You are lucky you can use contacts. I honestly don't know if I would have had a corrective surgery if I could use contacts. My eyes are, however, so dry that I never found a brand of contacts that would stay in my eye for more than 2 hours. After that, the eye would be so dry that I would blink them out. The quality of eyesight isn't binary, though. The chance of total blindness from LASIK is, what?
