Item 2.     Acquisition or Disposition of Assets.

    On August 18, 1997, LCA-Vision Inc. ("LCAV") closed an
acquisition of assets ("Closing" or "Closing Date").  On July 23,
1997, LCAV, Summit Technology, Inc. ("Summit") and Refractive
Centers International, Inc., a wholly-owned subsidiary of Summit
("RCII"), entered into an Acquisition Agreement (the "Agreement"),
pursuant to which LCA at Closing purchased from Summit 5,000,000
shares of RCII's Common Stock, par value $.01(which represented 100%
of the issued and outstanding shares of Common Stock of RCII held by
Summit) in exchange for 16,164,361 newly-issued shares of LCAV
Common Stock.  Nineteen (19) individuals (the "Option Holders") held
options for 312,500 shares of RCII Common Stock, 278,767 of which
were exercisable at Closing ("Exercisable Shares").  All 19 of the
Option Holders exercised their options prior to Closing and LCAV
also purchased all 278,767 shares of RCII Common Stock owned by the
Option Holders in exchange for 901,218 newly-issued shares of LCAV
Common Stock.  As a result of these transactions, LCAV in the
aggregate issued 17,065,579 shares of its Common Stock and came to
own 100% of the issued and outstanding RCII Common Stock.  The per
share consideration for RCII Common Stock was a number of shares of
LCAV Common Stock equal to the quotient of (a) 17,065,579 divided by
(b) the sum of the number of shares of issued and outstanding RCII
Common Stock on the Closing Date (5,278,767 shares) plus the number
of shares of RCII Common Stock into which options to purchase shares
of RCII Common Stock were exercisable on the Closing Date (0
shares).

     RCII owns and operates 19 laser vision correction centers and
has a working relationship with six (6) additional treatment sites
at university medical centers/hospitals, all in the U.S.A.
(collectively, the "Centers").  LCAV intends to continue to own and
operate or work with, as applicable, the Centers, subject to an
ongoing evaluation of the costs and benefits of maintaining each
Center, the economies of scale and market share created by the
addition of the Centers to similar centers already owned and
operated by LCAV and LCAV's business generally.

Independent Auditors' Report


The Board of Directors and Stockholders
Refractive Centers International, Inc.:

We have audited the accompanying consolidated balance sheets of
Refractive Centers International, Inc. and subsidiaries as of
December 31, 1996 and 1995, and the related consolidated statements
of operations, stockholder's equity, and cash flows for each of the
years in the three-year period ended December 31, 1996.  These
consolidated financial statements are the responsibility of the
Company's management.  Our responsibility is to express an opinion
on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement.  An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to
above present fairly, in all material respects, the financial
position of Refractive Centers International, Inc. and subsidiaries
at December 31, 1996 and 1995, and the results of their operations
and their cash flows for each of the years in the three-year period
ended December 31, 1996, in conformity with generally accepted
accounting principles.

                  Notes to Consolidated Financial Statements
              (in thousands, except share and per share amounts)

Years ended December 31, 1996, 1995, and 1994


1. Nature of  Business
Refractive Centers International, Inc. (the "Company") owns and
manages free-standing vision centers that provide primarily excimer
laser refractive surgery procedures to correct myopia
("nearsightedness").  This procedure is also called photorefractive
keratectomy ("PRK").  At December 31, 1996, the Company had nineteen
U.S. centers in operation.  Of the nineteen centers, the company
directly owns seven centers ("Company Centers"), operates five
centers pursuant to management and stock restriction agreements with
professional corporations ("P.C. Centers"), and operates seven
centers ("Satellite Centers") in conjunction with management
agreements with two teaching hospitals.  The Company also has
contracts with four additional teaching hospitals whereby the
Company receives fees for certain Company provided services.

Prior to opening its U.S. centers in 1996, the Company operated
centers in Europe.  The Company ceased all European operations in
April of 1996 (see note 9).

2. Summary of Significant Accounting Policies

Basis of Presentation
The Company is a wholly-owned subsidiary of Summit Technology, Inc.
("the Parent").  The Company has not operated as a stand alone
entity and its operating losses have been funded by the Parent.  In
addition, since the Company began U.S. operations in 1996,
administrative services have been provided by the Parent and certain
allocations have been made to present the financial statements of
the Company as a separate entity.  Management believes that the
allocation methods are reasonable.  No provisions for income taxes
has been made since the Company has incurred operating losses since
inception.  Interest expense has been recorded on all external debt
and no interest has been charged to the Company by the Parent for
advances made since the Company's primary source of financing has
been through equity.

Use of Estimates
The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period.  Actual results
could differ from those estimates.

Principles of Consolidation
The consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries after elimination of
material intercompany accounts and transactions. 


Revenue Recognition
The Company recognizes revenue on procedures at Company Centers when
the procedures are performed. The Company recognizes revenue for its
Satellite and P.C. Centers pursuant to the fee arrangements in the
management agreements.  The Company recognizes fees from its
contracts with teaching hospitals when the services are performed.

Cash Equivalents
Cash equivalents consist of certificates of deposit and highly
liquid debt instruments with original maturities of three months or
less. 


Financial Instruments
The carrying amounts of cash and cash equivalents, accounts payable
and accrued expenses approximate fair value because of the short-term maturity 
of these items. 

Concentration of Credit Risk
The Company limits its credit risk by arranging third party
financing for its customers or by requiring prepayment or credit
card payment.

Revenues

The Company, in general,  has entered into various arrangements to
deliver its services:  Company Centers, P.C. and Satellite Centers
and teaching hospitals.  Company Centers account for $1,025 of
revenue (34%) for the year ending December 31, 1996.  At Company
Centers the ophthalmologists are employed by the Company and all
revenue and expenses are included in the consolidated statements of
operations. 


Management fees of Satellite and P.C  Centers account for $1,338 of
revenue (44%) for the year ended December 31, 1996.  The Company is
responsible for and has included all expenses (including
professional fees) of the Satellite and P.C Centers in the
consolidated financial statements.  To date the Management fees
earned under agreements with Satellite and P.C. Centers have
exceeded the cash generated by the Centers.  Accordingly, management
fee revenues have been recorded only up to the amount of cash
realized.  

Management fees of  teaching hospitals account for $655 of revenue
(22%) for the year ended December 31, 1996.  The Company has
recognized the fee revenue as the services have been performed. 

Property  and Equipment
Property and equipment is stated at cost.  Laser equipment was
purchased from the Parent and accordingly is recorded at the
Parent's cost.  Property and equipment under capital leases is
stated at the lower of the present value of future minimum lease
payments or fair market value at the beginning of the lease term. 
Depreciation on property and equipment is calculated using the
straight-line method over the estimated useful lives of the assets
ranging from five to ten years.  Amortization of leasehold
improvements is calculated using the straight-line method over the
lease terms.

Organization costs
Organization costs are amortized over five years using the straight-line method.
  

Income taxes
Deferred tax assets and liabilities have been established for the
expected future tax consequences of events that have been recognized
in the Company's consolidated financial statements and tax returns. 
These deferred tax assets and liabilities are determined based on
the difference between the financial statement carrying amounts and
tax bases of assets and liabilities using currently enacted tax
rates that are expected to be in effect during the years in which
the differences are anticipated to reverse.  Deferred tax provision
(benefit) represents the change in the deferred tax asset balance. 
Tax credits are treated as reductions of income taxes in the year in
which the credits become available for income tax purposes.

Foreign Currency Translation
Assets, liabilities and expenses related to foreign operations are
remeasured in U.S. dollars at the appropriate exchange rates.  Gains
and losses resulting from remeasurement are included in other income
and expense.

Advertising and Marketing Expense
The Company expenses the production costs of advertising when the
advertising takes place.  For the years ended December 31, 1996,
1995 and 1994 the Company expensed $6,994, $1,263 and $30,
respectively.  The 1995 and 1996 expenses include advertising
expenses incurred pursuant to contracts with advertising and public
relations agencies.  The Company canceled all of its fixed contracts
with these firms and has no such commitments at December 31, 1996.

Stock Based Compensation
Prior to January 1, 1996, the Company accounted for its stock option
plan in accordance with the provisions of Accounting Principles
Board ("APB") Opinion No. 25, Accounting for Stock Issued to
Employees, and related interpretations.  As such, compensation
expense would be recorded on the date of grant only if the current
market price of the underlying stock exceeded the exercise price. 
On January 1, 1996, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 123, Accounting for Stock-Based
Compensation, which permits entities to recognize as expense over
the vesting period the fair value of all stock-based awards on the
date of grant.  Alternatively, SFAS No. 123 also allows entities to
continue to apply the provisions of APB Opinion No. 25 and provide
pro forma net income (loss) and pro forma earnings (loss) per share
disclosures for employee stock option grants made in 1995 and future
years as if the fair-value-based method defined in SFAS No. 123 had
been applied.  The Company has elected to continue to apply the
provisions of APB Opinion No. 25 and provide the pro forma
disclosure provisions of SFAS No. 123.

Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed
Of
The Company adopted the provisions of SFAS No. 121, Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed Of, on January 1, 1996.  This Statement requires that long-lived assets
 and certain identifiable intangibles be reviewed for
impairment whenever events or changes in circumstances indicate that
the carrying amount of an asset may not be recoverable. 
Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash
flows expected to be generated by the asset.  If such assets are
considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets
exceed the fair value of the assets.  Assets to be disposed of are
reported at the lower of the carrying amount or fair value less
costs to sell.  Adoption of this Statement did not have any impact
on the Company's financial position and results of operations. 


Net Loss Per Share 
Net loss per common share is based on the weighted average number of
common shares outstanding during each year.<PAGE>

                                      =====           ===

5. Financing and Leasing Arrangements
Leases

The Company leases its facilities under operating leases expiring in
2002.  Rent expense was approximately $777, $293 and $137,  for the
years ended December 31, 1996, 1995, and 1994, respectively.

At December 31, 1996, future payments of minimum rental payments
under noncancelable operating leases were as follows:

                                      Operating Leases
Year ending December 31:
   1997                                   1,082
   1998                                   1,092
   1999                                     976
   2000                                     892
   2001                                     359
Thereafter                                   23
                                          -----
                                         $4,424
                                          =====

Debt
In May of 1996, the Company obtained a $20.0 million unsecured term
loan that is guaranteed by the Parent.  At December 31, 1996, $16.3
million was outstanding under this facility and the obligation was
assumed by the Parent.

The interest rate at December 31, 1996 was 8.25%.  Principal
payments were made quarterly.


6. Stockholder's Equity

Common Stock
The Company has authorized 10,000,000 shares of common stock at $.01
par value. 

All of the Company's outstanding 5,000,000 shares have been owned by
its Parent since the Company's initial capitalization.  The Parent
has funded the Company with periodic advances that have been shown
as Investment by Parent in the consolidated statements of
stockholder's equity.

At December 31, 1996, the Parent agreed to advance cash and cash
equivalents of $10,000,000 to the Company.  The Company believes
that $10,000,000 is necessary to fund its operating losses and
negative cash flow for the next twenty four months.  If the Company
is unable to generate sufficient volume over the next twenty-four
months, additional financing will be necessary.  There can be no
assurances that the Company will be able to obtain additional
financing.

In addition, the Parent assumed certain debt obligations of the
Company (see note 5).


Stock Option Plan
In August 1993, the Company adopted a Stock Option Plan ("93 Plan")
to grant options to purchase shares of Company Stock and reserved
2,500,000 shares for issuance under the 93 Plan.  In September 1995,
the Company decreased the number of shares reserved from 2,500,000
to 800,000.  Options granted under the plan must be exercised not
later than 10 years from the date of grant.

The following table summarizes activity under the 93 Plan for each
of the years in the three year period ended December 31, 1996:

                                                  Weighted average

                          ========                     ====

There were 418,500, 38,750 and 1,829,750 shares available for grants
under the Plan at December 31, 1996, 1995 and 1994, respectively.
The weighted average fair value of options granted during 1996 and
1995 was $.13 per option.

Options on 97,000, 213,250 and 25,100 shares were exercisable at an
exercise price of $.50 under the Plan at December 31, 1996, 1995 and
1994, respectively.

The following table summarizes significant ranges of outstanding and
exercisable options under the 93 Plan at December 31, 1996:

        Options Outstanding                 Options Exercisable
- ----------------------------------------    -------------------
                    Weighted    Weighted                Weighted

$.50       318,500      8.0       $  .50     97,000      $  .50


The fair value of options at date of grant was estimated using the
Black-Scholes model with the following weighted average assumptions:

                                 1996           1995

Expected life                   5 years      5 years
Interest rate                   6.18%        6.38%
Volatility                      0%           0%
Dividend yield                  0%           0%

Stock based compensation costs  would have increased  the net loss
in 1996 and 1995 by $42 and $24, respectively if the fair values of
the options granted in that year had been recognized as compensation
expense on a straight-line basis over the vesting period of the
grant.  The pro forma effect on net income for 1996 and 1995 is not
representative of the pro forma effect on net income in future years
because it does not take into consideration pro forma compensation
expense related to grants made prior to 1995.


7. Income Taxes
The appropriate tax effect of each type of temporary difference and
carryforward that gives rise to significant portions of the deferred
tax assets and liabilities are as follows:
 
                                     December 31,

                               $    6              $  -
Deferred tax liability:
Other temporary differences         6                 -

                               ======              =====

Due to the uncertainty of future taxable income being generated, the
Company has recorded a valuation allowance against its deferred tax
assets.  The valuation allowance for deferred tax assets as of
December 31, 1994, was $933.  The net change in the total valuation
allowance for the years ended December 31, 1996 and  December 31,
1995  was $5,626 and $(211), respectively.

The provision for income taxes differs from the amount computed by
applying the federal income tax rate of 35% as a result of the
following:

                                     Year ended December 31,
                                 1996       1995         1994

           Notes to Consolidated Financial Statements
 



1.  Nature of  Business
Refractive Centers International, Inc. (the "Company") owns and
manages free-standing vision centers that provide primarily excimer
laser refractive surgery procedures to correct myopia
("nearsightedness").  This procedure is also called photorefractive
keratectomy ("PRK").  At December 31, 1996, the Company had nineteen
U.S. centers in operation.  Of the nineteen centers, the company
directly owns seven centers ("Company Centers"), operates five
centers pursuant to management and stock restriction agreements with
professional corporations ("P.C. Centers"), and operates seven
centers ("Satellite Centers") in conjunction with management
agreements with two teaching hospitals.  The Company also has
contracts with four additional teaching hospitals whereby the
Company receives fees for certain Company provided services.

Prior to opening its U.S. centers in 1996, the Company operated
centers in Europe.  The Company ceased all European operations in
April of 1996.

2.  Summary of Significant Accounting Policies

Basis of Presentation:
The Company is a wholly-owned subsidiary of Summit Technology, Inc.
("the Parent").  The Company has not operated as a stand alone
entity and its operating losses have been funded by the Parent.  In
addition, since the Company began U.S. operations in 1996,
administrative services have been provided by the Parent and certain
allocations have been made to present the financial statements of
the Company as a separate entity.  Management believes that the
allocation methods are reasonable.  No provisions for income taxes
has been made since the Company has incurred operating losses since
inception.  Interest expense has been recorded on all external debt
and no interest has been charged to the Company by the Parent for
advances made since the Company's primary source of financing has
been through equity.

Principles of Consolidation:
The consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries after elimination of
material intercompany accounts and transactions. 

(b)     Proforma financial information

        UNAUDITED PRO FORMA FINANCIAL INFORMATION



The following unaudited pro forma financial information (the
"Unaudited Pro Forma Financial Information") is based on the
historical financial statements of LCA-Vision and RCII and has
been prepared to illustrate the effects of the acquisition of RCII
and the related financing transactions.

The unaudited pro forma condensed consolidated statements of
operations for the year ended December 31, 1996 and the six months
ended June 30, 1997 give effect to the acquisition of RCII as if
such transaction had been completed by January 1, 1996 and January
1, 1997, respectively. The pro forma condensed consolidated
balance sheet as of June 30, 1997 has been prepared as if the
acquisition had occurred on such date.

The acquisition will be accounted for using the purchase method of
accounting in accordance with Accounting Principles Board Opinion
No. 16. The total purchase costs will be allocated to the tangible
and intangible assets based upon their respective fair values. The
allocation of the purchase price reflected in the unaudited pro
forma financial information is preliminary. The pro forma
adjustments are based on available information and certain
assumptions that management believes are reasonable in the
circumstances. The unaudited pro forma financial information is
not necessarily indicative of either future results of operations
or the results that might have occurred if the foregoing
transaction had been consummated on the indicated dates.

                       (dollars in thousands)


(A) The combined pro forma amounts do not reflect the elimination
of revenues and direct operating expenses for RCII centers which
will be closed by the Company. Management expects that the four
centers located in West Palm Beach, Florida; Miami, Florida;
Towson, Maryland and Chicago, Illinois will be closed by December
31, 1997.  The revenues and direct operating expenses for these
four centers for the periods presented are:

                   Year Ended               Six Months
                  December 31, 1996      Ended June 30, 1997

Revenues             $362                    $967
Direct operating
 expenses            $553                    $432

(B) The adjustment reflects additional depreciation and
amortization resulting from the allocation of the Company's
purchase price to the assets acquired, including an increase in
property and equipment and the recording of goodwill associated
with the Acquisition. Property and equipment acquired is amortized
over a weighted average of 17 years and goodwill is amortized over
7 years.

(C) The adjustments reflect cost savings for the year ended
December 31, 1996 and the six months ended June 30, 1997 resulting
from the elimination of redundant corporate general and
administrative expenses, RCII's parent company overhead allocation
and certain marketing costs that will not be recurring expenses of
the Company. Such pro forma cost savings are expected to be as
follows:


                                 Year ended     Six months ended
                             December 31, 1996   June 30, 1997

Salaries terminated             $   967            $  425
Corporate costs                   8,397               652
RCII parent company allocation    1,042                 -
                                   ----              -----
                                $10,406            $1,077

(D) Adjustment represents the elimination of RCII interest expense
to reflect interest expense based on the capitalization of the
Company.

(E) The adjustment represents the shares issued in conjunction
with the acquisition of RCII.

(F) The adjustment represents the reclassification of cash
acquired in the acquisition to restricted cash. In conjunction
with the acquisition of RCII, the Company entered into a new debt
facility with its primary lender which requires the company to
maintain $4 million on deposit with the bank.

(G) The adjustment represents the allocation of the purchase price
to the estimated fair value of property and equipment acquired.


   NOTES TO UNAUDITED PRO FORMA FINANCIAL INFORMATION (continued)

           (in thousands, except per share)

(H) The adjustment represents the recording of goodwill associated
with the acquisition. The purchase price is summarized as follows:


Issuance of 17,066 shares of LCA-Vision common stock valued at
$1.97 per share in exchange for all the outstanding shares of RCII
common stock                     $32,786


Acquisition costs                    400

                                ---------
Goodwill recorded               $ 15,977
                                =========


(I) Adjustment represents capitalized financing costs related to
renegotiation of the Company's credit facility.

(J) Adjustment represents accrued costs directly attributable to
the Acquisition, credit facility renegotiation and the issuance of
LCA-Vision common shares.

(K) Adjustment represents the recording of deferred tax
liabilities associated with the difference between the book and
the tax basis of assets and liabilities, excluding goodwill.

(L) Adjustment represents the net additional common stock issued
in connection with the acquisition of RCII after elimination of
historical common stock amounts for RCII, and the elimination of
the historical stockholders' equity of RCII as the acquisition
will be accounted for as a purchase.

(M) Adjustment represents effect of new credit facility.

time when a prospectus relating to the sale of the Distribution
Shares is required by law to be delivered in connection with sales
by an underwriter or dealer, of the occurrence of any event

prospectus so that, as thereafter delivered to the purchasers of
the registered Distribution Shares, such prospectus will not
contain an untrue statement of a material fact or omit to state

or incurred by LCA resulting from or in connection with breach of
any representation, warranty, covenant or agreement of Summit
contained in this Agreement or any document, agreement, instrument
or certificate delivered or filed pursuant hereto.

10.2 Indemnity Obligations of LCA.  LCA hereby agrees to indemnify
and hold Summit harmless from, and to reimburse Summit for, any
and all Losses suffered or incurred by Summit resulting from or in
connection with breach of any representation, warranty, covenant
or agreement of LCA contained in this Agreement or any document,

hereto.

10.3 Procedures for Indemnification for Third Party Claims.  If
any third party shall make a claim for which Summit or LCA is
entitled to indemnification under Section 10.1 or 10.2 hereof, the
following procedures shall apply:

10.3.1 Within thirty (30) days after receipt by an Indemnified
Party of any third party notice of any demand, claim or
circumstance that, with the lapse of time, would or could give
rise to a claim or the commencement (or threatened commencement)
of any action, proceeding or investigation with respect to which
the Indemnified Party intends to seek indemnification hereunder
("Asserted Liability"), the Indemnitee shall give notice thereof
(the "Claims Notice") to the Indemnifying Party.  The Claims
Notice shall describe the Asserted Liability in reasonable detail
and shall indicate the amount (estimated, if necessary) of the
indemnification claim that is being or may be asserted by the
Indemnified Party.

10.3.2 Promptly after receipt of a Claims Notice, but no later
than fifteen (15) days after such receipt, the Indemnifying Party
shall proceed to compromise or defend such Asserted Liability at
its own expense, employing counsel of its own choosing reasonably
satisfactory to the Indemnified Party.  The Indemnifying Party
shall immediately notify the Indemnified Party of the initiation
of such compromise or defense, and shall keep the Indemnified
Party informed as to the status and progress of such compromise or
defense.  The Indemnified Party shall reasonably cooperate in the
compromising of or the defending against such Asserted Liability,
and shall have the right to participate in any such compromise or
defense, and such participation shall not limit, impair or affect
its rights to indemnification hereunder.  If within fifteen (15)
days after delivery of the Claims Notice, the Indemnified Party
has not received from the Indemnifying Party any notice of the
initiation of the defense or compromise of the Asserted Liability,
the Indemnified Party shall be free to compromise or defend the
Asserted Liability at its sole election at the expense and risk of
the Indemnifying Party, and with full right of indemnification as
provided herein.

10.3.3 If any Indemnifying Party reasonably determines that its
interests in any Asserted Liability conflict or may conflict with
those of any Indemnifying Party, it may retain separate counsel
and separately participate in the defense or compromise of any
Asserted Liability, with full right of indemnification with
respect to any expense related thereto, including attorney's fees.

10.3.4 All parties shall make available to each other party any
books, records or other documents within its control which are
necessary or useful for the defense or compromise of any Asserted
Liability, and shall in all cases cooperate fully with one another
in the defense or compromise of any Asserted Liability.  In the
event that the interests of any one or more parties conflict with
the interests of any one or more other parties, such cooperation
shall not be required if it would jeopardize the defense of any
such party or parties.  

10.4 Claims by Summit or LCA.  Summit and LCA shall be entitled to
bring a direct claim against the other in connection with any
breach of any provision of this Agreement, including without
limitation, any claim for indemnification for any such breach
under Section 10.1 or 10.2 hereof, as the case may be.  

10.5 Survival of Representations and Warranties.  All
representations and warranties and, except as otherwise
contemplated in this Agreement, all covenants and agreements of
the parties contained in or made pursuant to this Agreement, and
the rights of the parties to seek indemnification with respect
thereto, or otherwise to seek recovery with respect to a breach
thereof, shall survive the Closing and shall expire eighteen (18)
months after the Closing Date. The expiration of indemnification
rights shall not relate to any claim made by an Indemnified Party
or claiming party under Section 10.3 or 10.4 until such claim has
been fully and finally resolved.

10.6 Limitations on Indemnification and Damages.  An Indemnifying
Party, both in its capacity as an indemnitor and as a party to
this Agreement, shall not be liable to an Indemnified Party, both
in its capacity as an indemnitee and as a party to this Agreement,
unless the aggregate amount of all Losses suffered by the
Indemnified Party in any capacity exceed $2,000,000 (the "Claims
Basket"), and shall not be liable for any individual Loss suffered
by the Indemnified Party in any capacity unless the amount of such
Loss exceeds $200,000 (the "Claims Minimum").  At such time as the
Claims Basket has been exceeded, the Indemnifying Party shall be
liable to the Indemnified Party for all Losses that are in excess
of the Claims Minimum, without further reference to the Claims
Basket.  Notwithstanding the foregoing, claims by an Indemnified
Party under Sections 3.2 , 3.4.1, 4.2 and 4.10 of this Agreement
shall not be subject to the Claims Basket.

10.7 Subrogation.  Any Indemnifying Party which indemnifies an
Indemnified Party for any matter pursuant to this Article X shall,
upon payment in full of the amount owed with respect to such
matter, be subrogated to the rights of such Indemnified Party
against all other Persons with respect to such matter, and, in its
own name or in the name of the Indemnified Party, may assert any
claim against any such Person with the Indemnified Party may have
with respect thereto.

seeking to terminate this Agreement under this Section 11.2 shall
give written notice to the other party specifying the basis for
the claim of breach, and the party receiving such notice shall
have fifteen (15) days to attempt to cure such breach, unless the
Outside Closing Date is less than fifteen days after the date of
such notice, in which case the receiving party shall have through
the Outside Closing Date to attempt such cure.  

11.3 Failure of Condition Precedent.  Summit and RCII, on the one
hand, and LCA, on the other, may terminate this Agreement as of
the Outside Closing Date, if any of the conditions precedent to

the Outside Closing Date.

11.4 Effect of Termination.  Upon any termination of this
Agreement, this Agreement shall terminate and be of no further
force and effect without any further liability of any party,

respect to any breaches or violations of any representations,
warranties, covenants or agreements contained in this Agreement.

     EXHIBIT B

                      SHAREHOLDERS' AGREEMENT

This Shareholders' Agreement is made and entered into this 18th
day of August, 1997 by and between LCA-Vision Inc., a Delaware
corporation ("LCA"), Summit Technology, Inc., a Massachusetts
corporation ("Summit") and the LCA shareholders listed on Schedule
A hereto ("Shareholders").

WHEREAS, the LCA and Summit have entered into a certain
Acquisition Agreement dated as of even date herewith (the
"Acquisition Agreement") pursuant to which LCA is acquiring from
Summit all of its shares of common stock of Refractive Centers
International, Inc., a Delaware Corporation ("RCII"), in
consideration for shares of LCA common stock; and

WHEREAS, one of the conditions to the closing of the Acquisition
Agreement is the execution and delivery of this Shareholders'
Agreement.

NOW THEREFORE, in consideration of the foregoing and for other
good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties agree as follows:

                                  ARTICLE I
                                 DEFINITIONS

Capitalized terms used in this Agreement and not otherwise defined
shall have the meanings ascribed to them in the Acquisition
Agreement.


                                  ARTICLE II
                             BOARD OF DIRECTORS

2.1 Nomination of Directors.  For the term of this Agreement, the
Shareholders agree, consistent with their fiduciary duties in any
and all capacities as shareholders, officers and directors of LCA,
to cause LCA, whether itself or through its Board of Directors
(the "Board") or a committee thereof, (a) to set the number of
directors that constitute the full Board at five (5) and (b) to
nominate individuals for election to the Board at each annual
meeting of the shareholders of LCA in the manner provided in this
Agreement (the "Designated Nominees").  The following individuals
shall  be the initial Designated Nominees:

Stephen N. Joffe
John C. Hassan
John H. Gutfreund
Ronald Herskowitz
William O. Coleman

2.2 Alternate Designated Nominees.   If there is a vacancy in the
Board occurring between annual meetings, or if one or more of the
initial Designated Nominees shall decline to stand for election to
the Board, the Shareholders and Summit shall appoint one or more
alternate Designated Nominees (each an "Alternate Designated
Nominee") in the following manner.  The Shareholders shall select
an individual to serve as the Alternate Designated Nominee, which
individual shall be independent both of LCA (except through
proposed service as a member of the Board) and of the
Shareholders.  The selected individual shall be subject to
Summit's approval, which shall not unreasonably be withheld. 
Summit's approval shall be deemed given if Summit has not
responded to the Shareholders within thirty (30) days of notice of
the identity of the selected individual.  Upon selection and
approval, such Alternate Designated Nominee shall for all purposes
be deemed a Designated Nominee under this Agreement.

2.3 Voting of Shares.  In any and all elections of directors of
the Board, whether in person or by proxy at a meeting of LCA
shareholders, or at a meeting of the Board called for the purpose
of filling a vacancy in the Board (to the extent not inconsistent
with the fiduciary duties of any director who is also a
Shareholder), the Shareholders and Summit shall vote all shares of
LCA stock owned by them to elect the Designated Nominees to the
Board and shall vote against any proposal that would violate any
term or provision of this Agreement.

                             ARTICLE III
                       COVENANTS OF SHAREHOLDERS

3.1 Payment of LCA Shareholder Debt.  The Shareholders agree that
they will not accept, demand or request any payment on the LCA
Shareholder Debt unless the earnings of LCA for the prior fiscal
year (before taxes, amortization of goodwill and depreciation, net
of capital expenditures for such fiscal year) exceeded One Million
Dollars ($1,000,000), and agree that payment in such event may be
made only to the extent of twenty-five percent (25%) of such
excess.  The Shareholders understand and agree that LCA shall
cause the instruments representing the LCA Shareholder Debt to
contain a legend to the effect of the foregoing.

3.2 Conversion of LCA Preferred Stock.  The Shareholders agree
that the per share Conversion Price of the LCA Interim Series
Preferred Stock shall not be less than Three and 50/100 Dollars
($3.50) per share.

3.3 Arms' Length Transactions.  During the term of this Agreement,
none of the Shareholders shall enter into any transaction with LCA
unless such transaction is at fair market value and approved by a
majority of LCA's  independent directors.


                           ARTICLE IV
                           MISCELLANEOUS

4.1 Binding Effect.  This Agreement shall be binding upon the
parties hereto and their respective heirs, successors and assigns. 
All shares of LCA Common Stock and LCA Preferred Stock at any time
owned by a party to this Agreement shall be subject to this
Agreement.  Shares of LCA Common Stock and LCA Preferred Stock can
be transferred by a party only if the transferee of such shares
agrees to be bound by this Agreement, except for transfers by
Summit pursuant to or not in violation of this Agreement or the
Registration Rights Agreement or to any Person who is not an
Affiliate of Summit.

4.2 Duration of Agreement.  This Agreement shall remain in effect
until the earlier of (i) the date which is five (5) years from the
date of this Agreement, and (ii) the date on which Summit owns
less than five percent (5%) of the issued and outstanding shares
of LCA Common Stock.  At any time that Summit owns less than such
percentage, this Agreement shall terminate and be of no further
force and effect, without the necessity of any action on the part
of any of the parties hereto.

4.3 Injunctive Relief.  It is acknowledged that it would be
impossible to measure the damages that would be suffered by a
party to this Agreement if the other parties were to fail to
comply with the provisions of this Agreement, and that in the
event of any such failure, monetary damages would not provide the
injured party an adequate remedy.  The parties shall, therefore,
be entitled to seek specific performance and injunctive relief for
any breach of this Agreement in a court of competent jurisdiction.

4.4 Governing Law.  This Agreement shall be governed by, and
construed in accordance with, the laws of the State of Delaware
without application of principles of conflict of laws, any suit
for the enforcement of this Agreement may be brought in the courts
of that state and all parties consent to the exclusive
jurisdiction of such courts and to service of process in any such
suit being made upon any party by mail at their respective
addresses set forth in below.

4.5 Notices.  All notices hereunder shall be in writing and shall

4.6 Waiver.   Waiver of any provision of this Agreement, in whole
or in part, in any one instance shall not constitute a waiver of
any other provision in the same instance, nor any waiver of the
same or another provision in another instance, but each provision
shall continue in full force and effect with respect to any other
then-existing or subsequent breaches.

Agreement shall be held to be invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby

provisions were not a part hereof.  Moreover, if any provision of

counterparts, all of which shall constitute one and the same
instrument.

4.12 Defaults.  Any breach or default by a party under the

                            EXHIBIT C
 
                 REGISTRATION RIGHTS AGREEMENT

REGISTRATION RIGHTS AGREEMENT, made and effective as of the 18th
day of August, 1997 (the "Effective Date"), is entered into by and
between LCA-Vision Inc., a Delaware corporation (the "Company"),
and Summit Technology, Inc., a Massachusetts corporation
("Summit").

1. Certain Definitions.  As used in this Agreement, the following
terms shall have the following respective meanings:

1.1. "Acquisition Agreement" means the Acquisition Agreement of
even date herewith, by and between the Company, Summit and
Refractive Centers International, Inc. ("RCII").

1.2. "Commission" means the Securities and Exchange Commission or
any other federal agency at the time administering the Securities
Act and the Exchange Act.

1.3. "Common Stock" means the Company's Common Stock, $.001 par
value, as authorized on the date of this Agreement, and any other
securities into which or for which any of the Common Stock may be
converted or exchanged pursuant to a plan of recapitalization,
reorganization, merger, sale of assets or otherwise.

1.4. "Exchange Act" means the Securities Exchange Act of 1934, or
any similar federal statute, and the rules and regulations of the
Commission thereunder, all as the same shall be in effect at the
time.

1.5. "Person" means an individual, corporation, partnership, joint
venture, limited liability company, trust, or unincorporated
organization, or a government or any agency or political
subdivision thereof.

1.6 "Retained Shares"  means the shares of Common Stock
representing Stock Consideration (as defined in the Acquisition
Agreement) retained by Summit after distribution of the
Distribution Shares (as defined in the Acquisition Agreement).

1.7 "Rule 144"  means Rule 144 promulgated under the Securities
Act, as the same shall be in effect at the time, or any successor
Rule.

1.8. "Securities Act" means the Securities Act of 1933, or any

Commission thereunder, all as the same shall be in effect at the

Section 4.2 hereof.

2. Transfer Restrictions.  Summit agrees that it shall not sell,
assign or otherwise transfer any of the Retained Shares for a
period of nine (9) months from the date of this Agreement.  After
such nine (9) month period, Summit agrees that it shall not sell,
assign or otherwise transfer any of the Retained Shares except as
hereinafter provided.  Nothing in this Agreement shall be
construed as prohibiting Summit from distributing the Distribution
Shares to shareholders of Summit as contemplated under the
Acquisition Agreement.

3. Demand Registrations.  If, at any time on or after the date
that is nine (9) months from the date hereof, Summit shall request
in writing that the Company file a registration statement under
the Securities Act for all or part of the shares of Common Stock
held by Summit on the date of such request, the Company will use
its best efforts to cause such number of shares of Common Stock as
requested by Summit to be registered under the Securities Act as
expeditiously as possible.

Summit agrees that it shall provide the Company such information
as the Company may reasonably request to enable the Company to
comply with any applicable law or regulation or to facilitate
preparation of the registration statement.  The Company shall not
be required to effect more than two (2) such demand registrations.

4. Sales Other Than by Demand Registrations. 

4.1 Rule 144.  If, at any time, the Company and/or Summit has not
been able to engage an underwriter to sell the Retained Shares
under Section 3 hereof at a price that is acceptable to Summit, or
if, at any time after the date that is twenty-four (24) months
from the date of this Agreement, Summit shall not have sold or
otherwise transferred all of the Retained Shares, Summit shall be
entitled to sell, assign or otherwise transfer the Retained Shares
pursuant to the provisions of Rule 144, (to the extent the
provisions of Rule 144 are available to Summit).  In such event,
the Company agrees to use its best efforts to facilitate and
expedite transfers of the Retained Shares pursuant to Rule 144,
which efforts shall include timely notice to its transfer agent to
expedite such transfers of Retained Shares.

4.2  "Shelf" Registrations.  (a)  If the provisions of subsection
(k) of Rule 144 are not available to Summit at any time that
Summit is entitled hereunder to transfer the Retained Shares
pursuant to Section 4.1 hereof, the Company shall, upon written
request of Summit, as expeditiously as possible, use its best
efforts to effect one or more so-called "shelf" qualifications and
registrations (collectively the "Shelf Registration Statement") on
the appropriate form for an offering to be made on a continuous
basis under Rule 415 promulgated under the Securities Act (or any
successor rule or similar provision then in effect) covering all
or such portion of the Retained Shares as Summit shall specify.  

(b)  The Company shall, from time to time, upon written request of
Summit, prepare and file with the Commission such prospectus
supplements and/or amendments to the Shelf Registration Statements
with respect to all or such portion of the Retained Shares that
Summit may determine to sell or transfer under the Shelf
Registration Statements (each, a "Take Down") and shall comply
with the provisions of the Securities Act and all rules thereunder
applicable to the Company, and shall otherwise cooperate with
Summit, with respect to the disposition of all Retained Shares
covered by such Shelf Registration Statement during the applicable
period in accordance with the intended methods of disposition of
the Retained Shares by Summit set forth in such Shelf Registration
Statement or amendment thereto or such prospectus or supplement
thereto, until all of the Retained Shares so registered shall have
been sold or transferred.

5. Effectiveness of Registration Statements.  The Company will use
its best efforts to maintain the effectiveness of any registration
statement (including any Shelf Registration Statement) pursuant to
which any of the Retained Shares are being offered until the
completion by the underwriters of the distribution pursuant to
such registration statement and the sale by Summit of all of the
shares of Common Stock registered pursuant to its request under
Section 3 or 4 hereof, and from time to time will amend or
supplement such registration statement, and shall cause the
prospectus included in any Shelf Registration Statement to be
supplemented by any required prospectus supplement and, as so
supplemented, to be filed pursuant to Rule 424 under the
Securities Act, in each case to the extent necessary to comply
with the Securities Act and rules promulgated thereunder and any
applicable state securities statute or regulation.  The Company
will also provide Summit with as many copies of the prospectus and
prospectus supplements contained in any such registration
statement as Summit may reasonably request.

6. Right of First Offer Upon Sale for Cash.

(a) Notwithstanding the provision of Sections 3 and 4 hereof, if
at any time during the term of this Agreement Summit wishes to
sell for cash all or any part of the Retained Shares, Summit shall
submit a written offer (the "Offer") to sell such shares (the
"Offered Shares") to LCA.  The Offer shall contain (a) the number
of Offered Shares, (b) the price at which the Offered Shares are
offered, which shall be the greater of (i) the average closing
price during the thirty (30) day period preceding the date of the
Offer less any commissions that would be applicable if Summit were
to sell the Offered Shares through a broker or placement agent and
(ii) any bona fide offer received by Summit for the Offered Shares
from another party within such 30 day period, (c) the proposed
closing date for the sale and purchase of the Offered Shares and
(d) such other terms and conditions as Summit shall deem relevant.

This section shall not apply to any sale or other transfer by
Summit of all or any part of the Retained Shares for any non-cash
consideration, including without limitation, any stock swap. 
Summit shall give the Company twenty-one (21) days' notice of any
such non-cash transaction.

(b)  If the Company desires to purchase the Offered Shares on the
terms and conditions in the Offer, it shall so notify Summit
within fifteen (15) days after submission of the Offer, and such
notice, together with the Offer, shall constitute a binding and
enforceable agreement for the sale and purchase of the Offered
Shares on the terms set forth in the Offer.  If the Company fails
to respond within such time period, or declines to purchase the
Offered Shares, Summit shall be free to dispose of the Offered
Shares in any manner it deems appropriate, consistent with the
other provisions of this Agreement or any other agreement Summit
has with the Company.

(c)  The foregoing rights of first offer shall be operative only
if they can be offered and exercised in compliance with all
applicable federal and state securities laws.

7. Indemnification of Summit.

7.1.   In the event that the Company registers any shares of
Common Stock under the Securities Act, whether pursuant to this
Agreement or the Acquisition Agreement, the Company will, to the
extent permitted by law, indemnify and hold harmless Summit,
(including its officers, directors, affiliates and partners), each
Selling Shareholder (as defined in the Acquisition Agreement) and
each Person, if any, who controls Summit or such Selling
Shareholder within the meaning of Section 15 of the Securities
Act, from and against any and all losses, claims, damages,
expenses (including reasonable attorneys' fees and expenses) or
liabilities joint or several, to which they or any of them become
subject under the Securities Act or under any other statute or at
common law or otherwise, and, except as hereinafter provided, will
reimburse Summit, each Selling Shareholder and each such
controlling Person, if any, for any legal or other expenses
reasonably incurred by them or any of them in connection with
investigating or defending any actions whether or not resulting in
any liability, including but not limited to any losses, claims,
damages, expenses, liabilities or actions arise out of or are
based upon any untrue statement or alleged untrue statement of a
material fact contained in the registration statement or any
filing with any state securities commission or agency, in any
preliminary or amended preliminary prospectus or in the final
prospectus (or the registration statement or prospectus as from
time to time amended or supplemented by the Company) or arise out
of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary
in order to make the statements therein not misleading, or any
violation by the Company of any rule or regulation promulgated
under the Securities Act or any state securities laws or
regulations applicable to the Company and relating to action or
inaction required of the Company in connection with such
registration, unless such untrue statement or alleged untrue
statement or omission or alleged omission was made in such
registration statement, preliminary or amended preliminary
prospectus or final prospectus in reliance upon and in conformity
with information furnished in writing to the Company in connection
therewith by Summit, any Selling Shareholder or any such
controlling Person, as the case may be, expressly for use therein.

7.2.  Promptly after receipt by Summit, a Selling Shareholder or
any controlling Person of notice of the commencement of any action
in respect of which indemnity may be sought against the Company,
Summit, such Selling Shareholder or such controlling Person, as
the case may be, will notify the Company in writing of the
commencement thereof, and, subject to the provisions hereinafter
stated, the Company shall assume the defense of such action
(including the employment of counsel, who shall be counsel
reasonably satisfactory to Summit, such Selling Shareholder or
such controlling Person, as the case may be), and the payment of
expenses insofar as such action shall relate to any alleged
liability in respect of which indemnity may be sought against the
Company.  Summit, such Selling Shareholder or any such controlling
Person shall have the right to employ separate counsel in any such
action and to participate in the defense thereof but the fees and
expenses of such counsel shall not be at the expense of the
Company unless the employment of such counsel has been
specifically authorized by the Company.  The Company shall not be
liable to indemnify any Person for any settlement of any such
action effected without the Company's consent (which consent shall
not be unreasonably withheld or delayed).  The Company shall not,
except with the approval of each party being indemnified under
this Section, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof
the giving by the claimant or plaintiff to the parties being so
indemnified of a release from all liability in respect to such
claim or litigation.

7.3.  In order to provide for just and equitable contribution to
joint liability under the Securities Act in any case in which
Summit, a Selling Shareholder or any controlling Person of Summit,
makes a claim for indemnification pursuant to this Section but it
is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of
time to appeal or the denial of the last right of appeal) that
such indemnification may not be enforced in such case
notwithstanding the fact that this Section provides for
indemnification in such case, then the Company and Summit, such
Selling Shareholder or such controlling Person, as the case may
be, will contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (after contribution from
others) in such proportion as is appropriate to reflect the
relative fault of the Company on the one hand and of Summit, such
Selling Shareholder or controlling Person on the other in
connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, as well as any other
relevant equitable considerations.  The relative fault of the
Company on the one hand and of Summit, such Selling Shareholder or
controlling Person on the other shall be determined by reference
to, among other things, whether the untrue or alleged untrue
statement of a material fact or omission or alleged omission to
state a material fact relates to information supplied by the
Company on the one hand or by Summit, such Selling Shareholder or
controlling Person on the other, and each party's relative intent,
knowledge, access to information and opportunity to correct or
prevent such statement or omission; provided, however, that, in
any such case, (A) Summit, such Selling Shareholder or controlling
Person shall not be required to contribute any amount in excess of
the public offering price of all such shares of Common Stock
offered by it pursuant to such registration statement; and (B) no
Person or entity guilt of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) will be entitled
to contribution from any Person or entity who was not guilty of
such fraudulent misrepresentation.

8. Indemnification of Company.

8.1.  In the event that the Company registers any of the Common
Stock under the Securities Act at the request of Summit pursuant
to Section 3 of this Agreement, Summit, to the extent permitted by
law, will indemnify and hold harmless the Company, each of its
directors, each of its officers who have signed or otherwise
participated in the preparation of the registration statement and
each Person, if any, who controls the Company within the meaning
of Section 15 of the Securities Act from and against any and all
losses, claims, damages, expenses or liabilities, joint or
several, to which they or any of them may become subject under the
Securities Act or under any other statute or at common law or
otherwise, and, except as hereinafter provided, will reimburse the
Company and each such director, officer or controlling Person for
any legal or other expenses reasonably incurred by them or any of
them in connection with investigating or defending any actions
whether or not resulting in any liability, insofar as such loses,
claims, damages, expenses, liabilities or actions arise out of or
are based upon any untrue statement or alleged untrue statement of
a material fact contained in the registration statement or any
filing with any state securities commission or agency, in any
preliminary or amended preliminary prospectus or in the final
prospectus (or in the registration statement or prospectus as from
time to time amended or supplemented) or arise out of or are based
upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary in order to make
the therein not misleading, but only insofar as any such statement
or omission was made in reliance upon and in conformity with
information furnished in writing to the Company in connection
therewith by Summit expressly for use therein; provided, however,
that Summit's obligations hereunder shall be limited to an amount
equal to the proceeds received by Summit of the shares of Common
Stock sold in such registration.

8.2.  Promptly after receipt of notice of the commencement of any
action in respect of which indemnity may be sought against Summit,
the Company will notify Summit in writing of the commencement
thereof, and Summit shall, subject to the provisions hereinafter
stated, assume the defense of such action (including the
employment of counsel, who shall be counsel reasonably
satisfactory to the Company) and the payment of expenses insofar
as such action shall relate to the alleged liability in respect of
which indemnity may be sought against Summit.

8.3.  The Company and each such director, officer or controlling
Person shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and
expenses of such counsel shall not be at the expense of Summit
unless employment of such counsel has been specifically authorized
by Summit.  Summit shall not be liable to indemnify any Person for
any settlement of any such action effected without Summit's
consent (which consent shall not be unreasonably withheld or
delayed).

9. Damages.  The Company recognizes and agrees that Summit will
not have an adequate remedy if the Company fails to comply with
this Agreement and that damages may not be readily ascertainable,
and the Company expressly agrees that, in the event of such
failure, it shall not oppose an application by Summit or any other
Person entitled to the benefits of this Agreement requiring
specific performance of any and all provisions hereof or enjoining
the Company from continuing to commit any such breach of this
Agreement.

10. Further Obligations of the Company.  Whenever under the
preceding Sections of this Agreement, the Company is required
hereunder to register shares of Common Stock, it agrees that it
shall also do the following:

10.1 Within 60 days of any request hereunder, file with the
Commission a registration statement, in form and substance
required by the Securities Act, with respect to such Common Stock
and use its best efforts to cause that registration statement to
become effective;

10.2 As expeditiously as reasonably possible, furnish to Summit,
such reasonable number of copies of such registration statement,
each amendment and supplement thereto (in each case including all
exhibits thereto and documents incorporated by reference therein)
and the prospectus included in such registration statement,
including each preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents
Summit may reasonably request in order to facilitate the public
sale or other disposition of the Common Stock owned by it;

10.3 After the filing of the registration statement, promptly
notify Summit of any stop order issued or, to the knowledge of the
Company, threatened to be issued by the Commission and use all
commercially reasonable efforts to prevent the entry of such stop
order or to remove it if entered;

10.4 Enter into a written agreement with the managing underwriter
in such form and containing such provisions as are customary in
the securities business for such an arrangement between such
underwriter and companies of the Company's size and investment
stature;

10.5.  Furnish to Summit such copies of each preliminary and final
prospectus and such other documents as Summit may reasonably
request to facilitate the public offering of shares of Common
Stock held by Summit;

10.6. Use its best efforts to register or qualify the Common Stock
covered by said registration statement under the applicable
securities or "blue sky" laws of such jurisdictions as Summit may
reasonably request;

10.7  Cooperate with Summit in taking all action in connection
with completing the public offering of Common Stock, including but
not limited to hiring, at the expense of the Company, investment
bankers acceptable to Summit to, among other things, execute an
institutional investor "roadshow", sell the Common Stock in the
offering, make a market in the Common Stock, and provide research
coverage on the Company;

10.8. Furnish to Summit a "signed counterpart" of:

(a) an opinion of counsel for the Company, dated the effective
date of the registration statement, and

(b)  "comfort" letters signed by the Company's independent public
accountants who have examined and reported on the Company's
financial statements included in the registration statement, to
the extent permitted by the standards of the American Institute of
Certified Public Accountants, covering substantially the same
matters with respect to the registration statement (and the
prospectus included therein) and tin the case of the accountants'
"comfort" letters) with respect to events subsequent to the date
of the financial statements, as are customarily covered in
opinions of issuer's counsel and in accountants' "comfort" letters
delivered to the underwriters in underwritten public offerings of
securities,

in each case to the extent that the Company is required to deliver
or cause the delivery of such opinion or "comfort" letters to the
underwriters in an underwritten public offering of securities;

10.9  As promptly as practicable, notify Summit, at any time when
a prospectus relating to the sale of the Common Stock is required
by law to be delivered in connection with sales by an underwriter
or dealer, of the occurrence of any event requiring the
preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of the registered
Common Stock, such prospectus will not contain an untrue statement
of a material fact or omit to state any material fact required to
be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not
misleading, and as promptly as practicable make available to
Summit and to the underwriters any such supplement or prospectus;

10.10.  Permit Summit and its counsel or other representatives to
inspect and copy such corporate documents and records as may
reasonably be requested by them;

10.11.  Furnish to Summit a copy of all documents filed and all
correspondence from or to the Commission in connection with any
such offering of securities;

10.12.  Use its best efforts to insure the obtaining of all
necessary approvals from the National Association of Securities
Dealers, Inc.; and

10.13.  Otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission, and make
available to its security holders, as soon as reasonably
practicable, an earnings statement covering the period of at least
twelve months, but not more than eighteen months, beginning with
the first month after the effective date of the registration
statement filed in connection with the consummation of the
Acquisition Agreement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and Rule 158
thereunder.

11. Expenses.  The Company shall bear all costs and expenses of
each registration under this Agreement, including, but not limited
to, printing, legal and accounting expenses, Securities and
Exchange Commission and National Association of Securities
Dealers, Inc. filing fees and expenses, and "blue sky" fees and
expenses and the reasonable expenses of Summit in connection with
the registration of its shares of Common Stock; provided, however,
that Summit shall bear the expenses of any underwriter's fees,
commissions or discounts in connection with such registrations,
and that the Company and Summit shall share the costs of any
accountant's "comfort letters" obtained in connection with any
Take Downs under a Shelf Registration Statement pursuant to
Section 4.2 hereof.  

The Company shall also pay all expenses in connection with any
registration initiated pursuant to this Agreement which is
withdrawn, delayed or abandoned at the request of the Company,
unless such registration is withdrawn, delayed or abandoned solely
because of any actions of Summit.

12. Delay of Registration.  For a period not to exceed 90 days,
the Company shall not be obligated to prepare and file, or
prevented from delaying or abandoning, a registration statement
pursuant to this Agreement at any time when the Company, in its
good faith judgment with advice of counsel (as certified by an
officer of the Company in a certificate delivered to Summit)
reasonably believes:

12.1. That the filing thereof at the time requested, or the
offering of Common Stock pursuant thereto, would materially and
adversely affect (a) a pending or scheduled public offering of the
Company's securities, (b) an acquisition, merger,
recapitalization, consolidation, reorganization or similar
transaction by or of the Company, (c) preexisting and continuing
negotiations, discussions or pending proposals with respect to any
of the foregoing transactions, (d) the financial condition of the
Company in view of the disclosure of any pending or threatened
litigation, claim, assessment or governmental investigation which
may be required thereby or any other material Company matter; and

12.2.  That the failure to disclose any material information with
respect to the foregoing would cause a violation of the Securities
Act or the Exchange Act.

The Company may exercise its rights under this Section only once
during any twelve (12) month period.

13. Approval of Underwriter.  Any managing underwriter engaged by
the Company in any registration made pursuant under this Agreement
shall require the approval in writing of Summit and the consent of
the Company, which consent shall not be unreasonably withheld.

14. No Waiver; Cumulative Remedies.  No failure or delay on the
part of any party to this Agreement in exercising any right, power
or remedy hereunder shall operate as a waiver thereof; nor shall
any single or partial exercise of any such right, power or remedy
preclude any other or further exercise thereof or the exercise of
any other right, power or remedy hereunder.  The remedies herein
provided are cumulative and not exclusive of any remedies provided
by law.

15. Amendments, Waivers and Consents.  Except as hereinafter
provided, changes in or additions to this Agreement may be made,
termination of this Agreement, and compliance with any covenant or
provision set forth herein may be omitted or waived, if consented
to in writing by the Company and Summit.  Any waiver or consent
may be given subject to satisfaction of conditions stated therein
and any waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

16. Addresses for Notices.  All notices, requests, demands and
other communications provided for hereunder shall be in writing
(including telegraphic communication) and mailed, telegraphed or
delivered to each party at the address set forth in below or at
such other address as to which such party may inform the other
parties in writing in compliance with the terms of this Section. 
All such notices, requests, demands and other communications
shall, when mailed (which mailing must be accomplished by first
class mail, postage prepaid; electronic facsimile transmission;
express overnight courier service; or registered mail, return
receipt requested) or telegraphed, and shall be considered to be

                LCA-VISION COMPLETES ACQUISITION OF
                ALL SUMMIT LASER EYE SURGERY CENTERS

                    NOW NATION'S LARGEST PROVIDER
                  OF NEW VISION CORRECTION PROCEDURE

Dr. Ronald Herskowitz Named Chief Officer of Expanded Company

         LCA's Board Of Directors Will Also Be Enlarged


CINCINNATI, August 19 -- LCA-Vision Inc. (NASDAQ:LCAV), the
leading facility chain operator in the fast-growing laser vision
correction sector, said today it has completed acquisition of
Summit Technology, Inc.'s Refractive Centers International
subsidiary in exchange for 17 million shares of common stock.  The
transaction positions LCA-Vision as the nation's largest provider
of the new laser vision treatment procedure with twice the number
of locations as its nearest competitor.

Refractive Centers International has 19 wholly owned-and-operated
facilities around the country and a working relationship with six
additional treatment sites at prestigious university medical
centers/hospitals.  Refractive Centers International's total 1997
revenues are projected at $6 million.  LCA-Vision's projected
annualized 1997 revenues are $14.4 million.

Under terms of the agreement, LCA-Vision will file a registration
statement with the Securities and Exchange Commission for the
newly-issued shares within 90 days.  Summit has announced its
plans to retain a just-under 20 percent stake in LCA and
distribute the balance of the new shares to its shareholders after
the shares have been registered with the S.E.C.

Consistent with terms of the acquisition agreement, LCA-Vision
also announced that Dr. Ronald Herskowitz has been named chief
operating officer of LCA-Vision and that the company's board will
be changed and enlarged.  Dr. Herskowitz was formerly executive
vice president of Refractive Centers International, Inc., the
acquired Summit subsidiary.  Prior to that, he was a vice
president at Bausch & Lomb.

With the acquisition, LCA-Vision will have 40 major vision
correction centers in the U.S., two facilities in Canada, and one
in Europe.  The company now provides the most advanced, state-of-the-art laser 
technology available for the correction of myopia,
or near-sightedness, and astigmatism.  The one-hour, out-patient
treatment effectively eliminates patients' dependence on glasses
or contact lenses.

Dr. Stephen Joffe, LCA-Vision president and chief executive
officer, who remains the company's largest shareholder, commented:
"This acquisition dramatically alters the retail laser eye surgery
market, strategically positioning LCA-Vision as the clear industry
leader with an aggressive new senior management team headed by Dr.
Herskowitz.  We are unchallenged in terms of locations, number of
affiliated physicians and optometrists, procedures performed,
clinical experience, and marketing expertise.

"The acquired Summit centers will give us a presence in many major
new markets, making LCA-Vision a national player.  We have the
most recognizable brand-name in the field and an unmatched track
record for the correction of myopia and astigmatism using FDA-approved, 
laser-assisted technology.  Today, LCA has the size,
critical mass, and capital resources to define and lead this
young, rapidly-growing, potentially huge industry."

Dr. Joffe added that the combination of the two companies with
their proven management and marketing techniques will also produce
significant economics of scale and improved profitability.

He noted further that patient acceptance of laser treatment for
vision correction continues to accelerate rapidly, reflecting the
impact of strong word-of-mouth and media exposure.  "We are
already well ahead of projections for 1997.  Patient procedure
volume at our existing 18 centers for the second quarter was up 44
percent over the first quarter and we are running well ahead of
plan for the first six months of 1997."

LCA-Vision centers have, to date, completed over 10,000 of these
procedures, known technically as photo refractive keratectomy, at
an average cost of $2,000-$2,500 per eye.  An estimated 130
million Americans require some kind of vision correction,
including 25 to 30 million contact lens wearers.  Additionally,
new procedures are now undergoing FDA evaluation for the treatment
of hyperopia, or far-sightedness, which will further increase the
potential market beyond the current 70 million myopic and
astigmatic patients.

Among the laser vision correction centers that LCA-Vision will
acquire from Summit are sites in Agoura Hills, Glendale, San
Bernardino, and Torrance, California (UCLA Laser Refractive
Centers in the L.A. area); San Jose, Concord, and San Francisco,
California (Stanford University Laser Centers); Costa Mesa,
California; Chicago, Vernon Hills, and Schaumburg in Illinois
(Rush Eye Laser Centers); and Columbus (Worthington), Ohio.

Also, West Palm Beach, Miami, and Plantation in Florida; Bethesda,
Maryland; and Tysons Corner, Virginia (George Washington
University Refractive Laser Centers in the D.C. area); Towson,
Maryland; and Minneapolis (Edina), Minnesota.

The hospital/university medical center-based sites include those
affiliated with the UCLA/Jules Stein Eye Institute in Los Angeles;
Stanford Medical Center in Stanford, California; Rush-Presbyterian
- - St. Luke's Medical Center in Chicago; George Washington
University Medical Center in Washington, D.C.; the Cleveland
Clinic Foundation in Cleveland; and the University of Iowa.

LCA-Vision's existing facilities are located in Cincinnati,
Columbus, Cleveland, Warren, Dayton, and Toledo, Ohio; Buffalo,
Albany, New York City, and Westchester County, New York State;
Charlotte, North Carolina; Toronto and Ft. Erie, Canada; Savannah,
Georgia; Baltimore, Maryland; Clearwater, Florida; Mountain View
(Silicon Valley), California; and Helsinki, Finland.

           LCA-VISION NAMES THREE NEW MEMBERS TO COMPANY'S BOARD
             INCLUDING PROMINENT WALL STREETER JOHN GUTFREUND


CINCINNATI, August 21 -- LCA-Vision (NASDAQ-LCAV) today announced
the appointments of John H. Gutfreund, William O. Coleman, and Dr.
Ronald Herskowitz to the company's board of directors and the
resignations from the board of founding family members Sandra
Joffe and Craig Joffe.

The new appointments will increase the number of LCA-Vision's
directors to five and bring strong financial and specialized
management expertise to the company.  Continuing on the board are
Dr. Stephen Joffe, chairman, president, and chief executive
officer and outside director John Hassan.

Naming of the new directors implements provisions of LCA-Vision's
recently-completed acquisition of Summit Technology, Inc.'s laser
vision correction subsidiary.  LCA-Vision now operates the largest
chain of laser eye treatment sites in the U.S. with 40 locations
across the country plus two centers in Canada and one in Europe.

Mr. Gutfreund, 67, a leading Wall Street figure for over three
decades, was chief executive officer and board chairman of Salomon
Brothers from 1981 to 1991.  He is currently president of
Gutfreund & Company, a New York-based financial consulting firm. 
Mr. Coleman, 68, a retired senior executive with Procter & Gamble
Corporation, currently serves as trustee of the multi-billion-dollar P&G 
Retirement Trusts.

Dr. Herskowitz, 43, was recently named chief operating officer of
LCA-Vision.  He had been executive vice president of Summit
Technology, Inc. in charge of the chain of vision correction
centers acquired by LCA earlier this month.  

Commenting on the appointments, Dr. Joffe said: "We are extremely
gratified that two such distinguished representatives from the
world of finance and business as Mr. Gutfreund and Mr. Coleman
have agreed to serve on LCA's board as outside directors and that
our newly-named chief operating officer, Ron Herskovitz, will be
joining them.

"Their presence underscores LCA's new dominant position in the
laser eye surgery sector, following the Summit acquisition.  With
the number of LCA shareholders and locations now significantly
increased, the managerial experience, expertise and guidance
provided by the new directors will be especially valuable."

Mr. Gutfreund, whose financial consulting firm has advised some of
the nation's top companies, is a past vice chairman of the New
York Stock Exchange (1985-87) and a former member of the Board of
Directors of the Securities Industry Association.  He has also
served as president of the Bond Club of New York and as a member
of The Trilateral Commission.  LCA-Vision's newest board member is
a 1951 graduate of Oberlin College.

Mr. Coleman spent most of his professional career at Procter &
Gamble.  He held a series of key managerial positions with the
company, rising, successively, from general sales manager to vice
president, food products, vice president, International/Latin
America, vice president, professional affairs, and most recently,
vice president, special projects.  

In the public sphere, he has served as general chairman of the
United Way Campaign, vice president of the University of
Cincinnati Foundation, president of the Boys & Girls Clubs of
Cincinnati, and director of the Greater Cincinnati Foundation. 
Mr. Coleman is a graduate of the University of Oklahoma and served
as an officer with the U.S. Navy during the Korean War.

Dr. Herskowitz, who holds university degrees in optometry and
chemistry, joined Summit in 1993.  Previously, he had been vice
president, research and development and vice president, technical
affairs, with the Polymer Technology Corp. subsidiary of Bausch &
Lomb.  Dr. Herskowitz is a graduate of Knox College and the
Illinois College of Optometry.
