i know u from germany....
so since when the health fund company pays for an laser operation if you are younger than 18?
i even heard it cant be done for anyone younger then 20 or sth cause the eyes are still getting weaker / still changing. better do it after you full-grown.
if its free in germany you should do it ( if you dont have to be full-grown!! but i am sure you have to! )
another question is how about doing it in china/ whatever ... cause its freaking expensively in germany
€: checked google... ( yes its internet... better ask an doctor ^^ ) and the first 10 results telling "you got to be full-grown" --> at least 18 // +/-20
