                  VISX AMENDS STOCKHOLDER RIGHTS AGREEMENT

         Permits An All Cash Tender Offer At Or Above $32 Per Share

SANTA CLARA, CALIFORNIA (April 26, 2001) - VISX, INCORPORATED (NYSE Symbol:
EYE) announced today that its Board of Directors amended the Company's
Stockholder Rights Agreement to make clear that the Board will not stand in
the way of an all cash tender offer at or above $32 per share.

Elizabeth Davila, Chief Executive Officer of VISX said, "This amendment to
VISX's Stockholder Rights Agreement underscores our commitment to enhancing
stockholder value. We believe that Carl Icahn's proposal to buy VISX is
disingenuous. However, if Mr. Icahn is sincere, our Board has provided him
the opportunity to take a fully-financed all cash offer at or above $32 per
share directly to stockholders. We are confident that stockholders will
recognize that this amendment further demonstrates the independence and
objectivity of our Board.

"We continue to see no benefit to stockholders in electing Carl Icahn and
his nominees. It is time to focus on the facts. We believe that Mr. Icahn
and his group pose a threat to the short and long-term value of VISX. His
proposal to auction the Company offers nothing new to stockholders and his
stated stock repurchase scheme, which would require the Company to raise
$300 million of new debt, would dilute earnings and restrict VISX's ability
to invest in the future," concluded Ms. Davila.

Stockholders are urged to support VISX and vote their GOLD cards in favor
of the VISX director slate and discard any proxy card mailed by the Icahn
group. For more information about how to vote for VISX's slate of director
nominees, stockholders can call the Company's proxy solicitor, MacKenzie
Partners, Inc. toll-free at 800-322-2885 or collect at 212-929-5500.

The Board's amendment makes the Rights Agreement inapplicable to the
purchase of shares of the Company's common stock on or prior to July 31,
2001 pursuant to a fully-financed, all cash tender offer for any and all
shares of the Company's common stock at a price of at least $32 per share.
This amendment requires that the number of shares purchased in the cash
tender offer must represent at least a majority of the Company's
outstanding shares on a fully diluted basis (excluding shares owned by the
offeror and its affiliates or associates). This amendment also requires
that as part of its cash tender offer, the offeror must agree to complete a
merger transaction promptly after the closing of the tender offer in which
all shares not purchased in the cash tender offer would be converted into
the right to receive an amount in cash equal to the price paid in the cash
tender offer. A copy of the amendment to the Rights Agreement will be filed
with the Securities and Exchange Commission shortly.
