I lost my right eye when I was five due to retina detachment. Long story short and thanks to doctors from Dallas to Boston, not only was my right eye saved, but I have 20/20 vision with no line trifocal glasses and a lens implant. Two retina surgeries decades ago, one cataract surgery 15 years ago, glaucoma laser procedures several times. Five drops a day. Not to mention macular degeneration. If it weren't for my eye(s), I would have never spent a single night in a hospital. So far as the cataract surgery, it was a breeze, and you will see better immediately. I don't drive much at night due to the implant causing multiple halo's around every car and street lamp.
