there are currently no eye doctors in the world that can tell if a lasik procedure was done on you or not unless you told them. my eye doctor has performed several procedures on air force candidates and they all pass the medical ( they never told they had it done) .
the whole story about "detection" is an urban legend,unless they corrected you from more than -12. of course you must make sure your eye doctor won't disclosed what he did with anyone and make sure your medical record won't show you used to have corrective lenses and then they magically dissapeared, and not try to do any kind of insurance claim. furthermore, you should get it done in europe if you can. lasik was approved there 10 years before any US surgeon got the FDA approval to start doing the procedure here,so not only do they have way more experience, is virtually untraceble
