I had mine done by Dr Robbins in Roch about 2 years ago.  If I had to do it over again, I would pay double.  I had horrible eyes, now they are 20/15.  Its well worth it, and I would go to someone near you.  Check ups, visits and so on.  I am very happy with the $2500 I spent.  No regrets what so ever.  (I also rec. a good pair of sunglasses, polarized)
