What is Epi-LASIK?
Epi-LASIK is a laser vision correction procedure designed to treat myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Unlike LASIK laser eye surgery, Epi-LASIK does not require the creation of a corneal flap. As a result, people with thin corneas or other conditions that could contribute to LASIK complications may be suited for the procedure.
Epi-LASIK Laser Eye Surgery
As in other laser eye surgery procedures, Epi-LASIK begins with the use of anesthetic eye drops to numb the eyes. An instrument called an epikeratome is then used to isolate a thin layer of tissue in the epithelium (the outer layer of the cornea). The epithelial sheet is moved aside and an excimer laser is used to carefully reshape the cornea. Once laser treatment is complete, the epithelial sheet is gently replaced and allowed to adhere with the aid of a special contact lens.
Following Epi-LASIK, patients usually experience improvements in their vision around the third or fourth day, with most patients being able to drive in about a week. Vision may continue to improve for a period of up to several months. While the recovery time following Epi-LASIK is somewhat longer than with LASIK, the procedure may produce fewer flap complications because it does not penetrate the cornea.
As with all surgical procedures, Epi-LASIK carries with it the potential for certain complications. Although rare, the following risks have been associated with the procedure:
- Under- or over correction
- Flap complications
- Glare, halos, and starbursts
Epi-LASIK complications occur only in a small number of patients and most can be corrected with a follow-up procedure.
As a means of laser eye surgery, Epi-LASIK offers many advantages. The following benefits have been reported in association with the procedure:
- Lower rate of dry eye syndrome
- Reduced incidence of flap complications
