Photorefractive keratectomy, or PRK, is a type of laser surgery to correct visual issues such as nearsightedness and farsightedness. Before undergoing PRK, it is important to be aware of its side effects.
Significance
Although PRK does have a few side effects, it is a mostly successful surgery that can correct visual problems.
Time Frame
Unlike the newer laser surgery known as LASIK, people who undergo PRK take longer to reach the desired visual acuity. It might take three months after surgery until vision is entirely corrected.
Warning
Most patients experience slight eye discomfort and tearing for a few days after the surgery.
Effects
Almost always, people who undergo PRK experience light sensitivity for the first few days after surgery.
Potential
Other side effects, which can last up to six months after surgery, include seeing glare and halos around images.
