The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most patients, LASIK provides a permanent alternative to eyeglasses or contact lenses.

Doctors who are familiar with their patientâs unique vision correction needs can assist in the process of finding a qualified LASIK surgeon who specializes in a variety of special vision conditions.
