I have had the operation in both eyes and my vision is GREAT. I don't even need glasses for distant vision. I am typing this without glasses and the screen is 2 feet away and I can see everything fine. I did get prescription glasses but the prescription was so mild I don't need to use them. I passed the driver license easily without glasses.
Note. You can view your cataract. I found out about this before the operation. Here how to view it. Take a piece of paper and punch a pin hole in the middle. Then go outside and look up at the bare blue sky. Look through the pin hole with each eye. The cataract will show as a fuzzy part of a round image of the pin hole. Do it with both eyes and you can see the difference between the clear and the cataract eye. Good Hunting... from Varmint Al
