Overview

PRK (Photorefractive Keratectomy), is a kind of laser refractive surgery used to correct myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism.

It is a laser eye surgery for vision correction. PRK works by reshaping the cornea using an excimer laser, allowing light entering the eye to be properly focused onto the retina for clear vision without glasses and contact lenses.

In this procedure, the thin outer layer of the cornea (epithelium) is removed and discarded before reshaping the underlying corneal tissue with an excimer laser. The cornea repairs itself within a few days after the surgery.

Symptoms

This procedure is done when the patient suffers from refractive errors, such as:

  • Near-sightedness (myopia)
  • Far-sightedness (hyperopia)
  • Astigmatism (error in the shape of the cornea)
