Laser-assisted in situ keratomileusis (LASIK) is a safe, reliable and painless way to improve vision by changing the way light is bent, or refracted as it passes through the cornea, so that it properly focuses on the retina and allows objects to be seen clearly.
During the LASIK procedure, the surgeon creates a thin flap in the surface of the cornea with a device called a microkeratome blade or with a laser. This procedure is performed under local anesthesia so that pain is minimized. The corneal flap is then lifted and an excimer laser beam reshapes the cornea's curvature to improve vision. Finally, the flap is closed and covered with a protective contact lens. The entire procedure takes about 15 to 30 minutes per eye.

Photorefractive keratectomy (PRK) uses an excimer laser to remove a small amount of the top of the cornea. Instead of cutting a flap into the cornea with a blade, 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 surgeon also has greater control in the location and amount of tissue being removed, allowing patients to enjoy a much more accurate treatment.
