Oh, I wasn't disputing your statements. I realize that RK has a longer history than LASIK. I looked into RK back in 83, when I wanted to fly helicopters. I had the brains, but my eyes were bad. Army sent me to a Navy flight surgeon who gave me the info on RK (at that time). Too pricey at $20,000 and nobody (even the Navy) would allow it.
I agree about "long term" viability, but even RK doesn't meet the long term test. 20 years is a lot, but it ain't nothing in a lifetime. The success rates of LASIK over RK are significantly higher, with lower incidences of side effects common to RK incisions (infections, scarring, flare and starburst, etc).
For the general soldier and sailor, I believe LASIK (or a refined form of it) will become THE standard, if not the ISSUE means of correcting vision problems.
