Uh...Scepticalscribe, actually, Fooferdoggie has told us several times here (and also in posts on MR) that his wife is visually impaired -- blind -- and so of course she does not drive at all. The recent surgery is something new and experimental/clinical trial stuff to help improve her situation but my impression is that it wouldn't be expected to totally restore normal vision (if she ever had that at all). It's exciting, though, because this research and surgery can benefit not just her but many others to come along in the future, which is the whole point.
Cataracts....Sigh..... In a few more years I'll be doing the cataract surgery thing, as my right eye is slowly developing one....not sure why the left eye isn't also doing so, but whatever. NOT looking forward to the procedure itself but definitely will appreciate the outcome, assuming all goes well! Right now, thankfully, my vision is still good enough to be safely behind the wheel of a large moving vehicle but I know that the day will come when, with my ophthalmologist, I will need to schedule the surgery and pause driving temporarily until I have had the surgery and healed from that.
