“Can PRK cause cornea damage?”

By definition, of course it causes damage because you're basically removing the surface of the cornea using a laser. However, I think what you're asking is is this permanent and the answer is no not. Usually the healing process is usually about four days. Personally after doing a PRK, I will put on a bandage contact lens and the pain will be minimal. The healing will be 80% done within the first few days. It is useful for thin corns, where LASIK would not be recommended

- In rare cases, PRK carries long-term risks, such as over-correction, under-correction or vision regression, permanent dry eye, corneal haze, infection, scarring, and ectasia. Fortunately, these risks are rare but can cause permanent damage and vision loss. |   | | | Can PRK cause cornea damage? | | sent from my Google Glass Edwin Y.

Reactions to PRK can cause corneal scarring in some cases. Treatment with lubrication and mild steroids could reduce scarring as well as avoiding solar radiation.

Hello, I am not sure what you mean by this question. The process of reshaping your cornea with any laser, by definition, is damaging the cornea. If you are asking, it will damage your vision. Of course, the purpose is to improve your vision. Most patients will heal up just fine from PRK and have no complications. It is important, as in all refractive surgery, to have enough cornea left after the surgery to maintain stability. There are a lot of factors that go into that assessment. Just remember, this is an elective surgery.
