PRK (Photorefractive Keratectomy)
If you choose to undergo PRK at Nationwide Vision’s Laser Center, you and your eyes will be taken excellent care of. Generally, patients opt to have PRK to address nearsightedness, farsightedness, and astigmatism eliminating the need for corrective lenses and contacts. Our optometrists and ophthalmologists have performed thousands of successful Arizona PRK procedures and had the opportunity to improve the vision of countless patients since we opened our doors in 1985.
What Is PRK?
Like LASIK, PRK (photorefractive keratectomy) by reshaping the cornea using a laser. The main difference between PRK and LASIK is that in PRK the cornea’s entire epithelial (outer) layer is removed to expose the area and no flap is created.
Is PRK Best for You?
PRK is best for patients who are 18 or older, have mild to moderate nearsightedness, farsightedness or astigmatism, chronically dry eyes or thin corneas. It is also best for patients that have careers or hobbies that may cause impact to the eyes.
Does PRK Differ From LASIK?
Instead of creating a flap on the epithelial layer of the eye to access the procedure site, PRK involves scraping off the outer epithelial layer of the cornea. When the epithelial tissue on the cornea is removed, the entire stroma of the eye can be operated on, which cannot be accomplished with LASIK. Patients who have already undergone LASIK once or whose corneas are too thin to create a flap are ideal candidates for PRK. Recovery time for PRK is slightly longer than that of LASIK; however, the results of the procedure are the same.
