Epi-LASIK
Epi-LASIK
Epi-LASIK (pronounced: epi-lay-sik) is a type of refractive surgery that is used to correct myopia, hyperopia, and astigmatism. The term "Epi-LASIK" is derived from the Greek words "epi", meaning "upon" or "over", and "LASIK", an acronym for "Laser-Assisted In Situ Keratomileusis".
Procedure
In an Epi-LASIK procedure, a thin flap of the cornea's surface (epithelium) is separated from the underlying tissue. This is done using a mechanical device called an epithelial separator. After the flap is lifted, an excimer laser is used to reshape the underlying corneal tissue. The flap is then repositioned on the cornea without the need for stitches.
Advantages
Epi-LASIK has several advantages over traditional LASIK surgery. It eliminates the risk of flap complications, reduces the risk of dry eye syndrome, and is suitable for patients with thin corneas.
Risks and Complications
Like all surgical procedures, Epi-LASIK carries some risks. These include infection, inflammation, and problems with the flap, such as displacement or wrinkling. Some patients may also experience changes in vision, such as glare, halos, or double vision.
