What is PRK Surgery?

PRK all-laser, no-flap vision correction surgery is similar to LASIK because it utilizes the same exact laser technology to reshape your cornea and correct your vision. The primary difference is that with PRK surgery, the surgeon does not create a corneal flap, making this a single laser procedure. This is why it can be referred to as “no-flap LASIK”.

So, how does it work? Think of the cornea as a 500-page book. During PRK surgery the laser starts to correct the vision at the beginning of the book just below the cover, whereas during LASIK surgery, a flap is made first with a laser and then the same laser starts 50 to 70 pages below the cover.

During PRK surgery, using a very small gentle "brush", the corneal cover is painlessly removed in about five seconds. This cover is the skin layer of the eye that grows back quickly over several days. The cornea is then reshaped using our FDA approved state-of-the-art WaveLight EX500 laser.

If Dr. Mozayeni recommends PRK, it is because he is confident PRK all-laser, no-flap surgery is a safer option for you and will provide a long-lasting result. The most important thing to know is the end results after PRK are equal to those of LASIK.

PRK versus LASIK

Dr. Mozayeni recommends PRK surgery to approximately 25% of our patients due to one of the following reasons:

  • Corneal thickness is not adequate for creating a flap
  • Significant problems with eye dryness before the procedure
  • High risk for developing long-term dryness
  • The skin or cover of your cornea is already fragile or damaged due to age, previous injury, or previous infection
  • Unexplained corneal irregularity detected on your mapping
  • Significant scar tissue on the cornea
  • Your occupation or lifestyle is high risk for potential eye injury

Because Dr. Mozayeni is a cornea specialist, he is exceptionally capable of detecting subtle corneal abnormalities and recommending the safest, most predictable procedure for you. This is why meeting the actual laser vision correction surgeon and having a complete and thorough consultation is perhaps the most important part of your vision correction experience.

At Providence Eye, we have equally excellent results with LASIK and PRK surgery. In fact, our optometrist, Dr. Mills had PRK surgery performed by Dr. Mozayeni.
