The U.S. Navy's Doctrine of Laser Eye Surgery
The New York Times reports that laser eye surgery — now performed on nearly a third of every new class of midshipmen — is transforming Naval careers. Navy doctors are performing these operations with "assembly-line efficiency," allowing older pilots to continue flying, and those who might otherwise have been disqualified to pursue flight school. The number of procedures has reportedly climbed from 50 to 349 over the past five years. The Navy uses a different procedure than that used on civilians — grinding the cornea rather than cutting a flap — out of fears that the flap could come loose in supersonic combat.
I've had glasses since I was 11 months old, and as much as I'd like to get rid of them, getting flaps cut or 'ground down' just dont sound very appealing to me.
Your hair look like poop, Bob! - Wanker.
Their explanation in both cases was the same: we really don't know the long-term effects of PRK/LASIK/LASEK. It could have side effects (triggering glaucoma, etc) that would render you near blind in 30 years. Is it really worth that risk?
So I'm sticking with glasses. For one thing, I'm over 40 and while I'm still nearsighted, normal age-related presbyopia is setting in. I can deal with it by simply removing my glasses to look at things that are up close. If I had LASIK, I'd need to carry reading glasses with me all the time, so there's not much of a win.
I'm not qualified to comment on the skills of Navy docs in general, but if I were going to get laser eye surgery, I'd feel pretty comfortable knowing that the doc who's going to be doing it has done literally thousands of that same procedure before, and has turned out results good enough for their patients to qualify as fighter pilots.
Just my $0.02
Next up was a device that measured my perscription. I had to stare at
a little picture while it zoomed in and out of focus. Apparently this
determines my exact perscription, none of that "Is this better, or that"
lens swapping. I wonder why eye doctors don't use this all the time.
Well, there's a number of reasons... the machines are expensive, and they're even more expensive for really accurate models. They aren't perfect, and sometimes get it wrong (but that's usually pretty obvious when the lenses you get just don't work for you, and a second check on a different machine should catch this).
But the #1 reason? If you check somebody's eyes in 30 seconds with a machine, instead of spending 10 minutes doing it by hand, many people don't think you're doing it properly, or don't think they're getting "their money's worth". It's utterly stupid, but so are the majority of the people who go to an optician - remember, it's the same people that TV is made for.
Due to thin cornea's, I opted to have PRK done on my earlier this year (rather than LASIK). I have no plans on doing supersonic flight thought, and am VERY VERY happy with the results.
The quick pro/con list of PRK vs. LASIK:
pro PRK:
no cutting of the cornea
con PRK:
can be more painful
longer healing time
The results of both procedures are exactly the same.
