I did it about 3 years ago.
BEST MONEY I EVER SPENT!
I had reaaaaaaally bad eyesight...
I had have some light sensitivity - wear sunglasses, halos - eventually went away and dry eyes. I did not know my eyes were dry, but they could see it. I had to use prescription drops, Restasis (I think) and it soon went away. They followed up with me for a little over a year.
I cannot say enough good things about it... changed my life since I had been wearing glasses and contacts since I was about 9.
