If you read through the archives of this forum, you'll see that sometimes glasses help in cases of multifocal "disasters," and sometimes they don't. As a former cataract patient, my best advice would be to have your surgery done by an experienced cataract/refractive surgeon. Get aspheric monofocal lenses, which can be set for best vision at distance, intermediate, near, monovision, or modified monovision. (Discuss these options beforehand with your surgeon to determine which would be best for you.) If you have astigmatism, see if it can be corrected at the time of surgery. I think that it's extremely likely that you will be very pleased with your results.
Please read the answer to your first questions and see if that calms your nerves.
