The full form for LASIK is Laser in Situ Keratomileusis, which in other words means the use of laser underneath the corneal flap of the eyes to reshape the cornea. In this procedure highly specialized laser beam or excimer laser is used to treat refractive errors and to improve vision. With such a treatment, the need for glasses or contact lenses is reduced or eliminated. Surveys show that about 92-98% of patients with eye problems are satisfied with the results of LASIK eye surgery.
