FDA Expands IntraLase FS30(TM) Laser Use to Include Penetrating and Lamellar Corneal Resections.

IRVINE, Calif. -- Global Innovator in Femtosecond Laser Technology Receives Industry's First 510K Clearance for Creating Corneal Resections Performed in a Variety of Therapeutic Procedures

IntraLase Corp. (NASDAQ:ILSE) today announced it has received a new 510K clearance from the U.S. Food and Drug Administration for use of the IntraLase FS30 femtosecond laser in creating the corneal resections performed in lamellar keratoplasty and penetrating keratoplasty procedures. The IntraLase FS30 laser is the first and only laser to receive clearance for use in penetrating keratoplasty.

For the first time surgeons can use the power and precision of the laser to complete resections in a wide variety of corneal therapeutic applications. The new clearance allows use of the IntraLase FS30 laser to create deep corneal incisions and the full-thickness resections required for penetrating keratoplasty. The Eye Bank Association of America estimates that more than 32,000 corneal transplant procedures were performed in the U.S. in 2004.

The new application of the IntraLase FS30 laser is the direct result of the company's ongoing collaboration with the world's leading corneal surgeons to develop innovative techniques with and enhancements of the technology.

"This really opens up the door for additional uses of this extremely versatile device," said Roger Steinert, M.D., professor and vice chairman of the department of ophthalmology at the University of California, Irvine, and president of the American Society of Cataract and Refractive Surgeons. "In our initial clinical work, we found that the laser has the ability to create shaped, full-thickness corneal transplants that are much stronger than traditional penetrating keratoplasty transplants with less induction of astigmatism. In addition, transplants created with the laser may require less suturing and faster visual rehabilitation."

IntraLase is developing commercially available software for these new applications as well as a new curved applanation lens to facilitate deep corneal dissections. The laser's current flat applanation lens provides the thin, planar flaps that have recently been shown to improve LASIK outcomes.

"This technology may have additional applications in the deep stroma, including Descemet's Stripping with Endothelial Keratoplasty (DSEK) procedures," said Francis Price, M.D., of the Price Vision Group in Indianapolis. "The laser's flat applanation surface provides very uniform and smooth anterior resections. But for deep stromal resections, a curved applanation provides a smoother interface. In the future, IntraLase FS30 will utilize both flat and curved applanation surfaces, providing the best solution for any application."

The IntraLase FS laser was commercially introduced in late 2001 as the first laser available for creating corneal flaps. The IntraLase laser is also cleared for anterior lamellar keratoplasty and intrastromal ring implantation surgeries, which like LASIK benefit from customized architecture and unsurpassed accuracy. As of June 30, 2005, 293 IntraLase FS lasers have been installed in refractive practices worldwide and approximately 18 percent of LASIK procedures in the U.S. used the IntraLase laser to create the corneal flap.

About IntraLase Corp.

IntraLase designs, develops, and manufactures an ultra-fast laser, related software, and disposable devices used to create a corneal flap, the first step in LASIK surgery for the correction of vision. The company's products improve the safety, precision, and visual results of LASIK procedures by providing a computer-controlled laser solution in place of the hand-held mechanical, metal-bladed microkeratome traditionally used to create corneal flaps. IntraLase lasers are also used in surgical approaches to the treatment of diseased corneas. The company's lasers and disposable per procedure patient interfaces are presently marketed throughout the United States and 21 other countries. IntraLase has headquarters and manufactures its products in Irvine. For additional information, visit the company's Web site: www.intralase.com.
