However, like any other surgery, there are potential side effects that one should be aware of and must be able to accept a small amount of risk. Proper testing before the procedure can identify patients who are at a high risk for long-term risk for long-term complications. There maybe some visual aberrations such as – glare, double vision, ghosting, halos, starbursts, and problems with low-light or night vision, and experience dryness of the eyes. These are the more common side effects of PRK. Most patients experience some of these symptoms immediately after the surgery but they improve as they recover, so most require no treatment. Dry eyes This is fairly common and almost all patients experience some degree of dry and gritty feeling during the recovering period. This can be eased with the frequent use of lubricating eye drops. Night Vision Problems During the first few weeks or months, one might experience halos, glare and starbursts at night. This condition usually improves with time. Under-correction, over-correction, or astigmatism In some cases, corrective eyewear or contact lenses may still be required for the few activities which are more visually demanding. This can be due to the laser removing too little or too much tissue, or can be caused by variance in the way each eye heals after surgery. An enhancement procedure may be done in such cases. Other Risks exceptional to PRK Haze which is a diffuse scarring of the lasered cornea can cause blurring of vision in a few people but this can be prevented with medication and good UV protection after the surgery.
