I was 13 and 15 prescription. Didn't have enough cornea to remove more than about half, so I passed. But a few years later I needed cataract surgery - much better! Insurance paid for the whole thing, no complications, and I have 20/25 vision (the 25 was due to high blood sugar). Plus got 6 weeks off from work (they do one eye as a time and it takes two weeks for healing plus time to get an exam for new glasses - for reading).
