PRK – Photorefractive Keratectomy: PRK was the first laser eye surgery approved by the FDA and has been performed for over 15 years. PRK is a good option for patients whose corneas have an unusual curvature or are too thin for LASIK. PRK is also a better option for patients with moderately dry eyes. PRK can treat nearsightedness, farsightedness, and astigmatism.

Description of the PRK Procedure

PRK (Photorefractive Keratectomy) is a safe, viable alternative to LASIK for many patients. Clear Advantage Vision Correction Center uses the same Technolas 217z excimer laser to perform PRK as we do for LASIK and Zyoptix customized LASIK. In addition, our pre-operative evaluation for PRK is identical  to the evaluation process for other laser vision correction procedures including the use of Zywave wavefront sensing technology. The difference between PRK and traditional LASIK is that no flap of tissue is created prior to resculpting the cornea with the excimer laser.
