The U.S. Navy's Doctrine of Laser Eye Surgery 547
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.

You would think that you would take care to make sure you get a good surgeon. I did a lot of research on the internet, found a surgeon with an eyeball tracking laser and made sure he was doing the right tests and executing due dilligence prior to the surgery. I also dropped 2 grand an eyeball to have it done. Now the thing is, when you're doing something like this, why would anyone even consider "Bob's Discount Lasik -- Buy one Eye, Get one Free!" Or going to Thailand to have lasik done? Sure you might shop around on a car or a sofa, but when your body's involved the first point of consideration should NOT be the price of the procedure.
Anyway I did the research and decided the risk was worth it and now have perfect vision in one eye and better than perfect vision in the other. I'd do it again in a heartbeat. It was hardly uncomfortable at all, too -- I just had to take tylenol for a slight headache.

Like lots of things, I think it's a risk/reward question. In my case, I wear glasses and will continue to wear glasses, but my vision isn't that bad so the reward I'd get from eye surgery isn't all that great. The glasses sharpen my vision and make it easier for me to read road signs, but I can actually get along just find without them.
My wife, on the other hand, was blind as a bat without her glasses, to the point that she had to carefully place her glasses in the same place next to the bed each evening, because she had to find them by touch in the morning. She could not see them. She got Lasik about three years ago, and it has significantly improved her life. Before the surgery, for example, she didn't dare participate in any sort of water sports because losing her contacts or glasses would leave her completely blind. Now she SCUBA dives and I expect to get her up on water skis this summer. Even more important is the sense of freedom she has, being able to see without assistance. After the surgery, her sight was 20/20, but has gradually declined to where she is contemplating getting glasses again to sharpen her vision a bit. She could have the surgery re-done (for free, even, since a followup was included in the original price) instead of getting glasses, but it's no longer worth the pain or the risk.
I know others with similar stories, and I can definitely see how someone who'd like to fly military jets would perceive the risk/reward tradeoff as a good deal. Heck, I'd get the surgery if it meant someone would let me fly an F-14.

Nearly a third of every 1,000-member Naval Academy class now undergoes the procedure, part of a booming trend among military personnel with poor vision. Unlike in the civilian world, where eye surgery is still largely done for convenience or vanity, the procedure's popularity in the armed forces is transforming career choices and daily life in subtle but far-reaching ways.
Aging fighter pilots can now remain in the cockpit longer, reducing annual recruiting needs. And recruits whose bad vision once would have disqualified them from the special forces are now eligible, making the competition for these coveted slots even tougher.
But the surgery is also causing the military some unexpected difficulties. By shrinking the pool of people who used to be routinely available for jobs that do not require perfect eyesight, it has made it harder to fill some of those assignments with top-notch personnel, officers say.
When Ensign Michael Shaughnessy had the surgery in his junior year at the Naval Academy, his new 20-20 vision qualified him for flight school. And that is where he decided to go after graduating last month ranked in the top 10 percent of his class, rather than pursuing a career as a submarine officer.
"The cramped environment in submarines is something that turned me off," Ensign Shaughnessy, 22, said.
For generations, Academy graduates with high grades and bad eyes were funneled into the submarine service. But in the five years since the Naval Academy began offering free eye surgery to all midshipmen, it has missed its annual quota for supplying the Navy with submarine officers every year.
Officers involved say the failure to meet the quota is due to many factors, including the perception that submarines no longer play as vital a national security role as they once did. But the availability of eye surgery to any midshipman who wants it is also routinely cited.
"Some of the guys with glasses who would have gone to submarines or become navigators are getting the chance to do something they'd rather do, and the communities that are losing the people are not as happy about it as the aviation community, which is gaining better candidates," said Cmdr. Joseph Pasternak, the ophthalmologist who oversees the program at the National Naval Medical Center in Bethesda.
In the Naval Academy's class of 2006, 349 of the 993 midshipmen had the surgery, up from 50 five years ago, according to Naval Academy records. Fewer than 30 percent of the academy students whose eyes qualify for the surgery choose not to get it, and the number of holdouts is dropping every year, Commander Pasternak said.
Last week, a little after 10:40 a.m., Colin Carroll, a 21-year-old midshipman from Olney, Md., put anesthetic drops in his eyes and lay down under the laser as Capt. Kerry Hunt, a Navy doctor, and two assistants prepared to begin. "We're locking the laser on now," Captain Hunt told him.
Midshipman Carroll had originally hoped to enter flight school but discovered not only that his eyes were not good enough, but also that he was prone to kidney stones, ruling him out of aviation entirely. He said he was "resigned" to entering the Marine Corps or becoming an officer on a surface ship, neither an assignment requiring perfect vision.
But he decided to get the surgery anyway.
By 10:49, both eyes were done, though extremely bloodshot, and Mr. Carroll walked out wearing sunglasses, declaring he could already see better.

Next up they took two pictures of each eye. It was a weird device, it

Then I got to speak with the doctor. She did a few more measurements,

However....I am an exceptional canidate for PRK, which is basicly LASIK,
but with no flap, they just burn off the extra portions of the cornea.
The recovery time is a bit more involved, and would likely be unable to do
much of anything for a couple of days. I'd have to wear contacts as

4 hours post op:
Well, I did it, and I'm not blind.
It went very smoothly. Arrived, filled out a couple (more) consent forms, one last cornea mapping, and had a last minute chat with the doc. Got a perscription for some vicoden, and got my final post-op instructions. Paid the nice lady, and she gave me some Advil and a valium. Back to the waiting room for 10 minutes.
The proceedure itself I can't really describe, as most of the time I was staring at a bright light 6" from my face. But, they gave me a stylish hair net, and ploped me in a dentist like chair. Leaned me back, and it slid me under the light/laser/camera.
They gave me a half dozen eye drops in each eye and let me sit for a few minutes. I know one of them was an anastetic, hence the wait. They put a plastic shield over my left eye, and taped it in place. Then they tapped my eyelashs/eyelids open on the right eye. They put in the thingy that holds my eye open, which wasn't as uncomfortable as I thought it would be. Few more drops, and then they (according to C) put a little white disk over my cornea.

The "flap" is a thin, transparent layer over the cornea which is peeled back to allow the laser to shape the cornea, then it is placed back over the cornea and it heals. Older surgeries used to discard the flap entirely, but a crescent heals faster and with less discomfort.
In my case the flap was discarded, it grew back with no problem. There was discomfort for the first week or so.
I was awake during the entire process. They gave me a mild sedative but I don't really think it was necessary - there was nothing particularly exciting about it. The eye was anesthetized, of course, and this was tested before the procedure began. I was using the eye up to and during the surgery, at which point it was bandaged over.
The actual laser part involved looking at a particular spot while the doc counted up some numbers like he was zeroing in on some chosen value. That's all there was: just look at some spot for about a minuts and it's done. No laser (visibly), no sound, no feeling, no buzzing or cutting or anything like that.
The anesthesia wears off a couple of hours later, and the eye hurts like it has a bad foreign object in it, but it the pain was periodic and not excruciating. It didn't prevent me from working on the computer.
There's nothing particularly exciting or scary about the procedure, and when it's all over you get to see clearly without glasses.

Lasik, cuts a flap into the stroma, this is not the same flap that is removed for PRK as some folks have been characterizing. Alarmingly this flap never full seems to heal. It has been lifted YEARS after the original surgery. Lasik permanently weakens the cornea.
PRK is essentially moving or removing the epithelium. A thin surface layer that will grow back, not the deeper flap cut in the above. Variant (LASEK or epi-Lasik) attempt to preseve the epithelial layer and use it as a sort of bandage during healing. This helps speed the healing and lower pain, but it is still not as good as traditional Lasik.
Bottom Line:
PRK and variants, better/slower/more painful. Laskik has more issues/complications, but is more comfortable/faster.

In PRK, the outer surface of the cornea is ablated by the laser (on an lower power) and then reshaped at a higher power. A protective contact lens is applied to patient and remains on for about 5 days, then is removed by the doctor. The patient applies drops to the eye several times a day for about a month while the outer cornea heals.
The benefits of PRK are the lack of any "flap" problems (incorrect cut, complete cut [ouch], misalignment, dislodgment, halo effects, etc...) and ability to correct some visioin situations not correctable via LASIK.

A CVBG (carrier battle group) is mobile. The fact that the carrier itself carries multiple platforms which each excell at different types of missions helps.
Also, in a CVBG you also have (usually) two guided missile cruisers, two to three guided missile destroyers, a frigate or two, two attack submarines, and a supply ship (refueling/resupply of ammo). With this combined platform, you have the following:

Also, the doctors who treat the President are from the Navy, and Bethesda Naval and Walter Reed are known to be very good medical centers. So I think your post is basically quoting people who have some slant against the military.

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.

My friend is a Army dentist in Germany. The army picked up his 3 years of dental school, which cost around $200,000. He owes them 3 years now. He gets paid less than the average dentist, but he's stationed in Germany and since he left he's travled to the Olympics and the World Cup, not to mention all around Europe.
Also, the Army eye surgery isn't LASIK. It's PRK, which is a different procedure. They don't cut a flap in your eye for this one. My brother, a LT in the army, had it done. He had to use eye drops to treat dry eyes about 6 months.

Your point about the med school funding -- I'm considering med school, so I know whereof you speak -- is well taken.
I did have a friend in the Navy, though, who underwent a nightmarish wisdom tooth extraction. The Navy dentist gave him conscious sedation (a narcotic) instead of a general anesthetic, and then proceeded to perform an extraction that would have given any Civil War surgeon pause. My friend described the fear very effectively. Said he never slept on his back after that, because it reminded him

They must have, if your opinion was ever valid in the first place. I was an operating room tech (Surgeon: "Scalpel." Me: Passes scalpel) at Naval Hospital San Diego in the mid '90s, and the surgery they were doing was absolutely first class. We had lots of famous visitors - a friend of mine got to scrub in on a chest case with Dr. DeBakey [wikipedia.org] - and we performed a lot of routine operations that you're only now seeing in the civilian world.
I won't say that there aren't any bad doctors in the military, but there are plenty of brilliant ones to bring up the average. I wouldn't have thought twice about getting medical care for me or my family from the Navy.

The commonly held belief back then was these docs (and dentists... don't get me going on this one...) were only in the military because they couldn't hack private practice.
More like because they couldn't afford medical school another way.
My experience with military docs is that they're reasonably good physicians, but that the health care system in the military lacks continuity, and that causes problems. Also, because most of the doctors leave the military after they complete their obligation, the active duty doctors all tend to be young and somewhat inexperienced. The best thing to do, if you can, is to get one of the doctors who is a reservist.
My anecdote: The Army doctors at Fort Hood nearly killed my younger sister because she had condition (pyloric stenosis [wikipedia.org]) that is rare in girls, so each doctor wanted to exhaust all other possibilities first, and didn't really trust that the other doctors had done their job. In desperation because my baby sister was dying of dehydration and malnutrition, my parents eventually took her to a nearby civilian hospital, where they operated and corrected the problem within a few hours. To the Army's credit, they admitted their error and the correctness of my parents' actions, and covered the civilian medical bills.
In contrast, my parents now get all of their medical care through the nearby Air Force base hospital, which is generally staffed by a rotating group of reserve physicians who seem to be uniformly excellent doctors. The docs recognize the need for continuity of care and make heavy use of referral to local civilian docs for any condition that requires the sort of continuity they can't provide. They also try to arrange so that each patient sees the same doctor for routine physicals, etc.

I worked at Walter Reed Army Medical for years on a software project for the chief of neurosurgery. I came to find that he was considered one of the best neurosurgeons in the world. Why? Because the military sees a lot of spinal injuries of course. Walter Reed is the same place that works on the President of the US, congressman, etc. Is the president going to get a hack for a doctor?

But to respond to your worries, they do give you drugs to calm you down if you want them (I would recommend it) although they do not put you under you have to stare at a light while the laser goes to work on your eye. The actual worst part is when they cut the flap - they had to wait a few minutes while my eyes dialated, so for a little while had a flap cut in my eye and was just sitting in a chair in a dark room. But altogether it took only half an hour and it was time extremely well spent.
