I also remember
The Russians perfected what was then call Radial Keratotomy after a school kid wearing glasses was punched in the face, sending shards into eyes. After patching the kids eyes up,(and a bit of healing), the kid noticed his nearsightedness was almost gone.
Within 3 years they perfected it to the point of those 6 bay radial surgeries, the doctor was a bit a bit of rock star , considered "The Guy" to have this done by.
Now we into PRK and radar mapped PRK, amazing what 30 years can do for a procedure. The best quote I've ever heard regarding this type of surgery,(and it is surgery!) is "I would never have my eyes worked on for $400 each, I would however, consider it at $800 each".
You get what you pay for, as much as I need it done now( -7 index, plus now I need reading glasses on top of my contacts, ultimate irony), the idea of these clinics gives me the heebie jeebies .
