As you may know, cataract surgery is one of the most, if not THE most, common surgical procedures done in the US. Much has been improved and streamlined with cataract surgery and implants over the years, so that it has almost become assembly line surgery.
I'd suggest that you follow pre and post operative instructions as well as possible, and should anything out of the expected normal during the post op period occur, which is quite unlikely to happen, you notify your ophthalmologist's office immediately.
Choosing between the single vision lens implant and multi-focal lens implant might be your most difficult decision to make. It might be worth the while to have a private discussion with your eye care provider, not necessarily the cataract surgeon, what they advise and what, if any, good experiences, or complaints they have heard over the years from patients who have undergone the procedure.
Best of luck to you, and I'll be rooting for you as well.
