Laser eye surgery under special circumstances?

Hello,

I'm 16 and have a visual impairment of -3.5 D on the left and -3.75 D on the right. I also believe I have slight astigmatism.

I want to have laser eye surgery because I'd like to join the German Armed Forces. Therefore, I'd like to have 18 lasers.

I read that you can have laser surgery from 18, but it's usually done at 24 or older because your eyes can get even worse again. For my intended use, I think the limit is 3, so it's okay for my eyes to get a little worse again. My ophthalmologist told me that with laser surgery, your eyes can get a maximum of 1 dpt worse. That wouldn't be a big deal.

If I explain it to the doctor like that, could he laser me?

By the way, my eye strength hasn't changed since 1.

Will 3,000 euros be enough for me?
