My Mother-in Law had cataract surgery in both eyes (they generally do one at a time). By the time she was done, she could see a pin on the carpeted floor from 30 feet away that I couldn't see from five feet away! I've worn glasses since I was eight (I'm 65 now) so it wouldn't be a big deal for me to continue wearing them for the opportunity to continue to do up close work or read without glasses (I do almost all my model building and reading without my glasses-- in fact, I'm typing this without them now. But it's an individual choice, it seems to me the mid range would be fine if you don't do a lot of close work now. Before I retired from the Army, the docs wanted to do laser surgery to give me 20/15 vision. But they make you wear special contacts for a day to see how you like the "new" vision. I went in at 0700 in the morning, was fitted with the lenses, and initially loved walking out of the hospital without my glasses-- for the first time in my life, I could see objects as far away as a mile in crystal clarity. Until I got behind the wheel of my car-- the instruments and dashboard were seemed a bit "fuzzy". When I got to my office, my computer screen was also "fuzzy", as were all the papers, my desk, and everything within arms reach. After wearing the contacts all day, I asked the doc when I went back to the hospital that night about it, and she told me if the do surgery to change your vision for distance, it will always affect your close in vision. So I decided then I'd rather be able to see close-in than farther away. But that's just me-- you may feel differently.
