I do not have cataracts, but I am very near sited and I have worn glasses since the 4th grade. Two years ago I got pre-screened for Lasik by my ophthalmologist, but when I went to see the eye surgeon, he looked my eyes over and told me that I wasn't a great candidate. I'd maxed out my FSA in anticipation of the surgery, so I decided to try contacts for the first time since high school.
After much experimentation, what I determined worked the best for me was a slight amount of mono-vision. I wear a full power contact in my left eye, and in my right eye, which has the best vision, I wear one that is .25 power less than optimal (-4.75 vs. -5.00). With this combination I can use my phone (4.7" screen), see the car's dashboard and generally function without reading glasses. Exceptions are for small print and the dreaded dark menu in a dark restaurant.
I guess with cataracts you may not be able to experiment with contacts, but I was dead set on getting both eyes done for the best distance vision with Lasik. Now, if it was offered, I would choose the slight amount of monovision that I have with my contacts.
Edit to add: we have been unable to convince my 95 year old father, who needs cataract surgery, that there is no eyeglass prescription that will help him read the newspaper. Reading this thread has helped me understand it better, but still not sure how we can explain it to him.
