I had it a couple of years ago and I too recommend it. For one thing I got tired of washing my hair with conditioner because I couldn't even read the stupid bottle labels in the shower. I didn't have to take anything for pain and don't remember having any. My eyes teared a lot the first few hours but I slept through most of that too becasue I had the tranquilizer. It was expensive but I would do it agaim.
Oh yeah, my vision was effected as I see slight halo's around lights but it isn't bad.
Do it!
