Epi-LASIK is a type of refractive surgery, which is designed to reduce a persons dependency on contact lenses and eyeglasses. The technique was invented by Dr. Ioannis Pallikaris, and it attempts to merge the desirable features of other major refractive surgery techniques, such as PRK, LASIK and LASEK. Epi-LASIK is believed to avoid risks associated with LASIK and offers improved postoperative recovery relative to PRK. In essence, Epi-LASIK is described as an advanced type of corneal surface ablation employed to correct myopia, hypermetropia and astigmatism.
Epi-LASIK differs from conventional LASIK. LASIK involves cutting a flap in the cornea with a microkeratome or laser to reveal the stroma (the middle layer of the cornea). On the other hand, Epi-LASIK entails the creation of a thin flap of corneal epithelium. The epithelium is gently separated from the underlying corneal layer without cutting quite the same procedure as what is followed during LASEK. However, as opposed to LASEK, Epi-LASIK does not make use of any alcohol solution to loosen and remove the surface of the epithelium.
Like LASEK, Epi-LASIK is more appropriate for patients who have thin corneas...
