Considering refractive surgery? Here are some popular options:
PRK: Photorefractive Keratectomy, a more recent development in refractive surgery. This involves using a laser to remove outer layers of the cornea that ends in flatter shaped cornea. This procedure is appropriate for this with nearsightedness and astigmatism.
LASIK: Laser In Situ Keratomileusis, uses a laser to reshape the cornea but rather than removing the layers of the cornea, a flap is created with a special cutting instrument, the flap is then pulled back to expose tissue and a laser is used to reshape the tissue. LASIK may be acceptable for those with near or farsightedness and those with our without astigmatism.
LASEK: Laser epithelial keratomileusis, is a similar procedure to LASIK, however during the surgery a much thinner layer of your cornea is cut and folded back and then the flap is replaced. LASEK may be appropriate for those that aren't eligible for LASIK.
Please ask your doctor which refractive surgery may be right for you.
