You can get it done any time, so long as you are an adult.

I had it done and have 99.8% vision now. And the cornea for most people is thick enough to do the procedure twice over...it's not like it removes 90% of the cornea. And the cornea will work perfectly fine afterwards. There is a slightly bigger risk of permanent injury only if something scratched the eye badly. Oh, and your cornea is fully grown by age 15/16.

Not true unless you have some condition which is already causing your eyesight to deteriorate. Once you reach age 50-55, your eyesight does naturally start to deteriorate as well, although fairly slowly.
I'd recommend the procedure 100% if you have less than 85% vision. Painless, not even uncomfortable, and you should get practically perfect vision after it.
