What is the PRK Procedure?

Last updated 2 years ago

PRK, which stands for photorefractive keratectomy, is a similar form of corrective eye surgery to the more commonly-known procedure called LASIK. Like the LASIK procedure, PRK uses a laser to reshape your cornea to correct nearsightedness, farsightedness, or astigmatism. During PRK, a laser sends a beam of UV light onto the surface of the cornea. During LASIK, however, the laser beam is directed underneath the cornea. While the two methods only differ in this slight change of laser direction, it spawns noticeably different results for patients post-surgery.

To learn more about the PRK procedure, read the following overview:

  • Advantages: PRK patients experience a high rate of vision enhancement. Around 80% of patients achieve 20/20 vision a year after surgery, without having to depend on corrective lenses. Surgeons also prefer PRK when treating patients who have very thin corneas. In general, PRK tends to be a safer alternative to LASIK because it does not require cutting the corneal flap. This reduces the risk of complication during surgery.
  • Drawbacks: Unlike LASIK surgery, which typically provides immediate vision improvement, PRK patients undergo a longer recovery period. Patients will notice their vision improve gradually over three months. They are also more likely to experience discomfort and irritation in their eyes immediately following the surgery.
  • Long-Term Results: Both PRK and LASIK patients can expect similar outcomes in vision correction over a period of time. That being said, it is also true that patients of either procedure are subject to individual experiences that may require the use of glasses or contacts in the future. Presbyopia, which tends to hit people in their forties, is a condition that can impede any type of laser eye correction.
