Yacov, regarding Lasik and Epi Lasik, being young is a good thing. All that's necessary is for your eye prescription to be stable for a few years. The doctors will do all kinds of tests to determine if you are good candidate for the surgery. They will test for the shape of your cornea, and its thickness, among other things. Also if you are a diabetic, or have glaucoma, you would not be a candidate for the procedure.
In my case, I was nearsighted. And now my vision is 20/15. But when I get older I will need reading glasses, as it will be more difficult to see things very close to me. It happens with everyone. Some doctors encourage patients to leave one eye a little less corrected to compensate for this. But I decided against it. As I see it, if I'm going to have this surgery, I want my vision to be perfect. And now that I no longer wear contacts, my eyes are no longer dry.
