PRK stands for Photorefractive Keratectomy. It's another laser vision correction procedure, but instead of creating a corneal flap like LASIK does, PRK works on the surface of the cornea. We gently remove the outer layer of cells and then use the laser to reshape the cornea underneath. The outer layer grows back naturally over a few days. For people with thinner corneas who aren't candidates for LASIK, PRK is a fantastic alternative that gives the same excellent vision results.
PRK has a slightly longer recovery than LASIK, but most people are very happy with the process. Your vision improves gradually over about one to two weeks. Your surgeon will prescribe special eye drops to help with comfort and healing. You'll need to protect your eyes from sun and avoid strenuous activity during the healing period. Some people experience mild discomfort or haziness during the first few days, but this is temporary and manageable. By the end of the healing period, your vision is just as sharp as it would be with LASIK.
PRK is perfect for people with thin corneas who can't have LASIK. It's also great for athletes or people involved in contact sports because there's no flap to worry about. PRK works for nearsightedness, farsightedness, and astigmatism, just like LASIK. If you have a stable prescription, are in good eye health, and have the patience for a slightly longer recovery, PRK might be your best choice. Our surgeons will evaluate your corneal thickness and help you decide if PRK or another procedure is right for you.
The final vision results from PRK are essentially the same as LASIK. Once your cornea heals, you have permanent vision correction. The difference is just the recovery timeline. Most people are back to their normal routine within one to two weeks. PRK has been performed successfully on millions of people worldwide with excellent safety outcomes. Serious complications are extremely rare, and most side effects like temporary dryness or light sensitivity resolve quickly as your eyes heal.
