My story - cataract in right eye, developed last summer, somewhat corrected by glasses, but barely. Trouble seeing at night. Very blurry close up until about 5-6 inches. And it's getting worse, so I'm ready for the surgery. Also a high degree of astigmatism in the right eye (but not the left), so I'm getting the Toric IOL.
My left eye is -2.5. I was originally thinking of going for a 0 in the right eye - wouldn't that be nice, to be able to see distances without my glasses? But I was told the difference in diopters is too great, and I'd have to wear a contact lens in my left eye (at least until that one needs the surgery as well, which could be anywhere from 6 months to 10 years). And that sounds horrible.
Then I realized that what I REALLY want is what I've been used to my whole life - perfect near vision. I like to read (a lot!), and I'm also a (semi-retired) software developer, so I spend lots of time in front of the computer, on the phone, etc. Until I was about 40, I had perfect near vision to about 2-3 feet - so I never used my glasses for either reading or the computer. In a perfect world, I'd be able to regain that ability after the surgery.
My left eye (which is dominant) still sees perfectly well at about 12 inches, so I can "sort of" read, but it's not very pleasant - even with the reading glasses I got a few months ago to correct the right eye.
I was originally told my choices were "distance, intermediate, or near" - meaning 0, -1 or -2. I was leaning towards getting -2, because even with a -1, there would still be a 1.5 diopter difference between left and right, and I understand that's pushing the limits - although apparently my all-around vision will be better by getting rid of the astigmatism. I guess the doctor doesn't want to confuse people, but after a little research, I asked about numbers in between those, and she said, "Sure, we also offer a -1.6."
So what I'm wondering about is, what would be the difference between a -2 and a -1.6 toric IOL in my right eye, with the left eye at -2.5? Would I be able to both read at "normal" book length (12 inches or so), and read the computer screen (24-36 inches) without glasses? That would be my dream... Or, if I go for the -2, would I still need computer glasses (or progressives), as I've been using the last 15 years? (And which I hate...). Above all, I REALLY don't want to have to wear any glasses when I'm reading. My entire life, I've enjoyed taking off my glasses and getting in bed with a book...
As they said in Fast Times at Ridgemont High, "I'm soooo confused!" Any thoughts or ideas are appreciated! Surgery is scheduled for April 17, so I have about 5 days to figure this out!
