What Is Photorefractive Keratectomy – PRK?

Dr. Swale began using the RK (Radial Keratotomy) method in 1992. Through growth, education and sophisticated method changes Dr. Swale continues today by exhibiting his expert knowledge in LASIK and PRK since 1998. The one thing that has not changed is that Dr. Swale’s vision on patient outcome has been to help patients see their best in the safest way possible.

Therefore, he now would prefer PRK (Photorefractive Keratectomy) over LASIK.

The Photorefractive Keratectomy Procedure (PRK)

The surgeon treats the corneal surface to correct Myopia, hyperopia and astigmatism. PRK gives the patient safer surgical options while still providing the same laser technology and outcomes as LASIK.

The PRK Laser is used to gently remove the outer layer and to reshape your cornea.

This procedure avoids the cutting of a flap on the corneal tissue which in return minimizes potential flap complications in the future. The cutting of the flap also increases the risk of intraoperative complications. It can also cause increased dryness in patients who already have dry eyes before the procedure.

How LASIK is different from PRK

A small flap of corneal tissue is created using a laser then folded back to allow for reshaping.

LASIK was the next generation of vision correction reducing the amount of post-surgery discomfort. Because of this flap, there is a potential for flap related intraoperative and post-surgery complications including severed nerve endings, microscopic wrinkles, irregular astigmatism, inflammation and dry-eye syndrome.

Supporting Cases: The Flap Never Fully Heals

  1. A patient involved in a car accident 8 years after LASIK surgery has the cornea flap pushed off the eye by the air bag.
  2. A patient who accidentally hit themselves in the eye while removing a snowmobile cover knocked the LASIK flap off the eye.
