Laser Refractive
Laser refractive surgery, also known as LASIK, LASEK and PRK, uses a laser to remodel the cornea to eliminate short/long sighted issues and astigmatism.
LASIK (Laser-assisted in situ keratomileusis) is a procedure where a flap is created on the front of your cornea, and an excimer laser is used to remodel the cornea under the flap before re-positioning the flap in its place.
LASEK (Laser-assisted subepithelial keratomileusis) is a procedure where only the epithelial cells (front cells) of your cornea are loosened and moved to one side, before application of excimer laser to remodel your cornea. The loosened epithelial cell layer is then re-positioned on the surface of your cornea following the laser ablation.
PRK (photorefractive keratectomy) is a procedure whereby the front epithelial cell layer of your cornea is completely removed before excimer laser ablation. My
