Advanced Surface Ablation Photorefractive Keratectomy (PRK)

Advanced Surface Ablation Photorefractive Keratectomy (PRK) uses an Excimer laser to gently and accurately reshape the surface of the cornea at the most anterior portion of the cornea stroma.  It's similar to LASIK, but no flap is created.

The patient goes home with a soft contact lens bandage over the eye for 3-5 days.  Visual recovery with PRK is about one to three weeks.  Statistical outcomes for PRK are equivalent to LASIK outcome statistics.

Most patients who are eligible for LASIK can have PRK.  This technique may be preferred for patients with thinner corneas or sever dry eyes.

  • Those patients who may not be eligible for LASIK may be a candidate for PRK
  • Creates less dry eyes
  • No flap
  • Great predictability and stability


  • May have episodes of moderate discomfort/pain for 1-4 days after surgery
  • Usually do not achieve optimal vision for several weeks
  • More healing response, low risk of developing scarring or "unsmooth" surface - typically will resolve in a few months

After anesthetic drops are instilled, the surgeon gently applies an alcohol-based solution to the surface of the eye in order to loosen the surface cells. Then, the epithelium is gently removed prior to treatment. The Excimer laser then modifies the shape of your cornea to eliminate the need for corrective lenses. A soft contact lens is placed on your eye immediately after your procedure to act as a bandage.
