Excimer Lasers for LASIK Surgery

Excimer lasers are used in LASIK surgery to reshape the cornea in order to improve eyesight. Hundreds of thousands of U.S. patients undergo LASIK procedures each year, and to date FDA has approved more than 30 excimer lasers for LASIK. But risks of the procedure include permanent loss of vision; dry eyes; glare, halows, starbursts in vision; and reduced vision in dim-light settings; and need for repeat treatment, according to the agency.

Activists Say:

The fact that retreatments are commonly performed after LASIK speaks to lack of efficacy of the first LASIK procedure, and adds to an already vast body of evidence that use of excimer lasers for LASIK never merited FDA approval.”

Industry Says:

LASIK has been shown to be a safe and effective procedure for the correction of refractive errors by numerous studies around the world. It has a low complication rate that is acceptable to many patients and comparable to that of contact lenses over a lifetime. ”
