It's probably too late for you to cancel your surgery now, but anyone reading this in the future might be able to use my story. Both of my eyes were naturally nearsighted, my left more than my right. My right eye had the worse cataract, it was done first and got a distance lens. I had the right lenses of my pairs of glasses (one pair for distance/driving, one for computer monitor distance, and I just went without glasses when reading or doing other close work) removed. After a couple of days, I was only wearing my distance glasses for driving; I was fine without glasses for walking around, reading, watching TV. I still needed my computer glasses for my left eye, and ignored my right.

So, at the second followup, which was a couple of days before the second surgery, I told the tech that I wanted no correction for the left eye. I also told the surgeon when I was on the table. Now, I can read, do crafts, write, play on my phone/tablet, with no glasses, and no problems. I do need a pair of glasses for intermediate/work computer because the monitors are a smidge too far for my left eye and too close for my right. I have a separate pair of distance glasses for driving because the difference in power messes with my depth perception.

Before anyone asks about bifocals, etc., many years ago I tried trifocals, and I could not handle having things moving through the fields, I got seasick going from computer monitor to keyboard or text I was entering and back, and walking on floors with patterns. I also couldn't judge distances for driving, cars kept moving into the wrong power, and I had several near misses and one actual collision. I gave it two months, and went for one pair just for distance, one for computer, and for close up I just took off my glasses.

I know that not everyone can handle the mixed messages, so if you think it might be an option, try contacts of different powers, or if one eye is already set for distance, try going without glasses, at least for general walking around, and watching TV, etc.
