PRK Laser Vision Correction Surgery

At Mercy Clinic Eye Specialists, we provide advanced laser vision correction while protecting your eye health. Studies have shown PRK has fewer risks than LASIK and is the safest option for preserving healthy vision.

What is PRK?

PRK (photorefractive keratectomy) is a laser eye surgery that treats refractive errors (when your eye doesn’t bend light properly). PRK reshapes the cornea to improve light refraction and correct nearsightedness, farsightedness and astigmatism. Unlike LASIK, PRK doesn’t create a flap in the cornea, so it eliminates the risk of the flap becoming dislodged and needing corrective surgery.

How Is PRK Performed?

At Mercy Clinic Eye Specialists, the iDesign Refractive Studio System helps our team deliver a truly personalized PRK procedure and the most effective results. The procedure involves the following steps:

1. Precise Planning – Much like a satellite map, guidance technology is used to create an intricate map of your eye that reveals the unique way it processes light. More than 1,200 measurements are taken of the inner and outer eye, and data points are mapped to create a customized procedure plan within seconds.
2. Customized Laser Treatment – Using your customized procedure plan and eye map, an ultra-precise laser gently reshapes the cornea so that it uses light more effectively. The procedure takes only a few minutes and includes several technology advancements that improve treatment accuracy.
3. Optimal Vision Improvement – When your procedure is complete, you’ll immediately notice the difference. More than 90% of our patients at Mercy Clinic Eye Specialists have 20/15 vision or better after receiving PRK. Careful planning, customized treatment and good post-procedure care are essential to achieving these results.
