What is PRK Laser Eye Surgery?

Answer:
PRK stands for photorefractive keratectomy

and is a type of laser eye surgery used to correct long-sightedness, short-sightedness, and astigmatism. It involves reshaping the cornea by removing tiny bits of tissue from the surface with an excimer laser which uses a cool, ultraviolet light beam.

Once re-shaped, the cornea is better able to focus light onto the retina, providing clearer vision. PRK surgery used to be the most common form of refractive surgery (surgery that’s performed to correct vision, reducing or eliminating the need for glasses or contacts). PRK surgery is preferred for patients with thin corneas or large pupils.
