Had it done 2X to each eye, I was seriously blind, now @ 20/25 or so, no glasses for me.
Oh yeah, it blinded me for a week each time, something about corneas wrinkling when they got laid back down, I I still have discomfort in my left eye sometimes. The correction isn't as good as a good new pair of glasses, actually sort of like going to my previous pair of glasses as far as acuity, etc seem.
The amount of correction you'll prob need done is similar to mine, I was 20/400 or so too, you can expect multiple procedures to get to where you don't need glasses with the current technology.
I'd hold off for a couple of years if I were you, there's some techniques coming that are supposed to give nearly everyone 20/10 after the procedure.
