Patients considering PRK (photorefractive keratectomy) laser eye surgery should be aware of potential side effects, including glare and halos, which are two of the most common side effects of PRK. Glare and halos can cause significant discomfort after PRK and can be difficult to manage. In this article, we will explore the causes of glare and halos after PRK, how to prevent them, and how to treat them if they do occur. PRK is a type of laser eye surgery that is used to correct nearsightedness, farsightedness, and astigmatism. During the procedure, the surgeon reshapes the cornea using a laser. The reshaped cornea focuses light rays on the retina instead of in front of it or behind it, improving vision.
While PRK has been found to be safe and effective for most people, there are some risks associated with the procedure. Glare and halos are two of the most common side effects of PRK. Glare is caused by light being scattered as it passes through the eye, while halos are caused by light passing around the edges of the cornea. Both can cause significant discomfort for patients, as well as blurry vision or difficulty driving at night. In this article, we will discuss the causes of glare and halos after PRK, how to prevent them, and how to treat them if they do occur. We will also explore how long these side effects typically last and what you can do to help manage them.
Are There Any Other Risks Associated With PRK?
In addition to glare and halos, there are other potential risks associated with PRK.These include dry eyes, infection, light sensitivity, night vision problems, and decreased vision quality. It's important to talk to your doctor about these potential risks before deciding whether or not to have PRK.
