PRK (Photo-Refractive Keratectomy)
PRK was the first procedure performed using the Excimer laser. It corrects vision by reshaping the cornea. The difference between LASIK and PRK is that with LASIK a corneal flap is created and the laser is applied to the inner tissue of the cornea. With PRK, the epithelium (the outer skin of the cornea) is removed and a laser is applied to the surface of the cornea. PRK can be used to correct low to high levels of nearsightedness, farsightedness and astigmatism.
PRK is for those who:
- want to reduce or eliminate their dependence on glasses or contacts
- are over 18 years of age
- have had a stable eye prescription for at least one year
- have no health issues affecting their eyes
- have corneas too thin for LASIK
- have large pupils
The decision to have PRK is an important one that only you can make. The goal of any refractive surgical procedure is to reduce your dependence on corrective lenses. However, we cannot guarantee you will have the results you desire. The vast majority of our patients are extremely happy with their vision after PRK and can do most activities without dependence on corrective lenses.
PRK is a safe, effective and permanent procedure, but like any surgical procedure, it does have some risks. After PRK, almost everyone experiences some visual side effects.These visual side effects are usually mild and temporary and have a tendency to diminish over time. But there is a slight chance that some of these side effects won’t go away completely, including light sensitivity, glare and halos. Serious complications to PRK are extremely rare.
After a thorough eye exam, you and your doctor will determine if PRK is an option for you. If you are a good candidate, you will be given additional information about the procedure that will allow you to make an informed decision about whether to proceed. Be sure you have all your questions answered to your satisfaction.
