What is the difference between LASEK and PRK?

LASEK (laser epithelial keratomileusis) and PRK (photo-refractive keratectomy) are both advanced surface ablation procedures to correct vision by using the excimer laser to gently reshape the surface of the cornea. With PRK, the epithelium (skin layer of the eye) is fully removed and the laser is applied to the surface of the corneal tissue. During the LASEK procedure, the epithelial layer is lifted gently to the side and then replaced after the laser treatment. In each case, a clear bandage contact lens is placed over the cornea for 3 to 5 days to allow the epithelium to re-grow. Each procedure can be suitable for certain prescriptions and under certain conditions. Dr. Furlong will help you decide which procedure is best for you.
