Are there different types of LASIK procedures?
LASIK stands for Laser-Assisted in-situ Keratomileusis. There are 3 main varieties of LASIK surgery, only one of which is correctly called “LASIK surgery”, and it’s principally used for people who are very shortsighted or very longsighted. The other kinds are: PRK (Photorefractive Keratectomy), which was the original kind and is still sometimes used. It involves gently scraping some surface cells off the cornea and then using a laser beam to re-shape it. E-LASIK, or Lasek (Laser Epithelial Keratomileusis), which is used for people with mild to moderate short-sightedness, whose corneas are too thin and delicate for regular LASIK surgery. A finer blade is used to create a tiny flap from the epithelium of the cornea, but before it is lifted, an alcohol solution loosens the edges. Then the LASIK surgery re-shapes the cornea and the flap is replaced Epi-LASIK, (Epithelial Laser In-Situ Keratomileusis), which, like e-LASIK, is for those whose corneas are too too thin and delicate for regular
