LASEK (Laser Assisted in-situ Epithelial Keratomileusis)

LASEK(laser epithelial keratomileusis) is a laser refractive procedure to correct nearsightedness, farsightedness and astigmatism. LASEK is sometimes referred to as "Epi-LASEK." During this procedure, the surgeon:

  • Removes the top layer of the cornea as a flap-like (or epithelial) sheet before re-sculpting the cornea with the excimer laser
  • Replaces the flap-like sheet on the surface of the eye
  • Inserts a soft contact lens for a few days following the surgery

What Is the Difference Between LASIK and LASEK?

In the LASIK procedure, the surgeon uses an instrument called a microkeratome to create a protective flap of tissue. LASEK also involves the creation of a protective epithelial flap, but without the microkeratome. Instead, the surgeon loosens the tissue with a medical solution, carefully moving it to the side for the laser step of the procedure. After the laser procedure, the LASEK surgeon repositions the tissue and healing begins.

Why 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 an option for patients who are uncomfortable with the microkeratome or flap in general.
