Common Questions And Concerns About Photorefractive Keratectomy (prk)

Photorefractive keratectomyPRKis among the popular laser eye surgeries that people undergo to correct refractive errors and improve their vision. A popular procedure before LASIK burst onto the scene, PRK caters to patients who are not candidates for LASIK or who do not want to deal with the possible complications with the corneal flap. In addition, PRK has been the corrective laser eye surgery of choice for the US military.

Whats the difference between PRK and LASIK?

The LASIK and PRK procedures are very similar. The defining step for each is the first step. While LASIK is characterized by the flap that is cut from the surface of the cornea, the PRK procedure does not involve flap creation. Instead the top layer of the cornea is removed completely and the cornea is shaped with an excimer laser.

Who is a Candidate for PRK?

As with any laser eye surgery, the best candidates for PRK are patients who are healthy, who have a stable refractive error, and who have a realistic expectation of their results. Patients with a history of certain eye conditions may not be good candidates for PRK. Your refractive surgeon will be able to assess your candidacy for PRK and other vision correction treatments.

What are the Common Side Effects of PRK?

As with LASIK and other refractive surgeries, many patients report pain and discomfort following PRK, which gradually subsides after a few days. Though rare, complications associated with PRK include dry eyes, glare or halos, corneal haze, scarring, and reduced vision in low light situations.

Is PRK covered by Insurance?

Most insurance companies do not cover PRK, or any refractive surgery for that matter. However, you should contact your insurance company before your treatment to see what is and isnt covered. In addition, your vision correction center may offer its own financing for patients who qualify.
