The surgery tacked down the torn tissue to avoid further injury. Luckily, the damage is in a part of the retina that light doesn't hit, making it one of those many, many things that don't actually do anything useful but can wreck you if they fail. Intelligent design my ass. Which, if it had been intelligently designed, would be optimized for standing upright. But that's OK, because about half of my income comes from butts not working right because of the whole "walking on two legs" thing.

But yeah, I'm thrilled that the surgery is available and easy on me.
