Is lasik eye surgery a cosmetic procedure and not covered by insurance?

Not cosmetic; uncove. Lasik corrects the basic vision eliminating the need for eyeglasses and contacts. Since the outlay is large for a given period of time, and insurance companies are run by bean counting accountants, they prefer to pay for a little bit at a time for optical corrective devices and not the big amount for lasik which disturbs the quarterly report.
Yes. Yes. Lasik is cosmetic and not covered by insurance. A few insurances pay for a very small portion of the procedure but this is rare.
