Many people who are tired of wearing glasses or contact lenses seek the help of refractive surgeons. Refractive surgery improves vision by correcting refractive errors such as nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. A high percentage of patients enjoy 20/20 vision or better after their procedure.
Common refractive procedures include LASIK, PRK, LASEK, and refractive lensectomy (clear lens replacement or CLR)..
LASIK stands for laser-assisted in-situ keratomileusis. During the procedure, a thin flap is created on the cornea using a microkeratome or a femtosecond laser. This flap is then lifted, and an excimer laser reshapes corneal tissue to alter the way light enters the eye. The flap is then replaced. The entire procedure takes only 15-30 minutes per eye. Recovery time is also short, and improvement in vision can be seen within a day. Vision often continues to improve and stabilize for a few weeks.
