Referring to cataract procedure. had it done a year ago, had been wearing glasses since age 45 (now 73) and was up to trifocals. When the Dr asked "what type' vision I wanted , I stated sharp vision distant instead of up close for reading. was it worth it ! Absolutely ! u[ close reading only need 1.5x reading glasses other then that vision is sharp, clear. I can see and read up close, like computer screen with out glasses but they just make it a little easier. anything else greater then arm length or farther is great !
