What is Photorefractive Keratectomy?

Photorefractive Keratectomy (PRK) is a type of laser eye surgery designed to correct refractive errors by reshaping the cornea, improving how light enters the eye to focus on the retina. Unlike LASIK, PRK does not require the creation of a corneal flap, making it an excellent option for patients with thin corneas or those at risk of complications from LASIK. During PRK, the outer layer of the cornea (epithelium) is gently removed, and an excimer laser is used to reshape the underlying tissue to correct vision issues.

What Does Photorefractive Keratectomy Treat?

PRK is effective in treating several common refractive errors, including:

  • Nearsightedness (Myopia): Improves distant vision by reshaping the cornea to reduce focusing issues.
  • Farsightedness (Hyperopia): Helps patients see better at close distances by adjusting the corneal curvature.
  • Astigmatism: Corrects irregularities in the cornea that cause blurred or distorted vision.

This procedure is ideal for those who may not be candidates for LASIK due to thin corneas, dry eye, or other eye conditions. PRK is frequently chosen by individuals with active lifestyles or careers where corneal flap complications from LASIK could pose a risk.

  • No corneal flap: Reduces the risk of flap-related complications associated with LASIK.
  • Long-term vision correction: Many patients achieve lasting vision improvement after PRK.
  • Suitable for thin corneas: PRK is an alternative for those not eligible for LASIK due to corneal thickness.
  • Effective for a range of refractive errors: Corrects nearsightedness, farsightedness, and astigmatism.

Vision may be blurry for the first few days, with improvements occurring gradually over a few weeks. Full visual clarity is typically achieved within three to six months. After recovery, many patients enjoy clearer vision without the need for eyeglasses or contact lenses.
