LASIK is available in 2 different yet safe methods–flap and flapless LASIK. If you choose (or your surgeon recommends) to undergo flap LASIK, the surgeon will cut a flap in your cornea with the laser to reshape the mid- cornea prior to folding back the flap, which heals almost immediately. Flap LASIK causes slightly blurry vision and achiness for up to a few days. While flap LASIK has the fastest healing time, Dr. David Shapiro a board-certified ophthalmologist from California, says this surgery has the most associated complications due to tears, wrinkles, and infections.
Flapless LASIK requires no cut. Instead, the surgeon will remove a microscopic, clear layer of the epithelial that’s no thicker than a hair to laser the cornea directly. Flapless LASIK may cause more eye irritation and a longer healing time. However, according to Dr. Shapiro, the epithelial is the fastest replenishing human tissue and less complications arise from flapless LASIK.
