Oops. I see you haven't had it done yet.... I thought you had, so here's one more very important piece of advice.
DO NOT GET THEM CORRECTED TO 20/20!!!!!!!
I cannot emphasize this enough.
Have them undercorrected so you CAN read. 20/40, I think is the number, I forget exactly.
This also helps greatly on a pool table. Think about it...How often do you really need to see at great distances? Rarely in today's world. 95% of what you look at is within 10 feet or so, even if you don't play pool.
My ophthalmologist and I had long discussions about this. He was totally against my undercorrection, but after 5 years of contacts (his requirement of me, due to my age, before he'd cut me), he finally conceded to my wishes. Funny thing is, at my last appointment, he was telling me how the surgery is changing to having undercorrection as the norm, as if it was his idea in the first place.
Good luck,
Jeff Livingston
I wish I had did this. I don't like having to use reading glasses.
