Epi-LASIK is an abbreviation for Epithelial Laser In-Situ Keratomileusis. This procedure is an advanced type of corneal surface ablation to correct nearsightedness, farsightedness and astigmatism. Epi-Lasik procedure is performed on patients having very high refractive error with thin cornea. In Epi-Lasik method corneal flap of 60 µ is created instead of 130 µ flap in conventional Lasik procedure. This gives the eye surgeon extra 70 µ to perform Laser Vision Correction on patients having very high myopia. After the epithelial flap is made, it is lifted and gently folded out of the way. An excimer laser is used, as in LASIK or PRK, to sculpt the underlying corneal tissue. Then the epithelial flap is placed back on the eye with a kind of spatula. A special contact lens is placed on the eye to keep the flap in place while it re-epithelializes. The contact lens protects the surface of the eye and allows the epithelial cells to grow back properly. After Epi Lasik procedure patient may experience pain, watering and blurred vision for 2-3 days.
