Linda, I had cataract surgery on both eyes and I only need specs for reading.
But it is fairly common for the replacement lens to cloud over again. Just like having the cataract back!
The treatment is a laser procedure done in the doctor's office. The laser makes a wee hole in the lens and you can see clearly, more or less immediately.
I have had my right eye done a couple of years ago. now I have to get my left one fixed!
