Epi-LASIK

Epi-LASIK is a type of refractive surgery, which is designed to reduce a person's dependency on eyeglasses or contact lenses. The name stands for Epithelial Laser In Situ Keratomileusis and it is a derivative of LASIK surgery. Unlike other forms of LASIK, Epi-LASIK involves the creation of a thin flap on the cornea's surface using a mechanized surgical instrument known as an epithelial separator.

Procedure

The Epi-LASIK procedure begins with the application of anesthetic eye drops to numb the eye. The surgeon then uses a precision instrument to separate a very thin sheet of epithelial cells from the rest of the cornea. This sheet is lifted to the side and the cornea is treated with a laser. This laser reshapes the cornea's curvature to correct the patient's vision. The epithelial sheet is then moved back into place where it adheres naturally and acts as a natural bandage while the eye heals.

Benefits

Epi-LASIK has several benefits over traditional LASIK. It eliminates the risk of corneal flap complications, reduces postoperative discomfort, and provides excellent visual results. It is particularly beneficial for people with thin corneas, dry eyes, or those who participate in contact sports.

Risks and Complications

Like all surgical procedures, Epi-LASIK carries some risks. These include infection, overcorrection or undercorrection, regression of the initial surgical result, and the development of corneal haze. However, these risks are relatively low and can be further minimized by following the surgeon's postoperative instructions.

Recovery

Recovery from Epi-LASIK is typically faster than with PRK or LASEK, but slower than with LASIK. Most patients can return to work within a few days, although it may take several weeks for vision to stabilize completely.
