If it were me (and I do have one with this issue), I would not have the surgery. They do just fine with the loss of sight.
Yes, this has been noted in many gliders in the past. There isn't much info on it on the boards, though there is at least one other thread here on TSS about cataracts. I guess that is because most people don't do much more than monitor it. Gliders live for years with cataracts with no other issues.
