I had bilateral PRK at Milton Keynes eight weeks ago now. My prescription was such, that I was advised that the outcome would be no different whether I had LASIK or PRK. I opted for the cheaper option, PRK, and the end result has been excellent. My eyesight is currently better than 20/20 and expected to be about 6/4 when I go for my 3 month check up. The only thing I will say is that PRK did not agree with me. Within an hour of the treatment I was in agony. It stayed like that for a couple of days and the pain killers given to me did not help very much. If you can afford it choose LASIK. That said, the aftercare treatment was very good and I am chuffed to bits with the final result.
