The Lasers

Laser Vision Correction uses a laser called an excimer laser to resculpt the cornea of the eye.  In the United States, laser vision correction received approval from the FDA in October 1995. There are a number of different laser systems that have received approval from the FDA for laser vision correction surgery.
