         On April 20, 2001, Mr. Icahn issued a press release and prepared a
letter for further distribution to stockholders of VISX, Incorporated, which
press release and letter are attached hereto as Exhibit 1 and Exhibit 2,
respectively.

                              FOR IMMEDIATE RELEASE


        ICAHN SUBMITS PROPOSAL FOR CASH MERGER WITH VISX AT $32 PER SHARE

New York, New York   April 20, 2001. In a letter sent today by Carl C.
Icahn to Ms. Elizabeth Davila, the CEO of VISX, Inc., Mr. Icahn stated "I was
happy to read in your April 18th press release that you are 'receptive' to
proposals for VISX.... [Therefore] I would like to make the following proposal:
I would be willing to engage in a cash merger with VISX, in which VISX
shareholders would receive $32 per share, subject to due diligence and
financing."

Mr. Icahn noted the significant commitment of money, time and effort necessary
in order to investigate such a transaction, but declared that "if VISX agrees
with me to submit to a vote of shareholders the best offer of $32 per share or
higher from any qualified bidder, then I will be willing to commit the
significant funds needed to commence the necessary effort to conduct due
diligence and to attempt to raise the financing for the transaction. I have been
in contact with the Industrial Bank of Japan, a member of the Mizuho Financial
Group, and they are prepared to commence due diligence efforts immediately. If
the results of due diligence are acceptable, one of my affiliated companies
would provide a significant portion of the purchase price in order to effectuate
the offer, in addition to the funds to be derived from financing sources."

Mr. Icahn stated that he could not assure that his efforts will ultimately
result in his consummation of the transaction, but that it was his "belief that
in any event [his] efforts, together with a clear commitment by VISX, may move
the auction process forward and bring out other potential bidders."

A price of $32 per share is more than 3 1/2 times higher than last year's
intraday low of $8.75 per share. Mr. Icahn observed that if management is
unwilling to commit to submitting a $32 per share or higher offer to a vote of
shareholders, it is an insult to shareholders and another example of
management's self-interest to the detriment of shareholders. In this regard, Mr.
Icahn noted that senior executives of VISX cashed out nearly $100 million in
stock options in 1999 at share prices substantially above the recent stock
price, in addition to receiving their substantial compensation packages.

Ms. Elizabeth Davila, Chief Executive Officer
VISX Incorporated
3400 Central Expressway
Santa Clara, CA 95051

Dear Ms. Davila:

I was happy to read in your April 18th press release that you are "receptive" to
proposals for VISX. If you were not being disingenuous in your statement, then I
would like to make the following proposal: I would be willing to engage in a
cash merger with VISX, in which VISX shareholders would receive $32 per share,
subject to due diligence and financing.

Obviously due diligence with respect to a company like VISX, which involves
significant high technology assets, would require serious review and a
substantial commitment of money, time and effort. Also, obtaining necessary
financing for a transaction of this size would involve the payment of a
significant commitment fee. Therefore, I believe that if VISX management is
serious about receiving proposals, the Company should assure prospective buyers
which incur such upfront costs that if an offer is made it will be put to
shareholders for their approval.

If VISX agrees with me to submit to a vote of shareholders the best offer of $32
per share or higher from any qualified bidder, then I will be willing to commit
the significant funds needed to commence the necessary effort to conduct due
diligence and to attempt to raise the financing for the transaction. I have been
in contact with the Industrial Bank of Japan, a member of the Mizuho Financial
Group, and they are prepared to commence due diligence efforts immediately. If
the results of due diligence are acceptable, one of my affiliated companies
would provide a significant portion of the purchase price in order to effectuate
the offer, in addition to the funds to be derived from financing sources.

Naturally I cannot assure that my efforts will ultimately result in our
consummation of the transaction outlined above. However, it is my belief that in
any event my efforts, together with a clear commitment by VISX, may move the
auction process forward and bring out other potential bidders.

A price of $32 per share is more than 3 1/2 times higher than last year's
intraday low of $8.75 per share. If management is unwilling to commit to
submitting a $32 per share or higher offer to a vote of shareholders, it is, in
my view, an insult to shareholders and another example of management's
self-interest to the detriment of shareholders. In this regard, I note that
senior executives of VISX cashed out nearly $100 million in stock options in
1999 at share prices substantially above the recent stock price, in addition to
receiving their substantial compensation packages.

I await your reply!


Sincerely,


Carl C. Icahn

April 20, 2001


Dear Fellow VISX Shareholder:

As you are aware, I am conducting a proxy contest against the management of
VISX, Incorporated ("VISX" or the "Company") in which I am seeking to have my
five nominees elected as the directors of VISX. A proxy statement has previously
been sent to you. I hope you will support my efforts and vote for my nominees by
signing, dating and returning the enclosed WHITE proxy card which accompanies
this letter.

On April 20, 2001, I sent management a letter, a copy of which is attached for
your review, telling them that I would be willing to engage in a cash merger
with VISX, in which VISX shareholders would receive $32 per share for VISX,
subject to due diligence and financing, if VISX agrees with me to submit to a
vote of shareholders the best offer of $32 per share or higher from any
qualified bidder. Naturally I cannot assure that my efforts will ultimately
result in our consummation of the transaction outlined above. However, if VISX's
management commits to submit to a vote of shareholders the best offer of $32 per
share or higher, then I will be willing to commit the significant funds needed
to commence the necessary effort to conduct due diligence and to attempt to
raise the financing for the transaction. I have been in contact with the
Industrial Bank of Japan, a member of the Mizuho Financial Group, and they are
prepared to commence due diligence efforts immediately. If the results of due
diligence are acceptable, one of my affiliated companies would provide a
significant portion of the purchase price in order to effectuate the offer, in
addition to the funds to be derived from financing sources. I believe that my
efforts, together with a clear commitment by VISX, may move the auction process
forward and bring out other potential bidders.

A price of $32 is more than 3 1/2 times higher than last year's intraday low of
$8.75 per share. If management is unwilling to commit to submitting a $32 per
share or higher offer to a vote of shareholders, their action would, in my view,
be an insult to shareholders and another example of management's self-interest
to the detriment of shareholders. In this regard I note that senior executives
of VISX cashed out nearly $100 million in stock options in 1999 at share prices
substantially above the recent market closing price of $20.83 per share on April
19, 2001, in addition to receiving their substantial compensation packages.

DO NOT BE CONFUSED BY MANAGEMENT'S ACTIONS

VISX management may choose to ignore the interests of shareholders and reject my
proposal. They may, as they did in their April 18, 2001 press release, attempt
to justify their action by hiding behind their financial advisors, legal
representatives and the process that they have created for the review of
"strategic alternatives."





                                       5






Management is well aware that putting together a real bid for a company such as
VISX, which involves significant high technology assets, requires a great deal
more than merely contacting advisors. It involves due diligence activity, fees
for financing sources and lawyers and a substantial commitment of money, time
and effort. I can't imagine that a possible acquirer would undertake such an
effort merely for the privilege of having a conversation with Goldman, Sachs &
Co., especially in light of the fact that in January of this year VISX
management said that "the Company is not for sale." My proposal simply asks
management to agree that if a potential acquirer is willing to undertake all of
this expense and effort, management will confirm that they will allow
shareholders, the ultimate owners of VISX, to consider a bona fide, fully
financed offer at $32 per share or higher.


ICAHN PLATFORM

My platform is very simple and is explained in greater detail in the proxy
statement which should be carefully read by you. If my nominees are elected, I
will propose that the new board, subject to their fiduciary duties, consider the
following immediate actions:

1.      Conduct an open auction to sell the Company with a minimum acceptable
bid of $32 per share.(1) There can, of course, be no assurances that the auction
will achieve the desired result. Stockholders who do not wish to wait until a
successful completion of the auction may wish to sell their shares in a tender
offer as proposed in the next paragraph.

2.      Double the company's recently announced new share buyback program
from 10 to 20 million shares to be effected through an immediate issuer tender
offer by VISX at $25 per share rather than wait to make open market purchases
over a potentially long time period. If the Company is unable to obtain outside
financing to purchase the additional 10 million shares, I would lend the company
sufficient funds to do so on commercially reasonable terms. Furthermore, neither
I nor any of my affiliates would sell shares in the tender offer.

In the event no sale, merger or other business combination occurs, I would
propose that the new board consider, subject to their fiduciary duties:

----------------
(1) As stated in my proxy material, in selecting a minimum acceptable bid of $32
per share, I do not intend to be providing a valuation of VISX. However, in
selecting that minimum acceptable bid, I studied and analyzed the recent
acquisition of VISX's competitor, Summit Autonomous Inc., by Alcon Holdings Inc.
I also studied and analyzed the market valuation of Allergan, a company in the
ophthalmic field, and considered that according to VISX's 10-K, VISX is "a
worldwide leader in the development of proprietary technologies and systems for
laser vision correction." However, I pointed out that Summit, Allergan and VISX
have differences in revenue sources, product mix and financial resources, among
others, that affect their comparability. While a vote for my nominees is not a
vote to sell the Company, I will strongly urge that my nominees for the Board of
Directors of VISX consider, subject to the exercise of their fiduciary duties,
my recommendation to vote in favor of the sale of the Company at a minimum price
of $32 per share. It is expected that stockholders will be required to
affirmatively approve any sale of the Company.

                                       6






Forming an executive search committee to review existing management and consider
top-flight executive candidates. I believe that VISX's management has made a
number of bad decisions, which I consider to have turned out less than
beneficial to the Company. These include allowing VISX's relationship with TLC
Laser Eye Centers ("TLC"), the Company's second largest customer, to deteriorate
to the point where TLC announced that it has adopted technology provided by
Alcon and not VISX as its primary platform in its refractive centers. In
addition, I believe that management's decision to cut procedure fees in February
2000 from $250 to $100 per procedure is an important contributing factor toward
the decline in VISX earnings for the first quarter of 2001 as compared with the
first quarter of 2000. Finally, I disagree with management's decision to settle
a patent dispute by licensing VISX's proprietary technology to Bausch & Lomb, a
much larger company with substantial financial resources and, therefore, a
potential major competitor. Management has not disclosed the license terms.


MANAGEMENT SELF-INTEREST AT SHAREHOLDER EXPENSE

While management's decision making has not been satisfactory in my view, I do
have to credit them for their uncanny market timing and shrewd negotiation with
the existing board's compensation committee:

       Senior executives cashed out nearly $100 million in stock
       options in 1999 at share prices substantially above the recent
       stock price before announcing a dramatic cut in procedure fees in
       February 2000.

       After this "well-timed" massive insider selling not one
       member of senior management or the board of directors owns more
       than 50,000 shares other than via options which they have been
       granted.

       The top five executive officers received total compensation, including
       cash and options, valued in excess of $6 million (according to
       management's 2001 proxy statement) in a year in which shareholders
       suffered a decline in the company's share price from $52.10 per
       share in January 2000 to $10.44 per share as of year end.

Is this management team, which has unloaded most of its equity interest in the
company and been handsomely compensated while the share price has performed
poorly, dedicated to do what is in the best interest of shareholders?


MY CHALLENGE TO VISX

On April 18, 2001, I sent management a letter, in which, among other things, I
challenged them to conduct an open auction for VISX and agree to submit for
shareholder approval the best offer at $32 per share or above. Later that day,
in a press release and a letter to shareholders ("Management's Statements"),
VISX management responded to my letter. They did not agree to conduct an open
auction for VISX. Is VISX management unwilling to accept my challenge because
they are acting in shareholders' interests, or because they are concerned for
their own interests? I invite you to draw your own conclusions. In my view
Management's Statements continue a pattern of disingenuous and incomplete
statements by management.

                                       7






MY RESPONSE TO MANAGEMENT'S STATEMENTS

         Management says:
                  "We have already engaged in a review of our strategic
         alternatives with our outside financial and legal advisors. We and our
         advisors have contacted a number of companies in the ophthalmic and
         non-ophthalmic industries about possible sale, merger or business
         combinations. Based on our discussions, we do not believe that there is
         a currently available transaction that would enhance stockholder
         value."

         My view:
                  VISX management stated in its January 17, 2001 conference call
         that "the Company is not for sale". How then, are shareholders to
         believe that VISX management has fully reviewed all currently available
         transactions? By talking about "strategic alternatives" is management
         just paying lip service to the concept of stockholder value? In my
         experience, an open auction provides a solid opportunity for
         shareholders to receive an attractive value. By contrast, hiring
         high-priced outside advisors to review "strategic alternatives" can
         result in an open-ended process with no foreseeable benefits or exit
         date for VISX shareholders.


         Management says:
                  "VISX's earnings were $0.21 per share, exceeding expectations"

         However, management fails to point out that:
                  First quarter earnings per share declined 30% year over year,
         from $0.30 in 2000 to $0.21 per share in 2001. While first quarter
         earnings of $0.21 per share exceeded analysts' most recent estimates,
         those estimates had already fallen.


         Management says:
                  "VISX's industry-leading market share increased"

         Analyst views:
                  According to an April 16, 2001 J.P. Morgan H&Q report, VISX's
         procedure market share in the first quarter of 2001 was 68%, up from
         the fourth quarter of 2000 but down from 73% in the first quarter of
         2000. According to an April 16, 2001 Robertson Stephens report, VISX's
         procedure market share in the first quarter of 2001 was 63%, down from
         64% in the fourth quarter of 2000 and down from 67% in the first
         quarter of 2000.


         Management says:
                  "VISX's licensing revenue grew by 23% over fourth quarter,
         2000"

         However, management fails to point out that:
                  First quarter licensing revenue declined by 32% from the first
         quarter of 2000.



                                       8





         Management says:
                  "VISX's systems sales grew by 29% over fourth quarter, 2000"

         However, management fails to point out that:

                  First quarter system sales declined by 14% from the first
         quarter of 2000.


         Management says:
                  "If implemented, this [Mr. Icahn's] proposal would force VISX
         to assume $300 million in debt to finance a 20 million share buy-back
         program, thereby: immediately diluting VISX's earnings per share;
         severely weakening VISX's balance sheet; and depriving VISX of the
         flexibility to invest in essential research and development."

         The Simple Math:
                  I believe my share buyback program would increase the
         attractiveness of VISX to a potential acquiror willing to pay my
         proposed minimum price of $32 per share, since 20 million shares would
         already have been repurchased at a lower price. In addition, based upon
         year 2000 results, VISX had net operating income of approximately $74
         million after deducting $15 million of research and development
         expenses.(2) If VISX borrowed the additional $300 million referred to
         in Management's Statements and even assuming an interest rate of 11%,
         total annual interest cost would be $33 million. Therefore, after
         payment of interest VISX would still have $41 million available for
         additional research and development and other corporate purposes, AND
         SHAREHOLDERS WOULD HAVE RECEIVED AN AGGREGATE OF UP TO $500 MILLION
         FROM VISX.


TIME FOR A CHANGE

I believe management should be held accountable for their poor performance and
questionable decision-making. IF MANAGEMENT IS UNWILLING TO COMMIT TO SUBMITTING
A $32 PER SHARE OR HIGHER OFFER TO A VOTE OF SHAREHOLDERS, THEIR ACTION WOULD,
IN MY VIEW, BE AN INSULT TO SHAREHOLDERS AND ANOTHER EXAMPLE OF MANAGEMENT'S
SELF-INTEREST TO THE DETRIMENT OF SHAREHOLDERS.

I urge you to sign, date and return the WHITE proxy card in the enclosed
