PRK - Photorefractive Keratectomy

PRK (photorefractive keratectomy) is a procedure that can be used to help people with mild to moderate myopia with or without astigmatism. During PRK, a special computer controlled laser (called an excimer laser) is used to reshape the surface of the cornea. The procedure itself takes just a few minutes, and you'll spend about an hour in the doctor's office or surgical center.

How PRK Reshapes Your Eye

PRK flattens the center of the cornea with a laser.

This is how the procedure is done:

  • Your refraction (glasses prescription) is entered into a computer, which calculates the amount and pattern of tissue to be removed.
  • The laser delivers a programmed number of pulses of ultraviolet light. Each pulse removes a microscopic layer of cornea from over the pupil, flattening the cornea.

When the center of the cornea is flattened, light rays are focused more directly on the retina and images are clearer.
