I had undergone a cataract surgery in San Antonio about a year ago.

I had it on the right eye first and waited for 2 weeks for the left eye. I had both my eyes focussed for distance vision. If you prefer one eye for reading there are chances of getting squint eye or even double vision. Talk to your eye specialist and seek an expert solution.
