                      IRIDEX EXPECTS LOWER THAN ANTICIPATED
                              FIRST QUARTER RESULTS

                         UPDATED GUIDANCE GIVEN FOR 2001

     IRIDEX Corporation (NASDAQ/NMS:IRIX) announced that it expects sales for
the first fiscal quarter ended March 30, 2001 will be approximately $5.6
million, $2.2 million less than expected for the quarter. As a result, the
Company expects a loss from continuing operations for the first quarter of 2001
to be between $0.16 and $0.20 per share. In addition, the Company expects to
take a one-time first quarter charge in connection with the discontinuation of
its scientific and industrial activities in its Laser Research segment.

     "The revenue shortfall in the first quarter of 2001 is primarily due to
three factors," commented Theodore A. Boutacoff, President & CEO of IRIDEX.
"First, the initial commercial shipments of the Apex 800 hair removal system did
not commence in the first quarter and are now planned for the second quarter of
2001. Second, sales of our ophthalmology infrared products were lower than
expected due to a combination of the weakening economic conditions in the United
States and uncertainties surrounding Medicare reimbursement for certain Age
Related Macular Degeneration (AMD) procedures using our products. Third, key
component supply difficulties delayed shipments of our DioLite and OcuLight GL
and GLx laser systems."

     Mr. Boutacoff continued, "This is the first quarter in 8 years in which we
will not be profitable. As a consequence, the Company is reviewing its cost
structure and will take appropriate actions consistent with its revised revenue
expectations. However, considering our impending launch of a new product into
the hair removal market, the overall outlook for our business is still good. As
such, we are expecting to maintain our headcount, but we will shift personnel
into operations with growth."

     The Company now expects initial commercial shipments of the Apex to occur
in the second quarter of 2001. The Company underestimated the time it would take
to certify and begin manufacturing the Apex 800. Shipments made during the first
quarter for market preference evaluation yielded very favorable responses from
physician users.

     Domestic ophthalmology bookings during the first quarter were approximately
25% lower than expected. The company believes that lower than expected
ophthalmology product sales occurred due to a combination of the weakening
economic conditions in the U.S. and uncertainties surrounding

Medicare reimbursement for certain AMD procedures. During the second half of
2000, the Health Care Financing Administration (HCFA) deferred reimbursement
decisions for Transpupillary Thermotherapy (TTT) and other AMD procedures to the
discretion of the medical directors for the local Medicare carriers. Favorable
coverage decisions from these local carriers have taken longer than expected.
The Company believes that the continued delay in Medicare reimbursement for
certain AMD procedures is further impacting order placement for IRIDEX products
used to perform these procedures. The Company is actively working with local
Medicare carriers to resolve this issue and expects favorable resolution late in
2001. We expect that the reimbursement issues and the economic downturn together
will negatively impact our U.S. ophthalmology sales for the balance of 2001, if
conditions do not improve.

     The Company experienced delays in shipping its green laser systems (such as
the DioLite 532 for dermatology and the OcuLight GL and GLx for ophthalmology)
due to a supply shortage of a key component. As a result, the Company closed the
quarter with an increased backlog for such products and related delivery devices
of approximately $500,000. The Company believes that sufficient quantities of
the component will be available during the second quarter to satisfy both the
first quarter backlog and the second quarter production requirements.

     The Company is discontinuing the scientific and industrial activities of
its Laser Research segment in order to better focus available resources on its
medical applications and products. Scientific and industrial product sales for
the first quarter of 2001 were insignificant. The Company expects to take an
expense charge for discontinuing the scientific and industrial efforts while
reporting first quarter results.

     Based on current business conditions, the Company is updating its guidance
for the second quarter and fiscal 2001 for continuing operations. For the second
quarter, the Company expects sales to be between $7.2 and $7.6 million with
approximately break-even earnings per share. For the year 2001, the Company
expects sales to be similar to fiscal 2000 and earnings from continuing
operations to be slightly profitable for the year. This guidance is preliminary
and will be updated in our first quarter earnings release scheduled for Tuesday,
April 24, 2001.
