LASEK (laser epithelial keratomileusis) is a laser refractive procedure to correct nearsightedness, farsightedness and astigmatism. LASEK is sometimes referred to as "Epi-LASEK." It involves removing the top layer of the cornea as a flap-like sheet before re-sculpting the cornea with the excimer laser. The epithelial sheet is then replaced on the surface of the eye and a soft contact lens is inserted for a few days following the surgery.

What is the difference between LASIK and LASEK?
In the LASIK procedure, an instrument called a microkeratome is used to create a protective flap of tissue. LASEK also involves the creation of a protective epithelial flap, but there is no microkeratome used. Instead, the tissue is loosened with a medical solution and then is carefully moved to the side for the laser portion of the procedure. After the laser procedure, the tissue is then repositioned and healing begins.

Why would I have LASEK over LASIK?
LASEK is a great option for patients previously turned down for LASIK because of thin or unusually shaped corneas. It is also a nice option for those patients who are uncomfortable with the microkeratome.
