There are two types of procedures available: LASIK (Laser In- Situ Keratomileusis) and PRK (Photorefractive Keratectomy). In LASIK, a microkeratome is used to create a protective corneal flap. The laser is then used to reshape the cornea. When the procedure is completed the flap is closed.LASIK is an extremely effective technique, especially for higher degrees of myopia. Most doctors and patients are choosing LASIK over PRK due to the following advantages: faster visual recovery, less risk of corneal haze or scarring, reduced need for eye drops after surgery, fewer post-op visits, and the ability to treat a wider range of prescriptions.
With PRK, no scalpels are used and no incisions are made. The surface of the cornea, the epithelium is gently removed. By applying computer-controlled pulses of laser light to the surface of the cornea, the curvature is reshaped to match your prescription. This will allow the light to be properly focused by the eye. The laser vision correction procedure itself takes only a few minutes, and patients are typically back to work within three days.
