Alan:
I had it done in 1998 by the doctor Leigh Anne and Shelly Anderson recommended. I think he's still in jail for Medicare fraud but that's another long winded story. He lost his medical license.
My prescription was beyond a -6 (minus 6). In terms of vision, 20:400 means you see in 20 feet what most people see in 400 feet. I had no vision beyond the end of my nose so the 20:20 whatever you call it didn't apply.
Lasik in the late '90's compared to today's technology is like comparing standard TV to HD. The results today are incredible, but you need to find a good doc, not a chop shop kicking out 40 an hour. They use a digitized computer scan of the eye kinda like a relief map, imput the information into the Lasik compter and the lazer cuts your eye to reshape the cornia to obtain perfect vision.
As you know I almost lost my left eye in the pits while warming up our car in Tucson in 2007. Even though my eye was impacted by a rock that exploded my sunglasses it did not knock the cornial flap loose. The cornia is cut and folded open during Lasik and never fully reattaches itself. It was explained to me that it sticks to the eye once back in place like velcro, but never grows back together. By all accounts it should have been blown away but it wasn't, so that's good. They will tell you that immediately after surgery and during the recovery period you need to be careful about rubbing your eyes because you could rip the cornial flap off.
12 years later at 54.5 years of age (aaugh!) I heve excellent vision but I'm about 2 years into reading glasses for only the smallest print in low light or if I'm trying to look at something very small. Normal reading in normal light I don't need reading glasses.
I considered mono vision but decided against it for two reasons. 1). The thought of having one eye out of focus for distance and the other out of focus for reading gave me a headache (my mom did it and later had it undone when she had catarac surgery). 2). Even with mono vision you are likely to still need reading glasses eventually anyway so why go around looking like Marty Feldman.
Call me if you want any more info. They had to do two surguries on me due to the extent of my myopia. When all was said and done the biggest thing for me was being able to see the faucet handles in the shower and not having my glasses fog up when I drove my TA/FC (and when snow skiing). 12 years later I'm still reaching for my nose to push my glasses up. Duh.
Also, the little pill they give you before the surgery really makes you relax. So much so, you feel like you wouldn't care if someone walked up and scratched your new car.
