The cornea and lens combine to focus visual images on the back of your eye. When the overall shape of the eye or the curvature of the cornea is incorrect, visual images appear blurry and out of focus. Laser In Situ Keratomileusis (LASIK) is a surgical procedure that uses lasers to reshape the curvature of the cornea thereby eliminating most or all of the blurry images.
The goal of refractive surgery is to help reduce your dependence on eyeglasses and/or contact lenses. All the following must apply in order to be considered a candidate for LASIK surgery:
- You must be 21 years of age.
- You must have a stable eyeglass prescription for at least 12 months.
- Your cornea (the tissue on which the laser is done) must be healthy and thick enough for the procedure
- Certain medical conditions and medications may disqualify you as a candidate
- You are not pregnant or nursing
