Epi-LASIK

What is Epi-LASIK?

Epi-LASIK allows us to save the surface layer of cornea instead of either removing it (PRK) or killing the cells (LASEK). Retention of the epithelial layer is reported to improve patient comfort, enhance healing and protect the eye from haze development.

During the Epi-LASIK procedure, a device called an "epikeratome" is used to mechanically separate, lift and retain the surface layer of the cornea in a sheet. After the laser treatment has been completed, this sheet of vital, intact tissue is repositioned back in its natural spot over the top of the cornea. A special contact lens is then placed on top of the eye during the short healing process. Therefore, Epi-LASIK allows the surgeon to save the surface layer of cells that would otherwise be discarded or sloughed off; replacing epithelium back in its natural position after the laser treatment.

How is it performed?

Epi-LASIK involves a device (epikeratome) with a special non-sharp blade called a separator. It is held on the eye with suction, and makes a pass across the eye to lift up the surface layer cells in a complete sheet.

Who is a candidate?

Almost anyone who is a candidate for standard LASIK is a candidate for Epi-LASIK but it is best for those with especially thin corneas or other corneal irregularities.

What can I expect after the surgery?

Usually, you will wear a contact lens for 3-5 days after the surgery. Vision will fluctuate over the first several days. You should be able to see well enough to watch television and do many normal activities. However, it may not be possible for you to work for 4-5 days. There can be some minimal to moderate discomfort of the eyes in the first day or two after the surgery. We will give you medicines to use to treat any discomfort you many have.

What are the risks?

The risks appear to be no greater than with LASIK. However, since this is a relatively new procedure, it is possible that complications could occur that have not yet been noted.
