Epi-LASIK is a variation of the more traditional LASIK and LASEK laser eye surgery procedures that attempts to combine the advantages of both. The purpose in its development was to minimize flap complications, promote faster healing, and better treat patients with very thin corneas.
Epi-LASIK (epipolis laser in situ keratomileusis) is similar in many respects to LASEK, in which an ultra thin flap is cut into the epithelium (outer layer of the cornea). The flap is then floated from the eye with a solution of alcohol. In epi-LASIK, a specially designed instrument called an epikeratome is used to both cut an ultra thin flap from the cornea as well as separate it. No alcohol is used in Epi-LASIK surgery, and it is believed that not using the potentially toxic alcohol solution may help promote faster healing.
After the flap is gently moved out of the way, the cornea is reshaped with the excimer laser as in traditional LASIK surgery. When the laser treatment is complete, the flap is gently replaced with a spatula-like instrument. A thin soft bandage contact lens will then be worn for several days to promote healing and lessen any discomfort.
Epi-LASIK offers an advantage to patients with very thin corneas, and it is believed that the recovery and healing process may be somewhat faster with this technique. The procedure in not suited for every patient. Based on your consultation, your eye surgeon will make the recommendation of which type of laser surgery is appropriate for you.
