I have had surgery in both eyes. After the surgery, I have 20/15 in my right eye and 20/20 in my left eye. I went through the surgery with just local anesthesia and could basically "see" while the Dr. removed my old lens and put in the implant. I opted for the simple correction and not the fancy variable focal implants, so I need to use reading glasses, but my far vision is great. I might add that I had worn glasses since about 7 years old and am now in my seventies and the last 3 years with good vision is surely a blessing.
The operation is basically uneventful and is done in a couple of hours. They only do one eye per session, for obvious reasons. I had another issue with my left eye that needed correction before my second implant, so a couple of months transpired between implants. My Dr. is now in N. Carolina, but he is great. I had gone to a very large eye clinic in Virginia and got very poor service and results there. A fellow worker directed me to my present Dr. and I cannot say enough good about him and his team.
Hope this gives you some insights.
