Photo Refractive Keratectomy

What is PRK?

PRK (photorefractive keratectomy) is an outpatient procedure performed with topical anesthetic. The visual results are similar to LASIK, the main difference between PRK and LASIK is that in PRK there is no flap — only the very top layer of the cornea is removed before the surgeon reshapes the cornea with the excimer laser.

There are several reasons why a surgeon would recommend PRK rather than LASIK for an individual patient:

  • No concern about potential flap complications
  • If the patient’s corneas are too thin to meet LASIK standards
  • If the patient had LASIK previously
  • If the patient has dry eyes

The Procedure & What to Expect

In PRK, the surgeon removes the top layer of the cornea. Your eye will be numbed with a topical anesthetic to reduce discomfort. The surgeon uses the excimer laser to reshape the cornea, a “bandage” soft contact lens is used to promote healing of the cornea, which takes about four days. It may be a few weeks before your vision stabilizes, but visual outcomes of LASIK and PRK patients are similar.

Advanced technology to individualize your vision correction, CustomVue Wavefront technology is groundbreaking because it has the potential to improve not only how much you can see, but also how well you can see. With custom PRK, your eye’s ability to focus light is measured and a 3-D map is created that demonstrates irregularities. Information contained in the map guides the laser in customizing the treatment to reshape your eye’s corneal surface so that these irregularities can be corrected. Traditional PRK procedures cannot treat these irregularities.
