I had PRK surgery almost 5 months ago and my vision peaked 2 months ago (20/15) and took a drastic turn and now I need glasses again. My astigmatism was 180 and my prescription was around -9.75 on one eye and -10 on another. When I saw my surgeon he said that I would need temporary glasses for 2 or so months and then at my year anniversary for the initial surgery, I would get an enhancement. Is this normal? Could I ever be a candidate for perfect vision or will this keep happening?
