My mother has. She has two cousins (brothers), who are both opthamologists (and who's father started their practice as an opthamologist himself). Matt, one of her cousins, recommended a doctor in Memphis, while Matt did the pre-op and post-op (they practice in Tupelo, and that's a lot closer than Memphis). Mom had it done, for about $2500 (I'm relying on memory here, I think that was the approx. price) on just her left eye. I do know that the doctor does a lot of LASIK operations a year, how many I don't quite remember. 500 maybe? Afterwards, both Tom and Matt said that the doctor had done an absolutely flawless operation. I know my mother was not the perfect candidate for LASIK because she had astigmatism, yet she had a perfect operation. The only tricky part was that she had to keep a special contact on her eye for a few days afterwards and keep it lubricated, so that the corneal flap wouldn't move while it was healing.
Because of her astigmatism, Mom (who was 52 when she had LASIK performed, she's 53 now) wore gas permeable contacts until several years ago when she developed an infection in her eye. She couldn't wear her left contact without pain. In fact, the last time she flew with both contacts in (required by her medical), it caused her severe pain that lasted several hours after the flight). But I know she's extremely pleased with the operation. She would've had it done to both eyes if she'd had the extra money, but two kids in college can find many ways to spend $2,500.
If you'd like, I can e-mail Matt's current office (he has since amicably split from his brother and opened a new, larger office) name and number. The doctor in Memphis who performed the operation is the best in Memphis, Matt said, and if you'd be willing to come this far to have the operation done, it would be worth your while.
