Licensee
         acknowledges  that  Minimum  Payment  Requirements  are a floor for the
         Gross Profit Payments and Licensee shall use its best efforts to ensure
         the Gross  Profit  Payments  exceed the Minimum  Payment  Requirements.
         Notwithstanding anything set forth herein to the contrary, each Minimum
         Payment  Requirement shall be adjusted as follows (the "Minimum Payment
         Requirement Adjustment"):

                           (i) if the  Minimum  Gross  Profit Date occurs in any
                           month  other  than  January,   the  Minimum   Payment
                           Requirement  for the  calendar  quarter  in which the
                           Minimum  Gross Profit Date occurs shall be reduced to
                           the amount  resulting from multiplying the applicable
                           Minimum Payment  Requirement,  times a fraction,  the
                           numerator  of which  shall be the  number  of  months
                           remaining in the calendar  quarter in which the Gross
                           Profit  Payment Date occurs,  and the  denominator of
                           which shall be four (4) months. A related  adjustment
                           shall be made to the Minimum Payment  Requirement for
                           the  calendar  quarter  during  which this  Agreement
                           terminates  whereby the Minimum  Payment  Requirement
                           then  in  effect  shall  be  reduced  to  the  amount
                           resulting  from   multiplying  such  Minimum  Payment
                           Requirement, times a fraction, the numerator of which
                           shall be the difference  between the number of months
                           remaining in the calendar  quarter in which the Gross
                           Profit  Payment  Date falls and four (4) months,  and
                           the  denominator  of which  shall be four (4) months;
                           and

                           (ii) if at any time during the Term, (A) a royalty is
                           imposed in connection with the sale of the Device, or
                           (B) an  injunction  is issued by a court of competent
                           jurisdiction   whereby  Licensee  is  prevented  from
                           distributing the Products or any other dispute arises
                           in  connection  with  the  Licensed  Patents  or  the
                           Licensed   Technology   (collectively,    a   "Patent
                           Dispute"),  the Minimum Payment  Requirement  then in
                           effect shall be reduced to the amount  resulting from
                           multiplying  such Minimum Payment  Requirement  times
                           eighty  percent  (80%).  Any  such  adjustment  shall
                           remain  in  effect  until  such  time  as the  Patent
                           Dispute is finally resolved in a manner acceptable to
                           Licensee  or the  royalty  is no  longer  imposed  in
                           connection  with the sale of the Device,  as the case
                           may be. If the Minimum Payment Requirement is reduced
                           as result of a Patent  Dispute such  reduction  shall
                           only   affect  the   Minimum   Payment   Requirements
                           prospectively.  If the  duration of any such event or
                           events  described above is less than a calendar year,
                           any such  adjustment  shall be pro-rated based on the
                           number  of  months   during   which   such  event  is
                           continuing.

                  (f)  Minimum  Gross  Profit  Payment  Reconciliation.   Within
                  forty-five  (45) days after the end of each  calendar  quarter
                  after the Minimum Gross Profit Date,  Licensee shall calculate
                  the Minimum Gross Profit Payment  shortfall (the "Gross Profit

<PAGE>

                  Payment  Shortfall") by  subtracting  (i) the aggregate of all
                  quarterly Gross Profit  Payments made to Licensors  during the
                  immediately  preceding calendar quarter, from (ii) the Minimum
                  Payment  Requirement  then in effect as reduced by the Minimum
                  Payment Requirement  Adjustments,  if any. If the Gross Profit
                  Payment  Shortfall is a positive number no further action will
                  be  necessary.  If the Gross  Profit  Payment  Shortfall  is a
                  negative number, then Licensee agrees to pay the amount of the
                  Gross Profit  Payment  Shortfall  in cash to Licensors  within
                  forty-five (45) days after the end of the applicable  calendar
                  quarter;  provided,  however, if in any prior calendar quarter
                  Gross  Profit  Payments  have  exceeded  the  Minimum  Payment
                  Requirement for the applicable calendar quarter ("Excess Gross
                  Profit  Payment"),  Licensee  shall be entitled to offset such
                  Gross  Profit  Payment  Shortfall  by a draw down  against the
                  aggregate of all Excess Gross Profit  Payments which have been
                  previously  paid to Licensors  by Licensee  during the current
                  calendar year and not previously drawn against, if any.

         6.       Statement, Payments and Penalties.

                  (a) No later than  forty-five  (45) days  after each  calendar
         quarter ending in March, June,  September and December,  Licensee shall
         submit to  Licensors  full and accurate  statements  (each a "Quarterly
         Statement") showing the quantity,  description,  Cost of the Goods, and
         Gross  Profits  of the  Products  distributed  and/or  sold  during the
         preceding  months,  including any  additional  information  kept in the
         normal course of business by Licensee which is appropriate to enable an
         independent  determination  of the amount due hereunder with respect to
         the  Products.  All  Gross  Profit  Payments  then  due  shall  be made
         simultaneously  with  the  submission  of  each  Quarterly   Statement.
         Quarterly Statements shall be submitted whether or not they reflect any
         sales or whether any Gross Profit Payments need to be made.

                  (b) Failure to submit timely or accurate Quarterly  Statements
         and/or Gross Profit Payments shall result in an additional charge of 1%
         per month on any balance unpaid as of the applicable  reporting  period
         or the maximum allowed by applicable law, whichever is lower.

                  (c)  The  receipt  and/or   acceptance  by  Licensors  of  the
         Quarterly  Statements  or Gross Profit  Payments,  or any payments paid
         hereunder,   shall  not  preclude   Licensors  from   questioning   the
         correctness  thereof. In the event that any inconsistencies or mistakes
         are  discovered  in  Quarterly  Statements  or  payments,   they  shall
         immediately be rectified by Licensee and the appropriate  payment shall
         be made by Licensee.

                  (d) Licensee shall,  unless  otherwise  directed in writing by
         Licensors,  send all Gross Profit Payments by wire transfer as directed
         by  Licensors,  and shall send all  statements to Licensors by mail and
         facsimile  transmission with delivery confirmed to the addressee at the
         addresses set out in Section 25.

         7.       Records and Right to Audit.
<PAGE>

                  (a)  Licensee  each shall keep,  maintain  and preserve in its
         principal place of business during the Term, any renewal periods and at
         least five (5) years following termination or expiration,  complete and
         accurate  books,  accounts,  records and other  materials  covering all
         transactions  related  to this  Agreement  in a  manner  such  that the
         information contained in the statements referred to in Section 6 can be
         readily determined  including,  without  limitation,  customer records,
         invoices,  correspondence  and banking,  financial and other records in
         Licensee's possession or under its control.  Licensors may designate an
         independent  auditor  or  auditors  and  such  independent  auditor  or
         auditors  shall  have the right to  inspect  and  audit  all  materials
         related to this Agreement,  subject to the confidentiality requirements
         set forth in Section 23.

                  (b) Such materials shall be available for inspection and audit
         (including  photocopying) at any time during (i) the Term, and (ii) the
         period six (6) months  immediately  following  Licensors receipt of its
         final payment due hereunder in the event of  termination or expiration;
         however,  such inspection or audit shall not occur more often than once
         every twelve (12) months  during the Term,  and shall take place during
         reasonable  business  hours and upon at least  five (5) days  notice by
         Licensors  and/or their  representatives.  Licensee will  cooperate and
         will not cause or permit any  interference  with Licensors and/or their
         representatives  in the  performance  of their duties of inspection and
         audit.  Licensors,  and/or their  representatives,  shall have free and
         full access to said materials for inspection and audit purposes.

                  (c) Should any audit indicate an  underpayment of five percent
         (5%) or more of the Gross Profit  Payments due Licensors for the period
         since  (i) the  Commencement  Date,  or (ii)  date of the  last  audit,
         whichever is later,  the reasonable  cost of the audit shall be paid by
         Licensee.  Should any audit  indicate  an  underpayment  of ten percent
         (10%) or more, during the same period,  Licensee shall pay Licensors an
         additional fee equal to ten percent (10%) of the underpayment.  Payment
         of the audit cost and any  additional  fees is in  addition to the full
         amount of any underpayment,  including  interest as provided in Section
         6(b),  shall be paid by Licensee if the results of such audit  indicate
         an underpayment  of ten percent (10%) or more.  Licensee shall cure any
         contract breaches discovered during the audit,  provide amended reports
         if  required,  and  submit  the  amount of any  underpayment  including
         interest,  additional  fees and, if  applicable,  the cost of the audit
         within sixty (60) days from the date of the delivery to Licensee of the
         results of the audit.

         8. Disclosure of Licensed Patents/Licensed  Technology.  Upon execution
of this Agreement, Licensors shall promptly disclose to Licensee all information
it  possesses  relating to the  Licensed  Patents and the  Licensed  Technology.
Licensors  shall  continue  to  provide  any  technical  assistance   reasonably
requested by Licensee from time to time during the Term.

         9.  Maintenance  of Patents.  Licensors  shall be  responsible  for all
payments, including, without limitation,  payments of maintenance fees, required
to keep the Licensed Patents in force for their full terms.
<PAGE>

         10. Additional  Filings;  Approvals.  If Licensee (i) desires to market
the  Products  in any country  where  regulatory  approval  is required  but not
granted as of the  Effective  Date,  (ii)  desires to obtain  patent  protection
relating  to  any  further  discoveries,   inventions,   technology,   know-how,
enhancements,  improvements, modifications or other developments relating to the
Licensed  Patents or the Licensed  Technology  in any country  where such patent
protection may be granted and has not been granted as of the Effective  Date, or
(iii) is required to file with any  governmental or other  licensing  agency any
form or application related to the Products,  including without limitation,  the
filings or applications  described in Section 22(a), Licensors shall provide all
assistance  reasonably  necessary to enable  Licensee to obtain such  regulatory
approval, licensing approval or patent protection, as the case may be. The costs
of obtaining  all  relevant  approvals  or  protection  shall be borne solely by
Licensee.

         11.      Patent Litigation.

                  (a) Infringement of the Licensed  Technology.  Should Licensee
                  or  Licensors  learn  of any  infringements  of  the  Licensed
                  Patents or the Licensed  Technology or any part thereof by any
                  third party, they or it shall promptly notify the other party.
                  If Licensee has not exercised the Exclusive Option,  Licensors
                  shall  have the sole  right but not the  obligation  to pursue
                  such   infringements.   Should   Licensors   pursue   such  an
                  infringement,  Licensee will  cooperate  therein as reasonably
                  requested by Licensors. If any monetary settlement or judgment
                  is  obtained  as a  result  of a suit  for  infringement,  the
                  proceeds obtained shall be the sole property of Licensors.

                           If Licensee has exercised  the  Exclusive  Option and
                  Licensors decline to pursue such an infringement, Licensee may
                  institute and prosecute suits for infringement in its own name
                  and at its own  expense,  and  Licensors  will join as parties
                  plaintiff in such suits and  cooperate  therein as  reasonably
                  requested by Licensee.  If any monetary settlement or judgment
                  is  obtained  as a  result  of a suit  for  infringement,  the
                  proceeds obtained shall be applied first to recover Licensors'
                  and Licensee's reasonable expenses in proportion to the amount
                  each expended in such suit,  and any excess  proceeds shall be
                  equally divided between Licensee and Licensors.

                  (b) Defense of Licensed Technology.  With the exception of the
                  Litigation,  should any  litigation  by a third party  against
                  Licensee  alleging  that the  manufacture,  use or sale of the
                  Devices  infringes any patent or rights under a patent of such
                  third party arise, Licensee shall promptly notify Licensors of
                  such litigation, and Licensors shall defend and/or settle such
                  litigation at their sole cost and expense;  provided  however,

                                    of this Agreement.

                  (a) Other  Rights/Remedies.  Any termination of this Agreement
         will be without  prejudice  to the rights and  remedies of either party

         other  products   utilizing  the  Licensed   Patents  or  the  Licensed
         Technology,  but may continue to distribute its remaining  inventory of
         Products in existence at the time of  expiration or  termination  for a
         period of ninety (90) days,  provided all statements  (including  Final

         the disposal period Licensee deliver all statements and payments due in
         accordance  with  Sections  6 and  comply  with  all  other  terms  and
         conditions  of this  Agreement.  Licensors  shall  have the  option for
         thirty (30) days (the "Option Period"), to purchase all remaining stock
         after  said  ninety  (90)  day  period  at a price  which  shall  equal

         statement  shall be furnished  within  thirty (30) days after notice of
         termination.  Licensors  shall  have  the  right  to  conduct  physical

a violation of this Section 17.

         18. Mold Use and Manufacture.  The Molds are the exclusive  property of
Licensors  which Licensee is permitted to use during the Term of this Agreement.

molds  ("Limited  Production  Molds"),  each  capable  of  producing  disposable
microkeratomes   which  are  safe  and   effective   for  their   intended   use
(collectively,  the  "Molds").  Licensors  shall be solely  responsible  for the
payment  of  all  costs  incurred  to  complete  product  design,   manufacture,
engineering and testing of the Molds; provided,  however, Licensors and Licensee
shall share equally in the cost of manufacturing  the Limited  Production Molds.
Licensee will make no other molds to manufacture disposable  microkeratomes.  In
the event the Molds  need to be  replaced,  as  determined  by the  manufacturer

         20. Payment of Taxes.  Licensors represent that they are not subject to

imposed and  Licensee is required by law to withhold it,  Licensee  shall notify
Licensors  in  order  to  allow  Licensors  to  contest  such  imposition.   All
consideration  paid to Licensors  pursuant to this Agreement shall not take into
account any national,  federal,  state, province,  municipal or other government
excise, sales, use, occupational or like taxes, duties, customs or penalties now
in force  or  enacted  in the  future  (collectively,  a  "Tax").  If any Tax is
imposed, Licensors shall be responsible for the payment of such Tax. If Licensee
is required by law,  rule or regulation to pay or withhold any Tax in connection
with any consideration  paid to Licensors  pursuant to this Agreement,  Licensee
shall be entitled to reduce the applicable  Minimum  Payment  Requirement by the
amount of any such Tax paid or withheld by Licensee during the applicable  year.
The  parties  agree to use  reasonable  efforts  to pursue  any  certificate  of
exemption  or  similar  document  or  proceeding  if  advised  by  counsel  that
consideration  paid to Licensors pursuant to this Agreement may be exempted from
any Tax.

         21. Product  Liability.  Licensee agrees to indemnify,  defend and hold
Licensors  their  successors  and assigns  harmless from and against any and all
liability,  loss, damage, cost or expense (including  reasonable attorneys' fees

damage  based on the use,  manufacture  or sale (other  than  claims  arising in
connection with the design, engineering and/or the specifications of the Devices
delivered  pursuant to Section  4(f)) of the Products  manufactured  and sold by
Licensee,  their subsidiary,  affiliated and controlled companies.  At all times
during the Term, Licensee shall procure and maintain product liability insurance
coverage  related to the Products sold pursuant to this  Agreement in the amount
of $2 million per year in the aggregate.  Licensee  shall cause  Licensors to be
named as  additional  insureds  under any such  insurance  policy.  Evidence  of

Licensors acknowledge and agree that Licensee would incur substantial damages in
the event Licensee reasonably determines that Licensors have not satisfied their
obligations  set forth in  Section  18 and/or  this  Section  22,  and that such
damages would be difficult to calculate. Licensors further acknowledge and agree
that  all  amounts  of money  paid and all  other  property  previously  paid or
delivered  to  Licensors  by Licensee  is a  reasonable  estimate of  Licensee's
damages in the event of default by Licensors  pursuant to Section 18 and/or this
Section 22.

         23.  Confidentiality.  Both  during  and after  the  Term,  none of the
parties shall in any manner, directly or indirectly,  disclose or divulge to any
person or entity (other than such party's employees,  agents or consultants) any
information  related to the Licensed Patents,  the Licensed  Technology or other
confidential and proprietary trade secret information disclosed to them pursuant
to this Agreement;  provided,  that such  confidentiality  obligations  will not
apply to (a) matters of public  knowledge in the industry;  (b) matters known or
disclosed to any party under no  obligation  of  confidentiality  either  before
entering  this  Agreement or  thereafter;  (c) matters  which are required to be
disclosed or divulged by law; and (d) matters which the parties hereto  mutually
agree in writing to disclose.

         24. Force Majeure. Neither party shall be liable for failure to perform
hereunder  if such  failure  is  occasioned  by any cause  beyond  such  party's
control, including,  without limitation, war or civil disturbance,  fire, flood,
accident,  explosion,  interruption  of  transportation,  embargo,  inability to
procure or  shortage of  materials  or  equipment,  interruption  of  production
facilities, governmental order or regulation (including, without limitation, the
FDA), or labor dispute.  Suspension of a party's  performance for any such cause
shall be  limited to the  period of time  during  which such cause is in effect,
plus a reasonable time thereafter.  Such suspension shall not affect the running
of the Term and shall not be regarded as a breach of this Agreement.

         25. Notice.  Every notice,  request,  demand,  and other  communication
contemplated  by this Agreement shall be in writing and deemed to have been made
either when personally delivered to the respective party, or three days after it

         26.  Waiver.  Neither  waiver by either  party of any breach or default
under this  Agreement  by the other  party,  nor the failure of either  party to

                             MANUFACTURING AGREEMENT
                             -----------------------


         Agreement made as of the 10th day of September, 1997 between LaserSight
Technologies,  Inc.  ("LaserSight"),  a  Delaware  corporation  (a wholly  owned
subsidiary  of  LaserSight  Incorporated,  a Delaware  corporation),  and Frantz
Medical Development Ltd.
("Frantz"), a New York corporation.


                                 R E C I T A L S

             A.  LaserSight  is  engaged  in the  development,  manufacture  and
marketing of ophthalmic lasers.

         B.  Frantz is engaged in the  development  and  manufacture  of various
products, including medical devices.

         C.  LaserSight  has been  granted  a  worldwide  limited  license  (the
"License") to practice the Patents (hereinafter defined) for the manufacture and
sale of Products  (hereinafter  defined)  pursuant  to a  Licensing  and Royalty
Agreement among LaserSight, Luis A. Ruiz, M.D. and Sergio Lenchig (collectively,
"Ruiz/Lenchig") (the "License Agreement").

         D.  LaserSight  desires  to grant a  sublicense  to Frantz  and  Frantz
desires  to  secure  the  exclusive  worldwide  right  to  manufacture  Products
exclusively for LaserSight.

         NOW,  THEREFORE,  in consideration of the mutual promises and covenants
contained the parties agree as follows:


1.       Definitions
         
         "Automatic  Corneal Shaper System" shall mean the complete  system used
to perform LASIK surgery which includes (i) disposable  microkeratome  with gear
box, suction ring and suction handle,  (ii) motor,  (iii) motor power cord, (iv)
tonometer,  (v) suction and power supply, (vi) foot switch, (vii) tubing, (viii)
user's manual, (ix) sterile packaging,  (x) control consoles, (xi) blades, (xii)
replacement  parts,  (xiii) lid speculum,  and other  component  parts which are
manufactured utilizing the Patents.
                                                            
         "Contract Year" shall mean each 12 consecutive  month period  beginning
on January 1 and ending on December 31.

         "Patents" shall mean U.S. Patent #5,133,726 and Patent Reissue #35,421,
both with respect to a  microkeratome  device,  including  all United States and

<PAGE>

foreign  patents  related  thereto  which may be issued in the future  including
amendments, reissues, improvements thereon, etc.

         "Product" or "Products" shall mean disposable  microkeratomes which are
manufactured utilizing the Patents.

         "Purchase" shall mean to order and take delivery of Products.

         "Specifications"  shall mean the  latest  specifications  for  Products
agreed to by LaserSight and Frantz which have been developed by Ruiz/Lenchig and
pursuant  to  which  Frantz  is  manufacturing  Products  for  LaserSight.   The
Specifications may only be amended or changed by written agreement of LaserSight
and Frantz.


2.       License To Manufacture Products
         
         LaserSight hereby grants Frantz an exclusive worldwide sublicense, even
as to  LaserSight,  under  the  License  Agreement  solely  for the  purpose  of
manufacturing Products exclusively for LaserSight.

         If Chiron Vision Corporation  ("Chiron") as agent,  owner, or assignee,
or any other  agent,  owner or  assignee  of U.S.  Patent  4,840,175  ("Peymen")
institutes any action which causes LaserSight to cease distributing  Products in
the United States (a "Trigger Event"), LaserSight and Frantz agree as follows:

         (a) 90 days following its receipt of notice of a Trigger Event,  Frantz
shall cease manufacturing Products in the United States.

         (b) Within 30 days after Frantz receives notice of the institution of a
Trigger  Event,  Frantz shall  determine the  feasibility  of its  manufacturing
Products  outside of the United  States.  In the event  Frantz  decides to cause
Products to be manufactured outside of the United States, Frantz shall:

                  (i) continue to have full  responsibility  for the manufacture
of Products,  including  all quality and warranty  requirements  as specified in
Paragraph 8; and

                  (ii) reduce Products price by an amount equal to fifty percent
of any reduction in Product  manufacturing  costs on a per unit basis  resulting
from the change in the  location of the  manufacturing  site to a  manufacturing
site  located  outside of the  United  States,  after any  initial  transfer  or
start-up expenditures.

                  In all  other  respects  the  terms  and  conditions  of  this
Agreement shall remain in full force and effect.

<PAGE>

         (c) In the event Frantz elects to not  manufacture  Product  outside of
the United States,  this Agreement shall terminate and within 60 days after such
election is made, Frantz shall transfer and cause to be delivered to LaserSight,
at the  expense  of  LaserSight,  all  molds,  engineering  drawings  and  other
properties previously delivered by LaserSight pursuant to Paragraph 4.



         (d) If Frantz elects not to manufacture  Product  outside of the United
States, Frantz shall offer reasonable assistance,  as Frantz shall determine, to
LaserSight to establish offshore manufacturing.  LaserSight shall pay Frantz for
any direct,  reasonable expenses  associated with such assistance.  Frantz shall
offer  to  sell  to  LaserSight  any  confidential  properties  related  to  the
manufacture  of Product which have been developed at Frantz's sole expense which
may include  process,  further design,  or other know-how  proprietary to Frantz
(the  "Manufacturing  Know-How").  In  consideration  for  the  receipt  of  the
Manufacturing Know-How,  LaserSight shall negotiate with Frantz in good faith to
pay a royalty not to exceed  $3.00 per unit of Product  produced by or on behalf
of  LaserSight  utilizing  the  Manufacturing  Know-How  for the duration of the
License  Agreement.  The sum of such  contemplated  royalty payment and transfer
price to LaserSight shall not exceed the transfer price associated with Products
as were being previously produced in the U.S.


3.       Obligations of Frantz
         
         Frantz shall be  responsible  for the  production  and  manufacture  of
Products in accordance with the  Specifications,  as may be amended from time to
time in accordance with this Agreement.  Frantz  acknowledges and agrees that it
shall have a limited  supply of Product  packaged on or before October 22, 1997.
The  parties  acknowledge  and  agree  that  such  supply  of  Product  shall be
considered "pre-production" Product and shall be subject to further modification
as requested  by  LaserSight.  Notwithstanding  anything set forth herein to the
contrary, if Frantz (i) fails to have a limited supply of Product packaged on or
before  October 22,  1997,  and (ii) such  failure was caused  solely by Frantz,
LaserSight  shall have the option to terminate this Agreement upon 10 days prior
written notice to Frantz,  and LaserSight  shall be entitled to pursue all legal
and  equitable  remedies  to which it may be entitled  in  connection  with such
breach.


4.       Obligations of LaserSight
         
         The parties  acknowledge  and agree that  Ruiz/Lenchig  have undertaken
certain  obligations to pay for and/or provide (or cause to be provided) certain
items related to the development of Products. The full and timely performance of
these obligations by Ruiz/Lenchig and the execution of the License Agreement are
essential  elements and conditions  precedent to the full and timely performance
by LaserSight and Frantz of their respective obligations under this Agreement.


<PAGE>

         LaserSight shall be responsible for the following obligations:

         (a)  LaserSight  shall provide Frantz with  Specifications,  design and
design  documentation  for Products and the  Automatic  Corneal  Shaper  System,
including  establishing and,  thereafter,  maintaining the design and associated
documentation.  Configuration  control shall be maintained by Frantz utilizing a
formal change control system the same or  substantially  similar to the standard
procedures used by Frantz.

         (b) LaserSight shall provide Frantz with a complete  Automatic  Corneal
Shaper  System during its  production  (for a duration of at least one month) to
allow testing and product review by Frantz of final production Product.

         (c)  LaserSight  shall  provide to the mold maker  designated by Frantz
purchase orders for (i) dual cavity automatic  production molds, and (ii) single
cavity  limited  production  molds,  as may be  necessary  for Frantz to achieve
project schedules.

         (d) LaserSight  shall be responsible  for the cost of any major repairs
and revisions to molds; provided,  however, if such repairs or revisions are the
result  of any  cause or event  attributable  to  Frantz  (normal  wear and tear
excepted),  Frantz  shall be  responsible  for the cost of any  such  repair  or
revision.  Such  revisions  shall be documented  and authorized by Frantz's Mold
Revision Route Sheet Procedure.

         (e) LaserSight  shall provide Frantz with all  documentation,  reports,
studies, protocols, and data regarding the quality, manufacture and distribution
of Product and  participate in the timely design reviews at each major phase and
as required to support project objectives, as determined by Frantz.

         (f) Lasersight  shall coordinate the performance of all clinical trials
necessary to assure  clinical  efficacy of Products.  Written  reports  shall be
provided to Frantz within 14 days of the completion of such trials.

         (g)  LaserSight  shall (i)  provide  Frantz  with  special  tooling and
special  equipment  required to produce  packaging  material and  packaging  for
Products  distribution,   or  (ii)  make  arrangements  for  the  packaging  and
sterilization of Products.

         (h)  LaserSight  shall  ensure that all  requirements  for  trademarks,
labeling and package design are satisfied.  Frantz shall be responsible  for the
implementation  and control of all  packaging  and labeling that is shipped with
Products.

         (i) LaserSight shall provide Frantz with all instructional inserts that
are required to be shipped with Products.

<PAGE>

5.       Purchase of Products
         
         (a) No later than October first of each year,  LaserSight shall furnish
Frantz with a forecast of the number of Products it expects to order during each
month of the  succeeding  Contract Year. No later than April first of each year,
LaserSight  shall  furnish  Frantz  with an  updated  forecast  of the number of
Products it expects to order  during  each  remaining  month of such year.  Such
forecasts and updates shall merely  represent  reasonable  estimates  based upon
LaserSight's then current business plans and shall not be Purchase  commitments.
LaserSight's  obligation to make firm Purchase commitments for Products shall be
governed by Paragraph 5(b).

         (b) During the term of this  Agreement,  on or before  each  January 1,
April 1, July 1 and October 1,  LaserSight  shall place firm Purchase orders for
the  quantities of Products to be delivered  during April,  May and June;  July,
August and September;  October, November and December; and January, February and
March,  respectively (each a "Quarterly Purchase Order"). Upon the issuance of a
Quarterly  Purchase Order by LaserSight and receipt by Frantz, the obligation of
LaserSight  to  Purchase  Product  shall be firm and  noncancellable;  provided,
however,  90 days  following  the receipt of notice of a Trigger  Event,  Frantz
shall cease  manufacturing  Products and  LaserSight  shall be  responsible  for
taking  delivery of Product  which is produced in  accordance  with  outstanding
Quarterly  Purchase  Orders during such 90 day period.  Each Quarterly  Purchase
Order shall be placed on LaserSight's  standard purchase order form.  Deliveries
shall be made  according to delivery dates  identified on such purchase  orders,
subject to Paragraph  5(c).  All terms and  conditions of this  Agreement  shall
supersede any terms and conditions of any Quarterly Purchase Order to the extent
the same may modify or is inconsistent therewith. Frantz shall be deemed to have
accepted a Quarterly  Purchase Order,  except to the extent of the quantities it
expressly  rejects in writing  within 10 business days of receipt of such order.
Frantz shall not  unreasonably  reject  quantities which are consistent with (i)
the most recent October  annual  forecast,  or (ii) the updated annual  forecast
furnished in April, as applicable, to be delivered by LaserSight to Frantz.

         (c) No later than September 30, 1997,  LaserSight shall issue to Frantz
an initial blanket  purchase order for a minimum of 200,000 units of Product for
delivery  during  the  period  commencing  on  the  calendar  month  immediately
following the month during which production of Product commences and terminating
30 months  immediately  thereafter;  provided,  however,  90 days  following its
receipt of notice of a Trigger Event, Franz shall cease manufacturing  Products,
notwithstanding anything set forth herein to the contrary.

         (d) Delivery terms shall be F.O.B. Frantz's  manufacturing  facility or
designated  sterilizing  facility.  Frantz  shall  ship  Products  in the manner
specified in the applicable  LaserSight  purchase order or as otherwise directed
by LaserSight in writing prior to shipment.

6.       Minimum Purchase
         
         LaserSight  shall  purchase  50,000  units of Product in each  Contract
Year.  The number of units of Product  for any  partial  Contract  Year shall be
prorated by  multiplying  50,000 units of Product times a fraction the numerator
of which  shall be the number of days the  Agreement  was in effect  during such
Contract Year, and the denominator of which shall be 365.


7.       Price and Payment
         
         Initial  Product  pricing shall be based upon Attachment "A" annexed to
this Agreement.

         Any scrap  cost  incurred  by  Frantz  over and above 5% of the cost of
goods sold of Products, as determined by Frantz, shall be an extra cost invoiced
to  LaserSight  on a quarterly  basis and shall be due and payable 30 days after
billing;  provided,  however (i) in no event  shall such scrap cost  incurred by
Frantz  exceed 20% of the cost of goods sold of Products,  and (ii) Frantz shall
notify LaserSight  immediately in the event such scrap cost equals or exceeds 5%
of the cost of goods  sold of  Products.  Scrap  cost shall have been due to the
inability  to  meet  specific  design   requirements  which  are  identified  as
questionable areas during final design reviews following clinical trials.

         Payment for monthly  shipments  shall be due to Frantz by bank check or
wire transfer 45 days after the date of invoice or shipment, whichever is later.

         Any increase in direct Product costs resulting from a change in Product
Specifications  shall be added to the price of Product.  Such  increase in price
shall  include a cost  markup of 10%.  Any  decrease  in  direct  Product  costs
resulting from Product design  modifications  or process  improvements,  whether
initiated  or  conceived  by Frantz or  LaserSight,  shall be shared  equally by
Frantz and LaserSight.

         Price  adjustments  shall be made on an annual  basis and be based upon
the increase in the current  producers price index over the base producers price
index (for finished goods less food and energy as quoted by the U.S.  Department
of Labor, Bureau of Labor Statistics).  The method for calculation of such price
adjustments are set forth on Attachment "B."


8.       Products Quality and Warranties
         
         Frantz shall maintain  quality  systems in compliance with ISO 9002 and
FDA/GMP requirements,  details of which shall be set forth in a Quality Plan for
Products to be provided by Frantz to LaserSight.
<PAGE>

         Frantz  shall  develop a Products  Master  Checklist/Plan  and maintain
elements of Product Master Record in accordance with the requirements defined by
LaserSight.

         Engineering  changes shall be accomplished  using Frantz change control
procedures.

         At least once every six months,  LaserSight  and Frantz  shall  jointly
participate  in  quality  and  regulatory  reviews to define  quality  plans and
objectives.

         Frantz warrants that Products  manufactured  pursuant to this Agreement
shall  meet  the  Specifications  and be  free  from  defects  in  material  and
workmanship  for a  period  which  shall be the  lesser  of (i) 24  months  from
delivery to  LaserSight,  or (ii) the shelf life of Products  as  determined  by
Frantz based upon tests of verification and validation relating to Sterilization
of Products and adhesives  utilized in connection  with producing  Product.  The
foregoing  warranty  shall not  extend to any  Products  or part  which has been
subject to accident or abuse or which has not been used,  operated or maintained
in the manner  prescribed  in  Products'  instructions  or with respect to which
unauthorized  repair or  alteration  has taken  place.  During  the term of this
warranty,  Frantz shall  replace  defective  Products or parts  thereof  without
charge within 30 days following  receipt of such  defective  Products by Frantz.
Frantz  shall bear all shipping  costs for the return of  defective  Products to
Frantz and of  shipping  replacement  Products  to  LaserSight  or  LaserSight's
customers,  as applicable.  Frantz shall have the right to designate the carrier
for the return of defective Products.

         The warranty of Frantz is limited to replacement of defective Products.
Return  authorization  must be  received  prior to the  return of any  Products.
Products must be cleaned prior to return and be returned in properly  identified
biohazard containers.

         EXCLUSION OF WARRANTIES- THE FOREGOING WARRANTY IS IN LIEU OF ALL OTHER
WARRANTIES,  EXPRESS OR IMPLIED,  INCLUDING  WITHOUT  LIMITATION,  WARRANTIES OF
MERCHANTABILITY.  IT IS  EXPRESSLY  UNDERSTOOD  AND AGREED BY THE  PARTIES  THAT
PURSUANT TO THIS  AGREEMENT,  FRANTZ  MAKES NO WARRANTY OF ANY KIND,  EXPRESS OR
IMPLIED, TO ANY PURCHASER OF PRODUCTS OTHER THAN LASERSIGHT.


9.       Term, Renewal and Termination
         
         Subject to the  earlier  termination  of the License  Agreement  as set
forth herein,  the initial term of this Agreement shall be 60 months  commencing
with the first full month of  production of Products by Frantz.  This  Agreement
shall  automatically  be renewed at the  expiration  of the initial  term for an
additional  one-year  period,  if not  terminated  in writing by either party at
least three  months prior to the  expiration  of the initial term or any renewal
term, as applicable.

         This  Agreement may also be terminated by LaserSight or Frantz upon the
occurrence of any of the following events:
<PAGE>

         (a) if any party is in default  with  respect to a material  obligation
under this Agreement, the affected party may give written notice of such default
to  the  defaulting  party;  thereafter,  unless  such  default  is  cured  or a
substantial  effort has been  initiated and continued to effect a cure within 30
days after the receipt of such notice, the non-defaulting  party, in addition to
its other remedies,  may elect to terminate this Agreement by additional written
notice to the defaulting party;

         (b) immediately upon notice to the other party, if LaserSight or Frantz

                  (i)      is  adjudicated  to be  insolvent  or  bankrupt  or a
                           petition  in   bankruptcy  is  filed  by  or  against
                           LaserSight   or  Frantz  and  such  petition  is  not
                           dismissed within 60 days after it is filed;

                  (ii)     admits in writing its  inability  to pay its debts as
                           they become due; or

                  (iii)    executes  an  assignment   for  the  benefit  of  its
                           creditors.

         If Frantz,  after consultation with LaserSight,  reasonably  determines
that  Frantz is unable to  manufacture  Products  in a reliable  and  consistent
manner as required by the clinical  performance  of Products,  then Frantz shall
continue  producing  Products  for a period of six months,  or for such  shorter
period as may be approved or directed by LaserSight,  immediately  following the
date of such determination,  and at the conclusion of such period this Agreement
shall be terminated.  Within 30 days after the date of such termination,  Frantz
shall  deliver  the  Manufacturing  Know-How  to  LaserSight,   without  charge.
Notwithstanding  anything set forth in this  Agreement to the  contrary,  Frantz
shall not be liable to any party for any damages or pecuniary  loss  suffered by
any party as a result of such decision to terminate  except for the  obligations
which survive termination as set forth in the next paragraph.

         No termination shall affect either party's rights to receive damages or
other legal or equitable  relief.  The obligations  under Paragraphs 8 (Products
Quality and Warranties), 10 (Product Recalls), 11 (Product Liability Insurance),
16  (Confidentiality),  17  (Indemnification),  and 18 (Patent Litigation) shall
survive  expiration or  termination  of this  Agreement.  Neither  expiration or
termination of this Agreement  shall relieve either party of any liability for a
breach or default which occurred prior to expiration or termination with respect
to any right or obligation which existed prior thereto.

         Notwithstanding  anything set forth in this  Agreement to the contrary,
if the License  Agreement  terminates for any reason,  (i)  LaserSight  shall be
responsible  for taking delivery of Product which is produced in accordance with
outstanding  Quarterly  Purchase  Orders  during  the  period  which  is 90 days
immediately  following the date of such termination;  and (ii) after such 90 day
period,  LaserSight's obligations pursuant to this Agreement shall terminate and
LaserSight  shall not be liable to any party for any damages or  pecuniary  loss

<PAGE>

suffered by any party as a result of such termination except for the obligations
which survive termination as set forth in the immediately preceding paragraph.


10.      Return of Property
         
         Within 10 days after the  termination of this Agreement for any reason,
Frantz shall return to LaserSight all items which have been previously delivered
to Frantz pursuant to Paragraph 4.


11.     Product Recalls
         
        In the event (i) any governmental authority issues a request, directive
or order that Product be recalled, (ii) a court of competent jurisdiction orders
such a recall, or (iii) LaserSight and Frantz,  after  consultation,  reasonably
determine  that  Product  should  be  recalled,  the  parties  agree to take all
appropriate  corrective  action.  In the event that such recall results from any
cause or event  attributable  to Frantz,  Frantz  shall be  responsible  for all
expenses of the recall. In all other cases,  LaserSight shall be responsible for
the  expenses of recall.  For the  purposes of this  Agreement,  the expenses of
recall shall  include,  without  limitation,  the expenses  associated  with (i)
providing notice of recall to purchasers of Product,  (ii) destruction or return
of the recalled Product, and (iii) LaserSight's costs for Product recalled,  but
not any direct and normal recurring expenses of LaserSight or Frantz.

12.      Product Liability Insurance
    
         Frantz shall maintain product liability insurance with single limits of
not less  than $2  million  in the  aggregate  per year for use of  Products  in
surgical  procedures.  The additional cost to Frantz of such insurance,  if any,
shall be added to the unit  price of Product  as a  separate  charge  based upon
Product units shipped and such cost shall be reviewed and revised  annually,  if
required.  Frantz  shall cause the  insurance  policy to name  LaserSight  as an
insured party.

         For a period of two years after  termination  of this  Agreement,  each
party shall maintain product liability  insurance with single limits of not less
than $2 million  in the  aggregate  per year and  provide  the other  party with
evidence of the continued existence of such insurance.


13.      Customer Complaint Procedure
    
         LaserSight (as  manufacturer of record) shall provide Frantz,  at least
monthly,  with customer complaint  information and Frantz shall be provided with
access to all information regarding the clinical performance of Products.
<PAGE>

         Customer  complaints  shall be  processed by  LaserSight.  Frantz shall
cooperate in such processing based upon receipt of written complaints  following
the return of Products in question.


14.      Regulatory Authority Matters
    
         LaserSight  shall have the  responsibility  for filing form 510(k) with
the FDA.

         LaserSight  shall  have  the  responsibility  to file  with the FDA all
medical  device  incidence  reports  and provide  Frantz with copies  thereof to
support product improvement activities.

         LaserSight  shall provide Frantz with all necessary  documentation  and
information  including  but not  limited  to  design,  manufacturing  and Patent
information to meet all regulatory requirements.


15.      Force Majeure
    
         The  failure  of either  party to  perform  an  obligation  under  this
Agreement,  except the obligation to make payments, shall not subject such party
to any liability to the other, and the performance of such party may be delayed,
if such  failure  is caused by  circumstances  beyond  that  party's  reasonable
control  such as acts  of God,  fire,  explosion,  flood,  drought,  war,  riot,
sabotage,  embargo,  strikes or other labor trouble, failure in whole or in part
of  suppliers  to  deliver  materials,   equipment  or  machinery  on  schedule,
interruption  of or delay in  transportation  or  compliance  with any  order or
regulation of any government  entity acting with authority  (including,  without
limitation,  the FDA). The party claiming the benefit of this Section shall give
immediate  notice to the other  party,  shall use its best  efforts  to avoid or
remove such cause or causes of non performance,  and shall otherwise continue to
perform hereunder.  LaserSight may terminate this agreement upon 30 days advance
written notice given to Frantz, if Frantz has invoked this Section to excuse its
performance  for a continuous  period of at least 30 days,  provided  LaserSight
reasonably  determines and submits to Frantz  satisfactory  supporting  evidence
that  it  can  remedy  such  non-performance  more  expeditiously  than  Frantz.
Suspension of a party's performance for such cause as described herein shall not
affect the running of the term of this Agreement.


16.      Notices
    
         Any notice shall be in writing, delivered by hand or sent to the other
party at its address stated below by certified mail,  return receipt  requested,
postage  prepaid,  and shall be deemed to be received  upon hand  delivery or 48
