                                   (UNAUDITED)


1. BASIS OF PRESENTATION:

        We prepared our Condensed Consolidated Interim Financial Statements in
conformity with Securities and Exchange Commission rules and regulations.
Accordingly, we condensed or omitted certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles. Please read our 1999 Annual
Report and Form 10-K to gain a more complete understanding of these interim
financial statements.

        We included in these interim financial statements all adjustments
(consisting primarily only of normal recurring adjustments) necessary to present
fairly our results for the interim period. Our interim financial statements have
not been audited.


2. EARNINGS PER SHARE:

        Basic earnings per share ("EPS") equals net income divided by the
weighted average number of common shares outstanding. Diluted EPS equals net
income divided by the weighted average number of common shares outstanding plus
dilutive potential common shares calculated in accordance with the treasury
stock method. All amounts in the following table are in thousands, except per
share data.

5. NEW ACCOUNTING PRONOUNCEMENTS

        In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standard No. 133 "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS No. 133") which establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments imbedded in other contracts, and for hedging activities. It requires
that we recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. We
are required to adopt SFAS No. 133 in the first quarter of 2001. We do not
expect the impact of adopting SFAS No. 133 to have a material effect on our
financial position or results of operations.

        In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB No. 101"), Revenue Recognition in Financial
Statements. It provides guidance on applying generally accepted accounting
principles to revenue recognition issues in financial statements. Among other
things, SAB No. 101 would result in a change from the established practice in
many industries of recognizing revenue at the time of shipment of a system, and
instead would delay recognition until the time of installation. A change in
revenue recognition reporting practices could have a material affect on revenue
in any particular reporting period. We will adopt SAB No. 101 as required in the
second quarter of 2000 and are evaluating the effect that SAB No. 101 may have
on our financial statements.


6. SUBSEQUENT EVENTS

        On May 4, 2000 we reported the settlement of a number of litigation
matters: (1) antitrust and patent claims between VISX and Jon Dishler, et al.,
(2) the action filed by John Taboada against Stephen Trokel, VISX, et al., and
(3) an action filed by a group of former clinical investigators of the system



                                                                          Page 7
<PAGE>   8

made by Taunton Technologies Corporation. In connection with these settlements,
VISX paid a total of approximately $12 million or $0.12 per share in one-time
payments and related costs and fees. Please see Part II, Item 1 - Legal
Proceedings in for a more detailed discussion of these matters.


ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

        In our Management's Discussion and Analysis of Financial Condition and
Results of Operations we review our past performance and, where appropriate,
state our expectations about future activity in forward-looking statements. Our
future results may differ from our expectations. We have described our business
and the challenges and risks we may face in the future in Items 1 and 3 of our
1999 Annual Report and Form 10-K and under "Business Risks and Quarterly
Fluctuations" below. Please read these items carefully.

OVERVIEW

        We develop products and procedures to improve people's eyesight using
lasers. Our principal product, the VISX STAR S2(TM) Laser System ("VISX
System"), is designed to correct the shape of a person's eyes to reduce or
eliminate their need for eyeglasses or contact lenses. The Food and Drug
Administration ("FDA") has approved the VISX System for use in the treatment of
most types of refractive vision disorders including nearsightedness,
farsightedness, and astigmatism. We sell VisionKey(R) cards to control the use
of the VISX System and to collect license fees for the use of our patents.

        The laser vision correction industry is evolving rapidly. New
developments and changes in market conditions frequently affect VISX and could
harm our business in the future. We may face increased competition from
manufacturers and users of other laser vision correction systems or new
competition from non-laser methods for correcting a person's vision. Patients'
and doctors' desire for laser vision correction using VISX Systems may not grow
or may decline in the future. Prices for our products and services may change as
the result of new developments in our market. Due to adverse determinations in
current and future patent and antitrust litigation, damages may be assessed
against us and we may not be able to enforce our current patent rights or
collect license fees. All of these factors could cause orders and revenues for
VISX Systems and VisionKey(R) cards to fluctuate or even decline. Accordingly,
our past results may not be useful in predicting our future results.

</TABLE>

        In the first quarter of 2000 we sold 86 laser systems as compared to 51
in the comparable period of the prior year. Average selling prices were largely
unchanged. In the U.S. we sold 47 laser systems in the first quarter of 2000 as
compared to 40 in the comparable period of the prior year. In international
markets we sold 39 laser systems in 2000 as compared to 11 in the prior year.
This growth in international markets was due to long term development efforts
such as hiring new distributors in recent years and expanding market support
programs.



                                                                          Page 8

        In the United States our customers purchased approximately 40% more
VisionKey(R) cards for laser vision correction surgery in the first quarter of
2000 than in the comparable period of 1999. The license fees associated with
these cards generated most of the increase in license, service and other
revenues in 2000 over 1999. We believe that card purchases increased because
laser vision correction has grown more popular with consumers. However, based on
our analysis of sales data and developments in the U.S. laser vision correction
market, we concluded that consumers' concerns about pricing of laser vision
correction was dampening the industry's potential for growth. In an effort to
address these concerns and to help broaden the appeal for laser vision
correction, on February 22, 2000 we reduced our U.S. license fee by 60% to $100
per procedure from the $250 fee we had previously charged since we first entered
the U.S. market in 1996. This change caused license, service and other revenue
to grow only marginally from the prior year, despite the 40% increase in the
quantity of VisionKey(R) cards sold in the U.S. While we expect that our license
fee reduction will result in a significant decline in license revenue, as well
as total revenue, for the remainder of 2000 as compared to the corresponding
periods of 1999, we believe the reduced fee will help promote faster growth of
laser vision correction procedures performed using VISX Systems in the U.S. We
cannot, however, predict with certainty when or whether growth in procedures
will offset the decline in procedure fee, nor even that procedures will
increase.

</TABLE>

        Cost of revenues increased in the first quarter of 2000 over the
comparable period of the prior year because we sold more systems and serviced a
larger installed base of systems. Marketing, general and administrative expenses
grew in the first quarter of 2000 over the comparable period of the prior year
due to a variety of factors. We increased spending on marketing programs
targeted towards consumers. Further, our legal expenses were higher due to
patent litigation with Nidek Co., Ltd., including proceedings before the
International Trade Commission, and other patent matters. We focused our
research and development on three areas: new capabilities for the VISX STAR
Excimer Laser platform, development of new products such as our WaveScan(TM)
Wavefront System, and research into new technologies. We continued to conduct
clinical studies and prepare submissions designed to obtain additional approvals
from the FDA and regulatory authorities in other countries.

        Interest income increased because we have generated cash from operations
over the past 12 months and have invested this in additional interest bearing
securities. We have accrued income taxes based on our expected effective income
tax rate for all of 2000, net of credits anticipated.


LIQUIDITY AND CAPITAL RESOURCES

        Cash, cash equivalents and short-term investments ("cash") and working
capital were as follows.

<PAGE>   10

        Cash decreased by $39 million in the first quarter months of 2000
because the $35 million we generated from operations was more than offset by the
$76 million we spent to repurchase 3.9 million shares of VISX stock on the open
market.

        Purchases of short-term investments represent reinvestment of the
proceeds from maturities of short-term investments and investment of cash and
cash equivalents into short-term investments.

        We anticipate that our current cash, cash equivalents and short-term
investments, as well as anticipated cash flows from operations, will be
sufficient to meet our working capital and capital equipment needs at least
through the next twelve months.


BUSINESS RISKS AND FLUCTUATIONS IN RESULTS

        Our results of operations have varied widely in the past, and they could
continue to vary significantly due to a number of factors, including:

        -    Patients' and doctors' acceptance of laser vision correction as a
             preferred means of vision correction;

        -    Competition from manufacturers and users of other laser vision
             correction systems;

        -    Introduction of new methods for vision correction which render our
             products less competitive or obsolete;

        -    Changes in prices for our products and services as the result of
             new developments in our markets;

        -    Developments in antitrust litigation to which we are currently a
             party, including legal actions brought against us by private
             parties and the legal action pending before the FTC;

        -    Developments in patent litigation that we have initiated,
             particularly to the extent that adverse developments in these
             proceedings could limit our ability to collect license fees from
             sellers and users of laser vision correction equipment; and

        -    Developments in patent litigation in which we are a defendant,
             particularly to the extent that adverse developments in these
             proceedings result in damages being assessed against VISX or render
             certain of our patents invalid or unenforceable, which would reduce
             the scope of proprietary protection available to us and could limit
             our ability to collect license fees from sellers and users of laser
             vision correction equipment.

        We anticipate that our revenue will be significantly lower in 2000 than
in 1999 as a result of the new $100 license fee we began charging in February,
2000. In the future, our revenue may fluctuate significantly. Any shortfall in
revenues below expectations would likely have an immediate impact on our
earnings per share, which could adversely affect the market price of our common
stock. Our operating expenses, which include sales and marketing, research and
development and general and administrative expenses, are based on our
expectations of future revenues and are relatively fixed in the short term.
Accordingly, if revenues fall below expectations, we will not be able to reduce
our spending rapidly in response to such a shortfall. This will adversely affect
our operating results. We devote significant resources to research and
development. We anticipate that the resulting new products and capabilities will
be well received by customers and generate future revenue, however the actual
results may vary from expectations. Due to the foregoing factors, we believe
that our results of operations in any given period may not be a good indicator
of our future performance.


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        There were no material changes during the three months ended March 31,
2000 to our exposure to market risk for changes in interest rates and foreign
currency exchange rates.



                                                                         Page 10

PART II. OTHER INFORMATION


ITEM 1. LEGAL PROCEEDINGS.

        VISX is engaged in numerous legal proceedings. Generally, the litigation
and other proceedings center on the validity or enforceability of VISX's
patents, and on whether infringement of the patents has occurred. In addition,
VISX's use of patents and its business practices are being contested in several
proceedings as violations of antitrust laws. The results of these complex legal
proceedings are very difficult to predict with certainty. Because a number of
the proceedings have issues in common, an adverse determination in one
proceeding could lead to adverse determinations in one or more of the other
pending proceedings. Adverse determinations in any of these proceedings could
limit our ability to collect equipment and use fees in certain markets, could
give rise to significant monetary damages, could prevent VISX from manufacturing
and selling the VISX System, and therefore could have a material, adverse effect
on our business, financial position and results of operations.

        For a complete description of legal proceedings, see VISX's annual
report on Form 10 -K for the year ended December 31, 1999. During the quarter
ended March 31, 2000, there were no material developments with respect to such
previously existing proceedings and no new material proceedings not previously
disclosed, except as follows:

        RECENT SETTLEMENTS

        As previously reported in our report on Form 8-K filed on May 4, 2000,
VISX recently settled a number of litigation matters. Among the claims settled
were the antitrust and other claims against VISX filed by Jon Dishler, DTC Eye
Surgery Center, Inc., DTC Eye Associates, PC, Laser Institute of the Rockies,
LLC, and TELCO The Excimer Laser Company Pty, Ltd. in the U.S. District court
for the District of Colorado. The settlement also included a resolution of the
claims filed in 1996 by Pillar Point Partners, Summit Partner, Inc. and VISX
Partner, Inc. against those same parties.

        Also settled was the action filed by John Taboada against Stephen
Trokel, VISX, and VISX Partner, Inc. in the U.S. District Court for the Western
District of Texas (USDC West. Dist. Tex. SA-97-CA-794-FB) seeking, among other
things, a declaration that Taboada is the inventor of VISX's U.S. Patent No.
5,108,388 (the "'388 Patent") and a payment of royalties received by VISX for
the `388 Patent. In connection with the settlement, the parties have signed and
will file with the court a stipulated judgment stating that Dr. Trokel is the
sole inventor of the `388 Patent. A stipulated dismissal was also filed in the
proceeding initiated by Taboada in U.S. District Court for the District Court of
Columbia in which Taboada had sought a stay of the reexemination of the `388
patent currently pending in the U.S. Patent and Trademark Office.

        VISX also settled an action filed against it by a group of former
clinical investigators of the system made by Taunton Technologies Corporation in
which the plaintiffs alleged federal antitrust law violations, breach of
contract, and unjust enrichment.

        In connection with these settlements, VISX paid a total of approximately
$12 million in one-time payments and related costs and fees.

        PATENT LITIGATION: NIDEK

        Neither VISX nor Nidek Co. Ltd. ("Nidek") filed an appeal of the
decision of the International Trade Commission and the deadline for filing any
such appeal has passed. VISX elected not to appeal the



                                                                         Page 11
<PAGE>   12

Commission's March 6, 2000 decision. VISX is pursuing its patent infringement
case against Nidek and its U.S. subsidiaries in the action pending in the U.S.
District Court for the Northern District of California described in Part I, Item
3 of our Annual Report and Form 10-K for the year ended December 31, 1999.

        PATENT LITIGATION: LASERSIGHT

        The action VISX initiated against LaserSight, Incorporated, LaserSight
Technologies, Inc. and LaserSight Centers Incorporated in November 1999 alleging
that LaserSight infringes VISX's U.S. Patent No. 4,718,418 (the "'418 patent")
has been consolidated with the action filed by LaserSight against VISX in
February 2000 in which LaserSight is seeking a declaration of non-infringement
and invalidity of the `418 patent and has alleged that VISX infringes
LaserSight's U.S. Patent No. 5,630,810. The consolidated case is captioned VISX,
Incorporated v. LaserSight Inc., et al. (USDC Del. 99-789-JJF) Discovery in the
consolidated action has commenced and trial is scheduled to begin in June 2001.

        SHAREHOLDER ACTIONS

        VISX and certain of its officers have been named as defendants in
several substantially similar securities class action lawsuits filed in
February, March and April 2000 in the U.S. District Court for the Northern
District of California. The plaintiffs in these actions purport to represent a
class of all persons who purchased VISX's common stock between March 1, 1999 and
February 22, 2000. The complaints allege that the defendants made misleading
statements in violation of the federal securities laws, including Section 10(b)
of the Securities Exchange Act of 1934. VISX expects the Court to appoint a lead
plantiff and consolidate the complaints in the near future.

        On April 24, 2000, a purported shareholder derivative action was filed
in the Superior Court of the State of California, Santa Clara County. The
complaint alleges that certain of VISX's officers and directors breached
fiduciary duties owed to VISX in connection with the circumstances alleged in
the securities class action complaints described above. VISX is a nominal
defendant in the action and no damages are sought from it.

        VISX believes that the claims asserted in the shareholder actions
described above are without merit, and we intend to defend against the claims
vigorously. Nevertheless, litigation is subject to inherent uncertainties and
thus there can be no assurance that this suit will be resolved favorably to VISX
or will not have a material adverse effect on VISX's financial position.
