Good luck on the one-day prep and first cataract surgery tomorrow, DR Ron Pulliam.
I forget the details now, but I had to start eye drops a week or more before, and those and other drops continued for a few weeks after. That's the only pain in the ASS about the thing. The drops regime seems to vary among various doctors and patients.
Other than that, as the anesthesiologist told me while I was lying there waiting for the surgery, this is literally the easiest surgery you can have, just relax and enjoy. You walk in, my place had us lie down on the cart (that'll be wheeled in to the surgical room, you don't even have to move from it), fully dressed (with a smile, of course), and you're given coffee and a cookie afterward and wheeled out to your ride. Then just do nothing (I slept a lot) the rest of the day, and Bob's your uncle. Actually, I don't think I got an Uncle Bob, but everything else worked out fine.
