To operate in myopia at age 18?!

I have 17 years and next year I want to have surgery, I have 3.50 diopters, the last 0.5 years I have been augmented because I wear glasses and contact lenses hurt me, I have used lenses from age 12 to 15, now I'm allergic to them. I know that at 18 years is not advisable to operate but I have a special interest in it because I get very embarrassed glasses and always ends quitandomelas when I go out, and people I know who greets me not reconozco.Practicamente it is certain that in 3 or 4 years and have myopia vuelba but after that it will take between 21-24 years to operate definitivamente.Que vuelberia me you recommend me?
