The last time I got a glasses prescription the doc told me I'd be a good candidate for the surgery because my vision has for the most part stopped getting worse. Still, my contact lens prescription is a year older than my glasses prescription and I can tell that it needs updating so I'm not so convinced yet. My vision is pretty bad, my prescription is around -7.00 diopter. So I'm gonna wait until I have some more evidence that my vision really is leveling out.
