If you get a cataract, spend the extra money on a CrystaLens. Unlike 45 year old natural lenses and implants available before 2003, they will actually focus. Of course they're under patent so they're about a thousand dollars each more expensive than other implants. I'm sure I'll have a cataract in the other eye not too long from now, the last eye doctor I saw said "a couple of years" and it's been longer than that.
I think I'll wait until 2023 when the patent runs out and everybody makes them, the ones like my mom has will be obsolete. I only use that eye to look at tiny things, anyway.
Insurance paid for all but the extra thousand, it was the best thousand dollars I ever spent. The device inside my eye is my favorite device of all.
