None of my boys had it, but my right eye started turning in when I was 20. Things got worse and worse, and I finally had surgery when I was 27. My surgeon is Dr. Marilyn Mets, who runs pediatric opthalmology at Children's Memorial Hospital. The operation was a breeze (and I had it at Children's, so I can attest to how wonderful their nursing staff is!). It was outpatient surgery with very little residual pain. That night, I was able to see with single vision for the first time in my life, which was pretty amazing.
I actually had to repeat the surgery when I was 32 or 33, because I'd taken a blow to the head in a car accident and I started seeing double again. Dr. Mets did it again (at Northwestern this time), and she did an awesome job.
I don't know if this helps you at all, but I know how scary it is to have your child go through a medical procedure -- at least you can hear from someone that it didn't hurt and the results were great!
