Epi-LASIK is an alternative to LASIK – another way to have laser vision correction. It is very similar to LASIK except for one important difference. It creates a thinner corneal flap. This makes it a good option for people with thin corneas.
LASIK and Epi-LASIK are both ways to reshape the cornea, the clear front part of the eye. By reshaping its curvature, they cause it to bend light differently so that it focuses clearly on the retina. When the light-sensitive retinal cells (at the back of the eye) receive a clear image, they send it to the brain for interpretation and naming, and the brain can give you a confident translation of what you are looking at. This is 20/20 vision.
When a person has thin corneas LASIK may not be safe. Corneal reshaping is done by removing tiny pieces of tissue from the right places. This is not done from the top level of the cornea, but from the middle layer, the stroma. A flap of surface tissue is folded back to give the laser access to the stroma.
In eyes with thin corneas the flap needs to be thinner. The epi-LASIK flap is only as thin as the top layer, the epithelium – hence the name “epi”-LASIK. None of the stromal tissue is included in an epi-LASIK flap.
Results from this way of doing laser vision correction are every bit as good as those from LASIK or from PRK. You can read more on Choosing Between PRK and LASIK, as this page also discusses Epi-LASIK.
LASIK, PRK and epi-LASIK can all be done using Wavefront Technology for the diagnosis. This will give you better night vision.
