I'm definitely getting one. I don't have that much though (1.5 and 1.75), and the effects of the surgery are said to be permanent. You've to realize there's different doctors. I don't see how a person could possibly have worse vision after the surgery than before... could be personal reaction, or a bad doctor.
It is recommended you get the surgery at age 24 though since that's when the eye stops changing.. you can get the surgery starting at 18, but my optometrist said it'll be better if I wait till 24, which is why I haven't had it done yet.
I don't like my contacts much, so I can't wait
(Oh and, personally, my uncle had the surgery a long time ago and his vision is still perfect.)
