Unless things have changed, be sure you keep the little note they give you at the end that tells you your measurements. Supposedly if you end up needing another round later in life, it may be necessary to have those measurements. They apparently need to know exactly how much corneal tissue was there originally to know how much more they can remove.

And be sure you do your annual check-ups. The place where I had mine done guaranteed any follow-up procedures would be free for life, but only if I could show I'd been doing the annual check-ups.

That's about all I can remember. After the procedure, you go home and take a nap. For me, I woke up the next morning and could see clearly.
