IntraLase Releases Clinical Guidelines Supporting New Therapeutic Applications for INTRALASE FS Laser.

IRVINE, Calif. -- Guidelines Extend Use of Femtosecond Laser to Treatment Of Diseased Corneas

IntraLase Corp., (NASDAQ:ILSE) announced today that it has released preliminary clinical guidelines extending the use of its laser to new therapeutic applications, specifically, the treatment of diseased corneas. In a related development, a global team of corneal surgeons, expert in the field of therapeutic lamellar keratoplasty, has formed the IntraLase Lamellar Study Group specifically chartered to advance the use of the INTRALASE FS laser for therapeutic procedures.

The new guidelines will assist ophthalmic surgeons performing anterior lamellar keratoplasties, a procedure involving the replacement of patient corneal tissue that has become severely scarred or diseased. Up until this time, surgeons have relied upon hand-held scalpels to dissect diseased tissue with replacement segments obtained from donor corneas. INTRALASE FS lasers bring unsurpassed precision to this procedure by using computer software to match the exact shape of the removed and donated tissue segments.

A second therapeutic procedure, the use of intrastromal rings to treat a condition known as keratoconus, is also being addressed in the new guidelines which the company released to surgeons attending the IntraLase laser user meeting at the recent American Academy of Ophthalmology meeting in New Orleans. Keratoconus is a disorder characterized by an extreme steepening of the cornea. The INTRALASE FS laser enables surgeons to precisely create a pocket into which an intrastromal ring segment is inserted to correct for the steepness and flatten the cornea.

Both therapeutic indications have been granted regulatory clearance in the United States and the European Union. IntraLase is providing reimbursement information to surgeons electing to use the company's lasers for therapeutic purposes.

Robert J. Palmisano, IntraLase president and chief executive officer, stated, "While the markets for anterior lamellar keratoplasty and intrastromal ring implants are small in comparison to the market for creating corneal flaps, the added indications are significant because they demonstrate the broad potential for the company's femtosecond laser technology." He went on to say, "Both therapeutic indications incorporate the use of IntraLase's patented disposable patient interface and could therefore result in additional per-procedure revenue opportunities for the company."
