On the other side of the knife...
OK, so it's probably a laser instead of a knife. Still, if you've been riding with prescription glasses or sunglasses, start thinking about how you'll protect your eyes from clouds of gnats, or other things in the air, while you're riding. I ended up getting two more pairs of glasses, one clear (with 1.5 readers) and one sunglasses (with 2.0 readers; hey, it's what was on sale).
The week after my second eye was done, I stopped by Wally-World and bought three sets of reading glasses to figure out what I needed for reading and for computer work.
All five glasses together cost me less than just my last prescription frame. Lenses were much, much more.
FWIW, I went with the straight single-focus lenses, and my astigmatism disappeared. My wife got the conic lenses, and she's still trying to get glasses that'll fix the residuals in her prescription. YMMV.
