LASIK is a safe, reliable and painless way to improve vision without the need for glasses or contact lenses. The procedure is effective for many patients with nearsightedness (myopia), farsightedness (hyperopia) and astigmatism.
Excessive, insufficient or uneven corneal curvature may be surgically corrected using LASIK, LASEK or other refractive procedures to improve vision and reduce or eliminate the need for eyeglasses or contact lenses.
Photorefractive keratectomy (PRK) is a unique laser vision correction procedure that uses an excimer laser to burn away a small amount (about 5 to 30 percent) of the top of the cornea in order to correct refractive errors. Instead of cutting a flap into the cornea with a blade like the LASIK procedure, this method preserves the strength of the cornea and avoids the risk of perforation and other flap errors commonly associated with the blade method.
During the PRK procedure, the eyes are numbed with anesthetic eye drops, before your doctor uses targeted laser energy to correct the shape of the cornea. The doctor has complete control over the laser throughout the procedure for highly precise, customized results designed to give each patient the best vision for their individual eyes. The entire procedure takes only a few minutes to perform in your doctor's office.
