Also called lens replacement surgery, cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract, and its replacement with an intraocular lens. I've had both of my eyes surgery corrected for cataracts. Before, I had myopia (I could only see close up without glasses). Today, I can see far and almost near without glasses. I need dollar store reading glasses when I read small print. As I type this on my computer, I am not wearing any glasses at all.
