PRK (Photo Refractive Keratectomy)

PRK (Photorefractive Keratectomy) is designed for the same purpose as LASIK.  In PRK, the thin outer layer of the cornea (epithelium) is removed and discarded prior to reshaping the underlying corneal tissue with an excimer laser. The epithelium repairs itself (grows back over the corneal surface) within a few days after surgery.

How PRK Differs from LASIK

PRK is very similar to LASIK with one exception. A corneal flap is not created at the beginning of the procedure. This eliminates a surgical step and eliminates corneal flap problems after the procedure. However, it also means that the individual must wear a set of clear contact lenses after the procedure while the cornea heals. Both procedures have similar success rates, and afterward, the need for corrective lenses on a daily basis is dramatically reduced or completely eliminated.

  • 18 years of age or older
  • Have a desire for permanent vision correction.

PRK with Dr. Epstein

The process for getting PRK vision correction always starts with a thorough evaluation of your visual acuity and glasses and/or contacts prescription. This is to determine if you have any eye diseases or eye health problems that may affect your current and future vision and to make sure your eyes are healthy enough to undergo the procedure. Your corneas will also be precisely mapped using state of the art technology to provide you with permanent, clear vision.

On the day of your eye procedure, you will be asked to arrive about an hour prior to the time of your procedure. During that hour, you will be given some medication to help you relax and prepared for procedure. The procedure takes just a few minutes per eye!

After PRK 

After PRK, you will have clear contacts in your eyes.  About 24 to 48 hours after your procedure, you will have a follow-up appointment with Dr. Epstein to make sure that your eyes are healing correctly. Between three and five days after your eye procedure, the contacts will be removed. Ten days after your procedure, your eye should be completely healed, and you should notice a significant improvement in your vision with maximum benefits occurring between three and six months after the procedure.
