Should I consider undergoing a third PRK laser eye surgery? What are the risks involved?

Well I'm going to make this simple this would be my 3rd prk enhancement surgery for my right eye if I decide to get it done currently my right eye is+0.50 I had it overcorrected I'm debating weather I should get another prk enhancement surgery because it's a little bit of a hassle. What are some risks that might be not worth it or anything that I should know I've read tons of bad surgery reviews and mine isn't that bad but I think I need more about risks or anything.
