(Not that this is going to change anyone's mind about this decision)
My wife had RK surgery (which is an incisional, a.k.a. scalpel, alternative to the laser surgery) some ten years ago. Since she worked for the ophthalmic surgeon at the time, it was FREE.

(Granted, had it cost us, she wouldn't have had it done; we are poor folk!). However, her vision is still perfect to this day. (Oh, and she's been an insulin-dependant diabetic since she was a year old, for those of you with similar concerns)
At the time she had her RK surgery done, LASIK wasn't even approved in the U.S. yet (not until 1999). However, radial incisional surgery for vision correction has been around in various forms since the late
1800s! Although approval in this country is always decades behind anywhere else, vision correction surgery is well past the period of "let's wait and see what happens." We trust much newer technologies to heart surgeries and all manner of other important procedures.
If any of you are holding back on LASIK/LASEK because of possible long-term ramifications, there are other
older options that will give you the same or similar advantages, and are old enough to have had decades of history behind them.
