            VISX ISSUES STATEMENT RESPONDING TO ICAHN PROXY FILING


SANTA CLARA, CALIFORNIA, (April 11, 2003) - VISX, INCORPORATED (NYSE: EYE)
today issued the following statement in response to materials filed yesterday
with the Securities and Exchange Commission by Carl Icahn:

     The VISX Board of Directors and management team are taking the right
     steps to continue building value for stockholders. VISX is the undisputed
     leader in the U.S. laser vision correction industry, and we continue to
     deliver a solid operating performance:

     o   For the third year running, based upon industry data, VISX achieved a
         60% share of the U.S. laser vision correction procedures market;

     o   By closely monitoring our costs, we achieved 20% operating margins in
         2002;

     o   We generated over $40 million in cash from operations in 2002; and

     o   Over the past year, we repurchased nearly 4 million shares of stock,
         and we have repurchased approximately 20 million shares since we
         began our program in 1997.

     Our commitment to innovation is our commitment to the future. In 2002,
     following several years of development, we introduced CustomVueTM, a
     laser vision correction procedure that has the potential to improve
     vision beyond contacts and glasses. The results we are seeing from
     CustomVue in international markets have surpassed our expectations, and
     in the U.S., where we are awaiting FDA approval, over half of our
     customers are already equipped to perform CustomVue vision correction. We
     believe this approval will provide us with an extraordinary opportunity
     to gain incremental revenue and profit from VISX procedures and to
     reinvigorate demand for laser vision correction.

     VISX believes Mr. Icahn's 30-year-old Board nominee, an employee of one
     of Mr. Icahn's affiliate companies, lacks the relevant experience to help
     the company capitalize on these important opportunities.

     In stark contrast, the current Board of Directors is comprised of
     seasoned leaders who collectively have decades of experience in the
     medical and ophthalmic industry and significant mergers and acquisitions
     experience. Moreover,

     o   Six out of the seven Board directors are independent (VISX's
         Chairman, President and CEO is the only management director);

     o   All seven Board directors have experience serving on public company
         boards; and

     o   Six out of the seven Board directors hold or have held positions as
         Chairman, Chief Executive Officer, Chief Financial Officer or Chief
         Administrative Officer of a NYSE or NASDAQ listed company.

VISX is a worldwide market leader in the design, manufacture, and sale of
laser vision correction systems. Ophthalmologists have performed over 5
million procedures using VISX Systems, reducing or eliminating completely the
need for contacts or glasses. Additional information on VISX and VISX trained
and certified ophthalmologists can be found on the worldwide web at
www.VISX.com.
