I started wearing glasses in the 7th grade, back in the '70's, after my PRK in 1998, I discovered I needed safety glasses when I cut grass and run the weedeater. The regular glasses had protected my eyes and I had just got use to it. My vision was pretty bad, 20-250 and 20-300, with the PRK I went to 20-15 and 20-25, it was really neat to see my feet clearly in the shower. It's been 11.5 years and they've slipped to 20-25, 20-35, and my reading vision is not perfect anymore. After seeing my wife's operation, I'm not taking any chances!
Todd, keep getting your son regular check-ups and if you get a bad vibe, don't hesitate to get a second opinion, we did, and my wife finally got the excellant care she deserved.
