I classify any surgery by two criteria, those that are truly necessary and those that are generally said to correct some problem (think cosmetic surgery). I only opt for the first/truly necessary. If your eyesight is bad enough that it impacts your independence via driving, it sounds like you are in the "truly necessary" class.
What I learned through the course of my first cataract surgery is to very carefully vet the surgeon, and to pointedly ask him what percentage of his surgeries result in 20/20 vision; also, for those that don't result in 20/20, why? My current ophthalmologist represents that across the board 83% of patients achieve better than 20/40. I was shocked by that statement, but at the present I would kill for 20/40 or anything close to it in my left eye. Be your own advocate.
That's pretty simplistic, but in this case I will relate my own experience with cataracts.
I had a horrible cataract surgery experience in my left eye. I changed to a different ophthalmologist. In an earnest conversation with him, he stated that across the board 83% of patients achieve better than 20/40. I was shocked by that statement, but at the present I would kill for 20/40 or anything close to it in my left eye.

On a trapshooting forum I read countless accounts of amazing results with cataract surgery - good to know. I went ahead with the procedure, and the result was horrible. I changed to a different ophthalmologist. In an earnest conversation with him, he stated that across the field 83% of patients achieve better than 20/40. I was shocked by that statement, but at the present I would kill for 20/40 or anything close to it in my left eye. I have a rifle I built 3-4 years ago and it has never been sighted in for the simple reason that I can't shoot enough of a group at 25 or 50 yds to determine which way to move the sights. I'm waiting until
