FOR IMMEDIATE RELEASE

IRIDEX Reports 2013 First Quarter Results

Profits Increase as Commercial Progress and Operational Streamlining Continue

MOUNTAIN VIEW, Calif., May 2, 2013 — IRIDEX Corporation (Nasdaq: IRIX) today reported financial results for the first quarter ended March 30, 2013.

• Ophthalmology revenues in the first quarter were $8.9 million, a first quarter record, compared to $8.3 million in the prior year period.

• Gross margin for the first quarter was 47.3%, compared to 48.0% in the prior year period. Margins were impacted in the quarter by strong international sales through our distributor network with a product mix favoring laser systems, which have lower margins than the Company’s consumable products.

• Operating expenses were $3.8 million in the first quarter which were reduced to $3.3 million as a result of the Company receiving $0.5 million in the form of a cash distribution from an insurance carrier. This compares to $4.2 million in the prior year period.

• Income from continuing operations for the first quarter was $0.9 million, or $0.10 per basic share ($0.09 per diluted share), compared with a loss from continuing operations of $0.3 million, or $0.03 loss per basic and diluted share, in the prior year period.

• Guidance for second quarter 2013: The Company expects to achieve revenues between $8.9 million and $9.2 million and gross margins between 47% and 49%. Operating expenses are expected to be between $4.0 million and $4.2 million.

CEO William M. Moore said, “We demonstrated good execution in the first quarter as the Company increased revenues and profits. In addition to these commercial and operational gains, we completed the successful product launch of TxCell™, our high speed scanning laser delivery system, and concluded negotiation of a beneficial selling and supply chain agreement with Peregrine Surgical. Of particulate note, the percentage of customers ordering new lasers with MicroPulse™ in the first quarter was approximately double that seen in last year’s period, giving us one more indication that we are edging towards a technology-driven tipping point in the market.”

Moore continued, “We will look to grow and increase profitability, invest in products that our customers want and that can be delivered to the market rapidly, and be opportunistic in acquiring or partnering with ophthalmic companies that have developed excellent technologies. Peregrine is a great example of such a partnership, as it allows us to market additional consumable products at different price points. The relationship should lower our supply chain costs and we are already, jointly, working on new product initiatives in the high-margin consumable product category.”

The preceding commentary relates to the results of the Company’s continuing ophthalmology business. In February 2012, the Company sold its aesthetics laser business and the financial statements reflect the results of its aesthetics laser business as discontinued operations.

Recent Business Highlights

• The Company entered into a global distribution and supply agreement with Peregrine Surgical, Ltd., a privately held company based in New Britain, Pennsylvania. Under the agreement, IRIDEX will become a worldwide distributor for Peregrine labeled products and Peregrine Surgical will become part of the IRIDEX supply chain for the manufacture of certain IRIDEX products.

• Following a fourth quarter 2012 FDA 510(k) CE clearance, the Company commenced its full commercial launch of its TxCell Scanning Laser Delivery System. This new product saves significant time in a variety of laser photocoagulation procedures by allowing physicians to deliver the laser in a multi-spot scanning mode, a more efficient method for these procedures than the traditional single spot mode. Management believes that the clinical and practice benefits of this technology will accelerate the adoption of the proprietary MicroPulse technology as it applies to several clinical procedures.

• February 28, 2013 the Board approved a new one year $3.0 million stock repurchase program.
