My Mum had this some years back, sods law we were in Africa at the time!! Luckily some world renowned surgeon was at the hospital. She did get her sight, but with a certain amount of blurring and double vision, as she wears glasses she now has a slightly clouded lens in that side of the glasses to reduce this, and she has good enough vision for all normal purposes including driving. I understand it is a case of getting the surgery the sooner the better, so if there's any hint of fobbing her off, make sure she is very insistent on being done asap! My Grandad also had one and he never got much sight in that eye, but of course that was a very long time ago, hopefully the technology is better now! Means I go for frequent check ups!!!
