I heard of the double vision, halos and sensitivity to bright light. But severe eye pain? :|

With all the side effects, why would folks get this procedure? In fact, what is the success rate, in terms of patients not suffering any of the side effects mentioned?

WASHINGTON (AP) -- Patients harmed by LASIK eye surgery alternated between fury and despair Friday as they told federal health officials of suffering years of eye pain, blurred or double vision -- even of people driven to suicide.

Not everyone is a good candidate for LASIK surgery, and some do suffer adverse side-effects.

"Too many Americans have been harmed by this procedure and it's about time this message was heard," said David Shell of Washington, D.C., who had LASIK in 1998 and says he has "not experienced a moment of crisp, good quality vision since."

Colin Dorrian was a college student when he was told he wasn't a good LASIK candidate, but went ahead anyway -- and his father, Gerald, described six years of eye pain and blurred vision before reading his son's suicide note to a Food and Drug Administration panel: "I can't and won't continue facing this horror."

Matt Kotsovolos actually worked for the Duke Eye Center when he had a more sophisticated LASIK procedure in 2006, and said doctors classified him as a success because he now has 20-20 vision -- something Kotsovolos charged is a deceptive industry practice. LASIK is an acronym for Laser-Assisted In Situ Keratomileusis.

"For the last two years I have suffered debilitating and unremitting eye pain," Kotsovolos said. "Patients do not want to continue to exist as helpless victims with no voice." Explainer: All about LASIK »

A decade after LASIK hit the market, the FDA is taking a new look at whether warnings about its risks are appropriate -- and pairing with eye surgeons for major study to better understand who has bad outcomes and why.

Most LASIK recipients do walk away with crisper vision, and the American Society for Cataract and Refractive Surgery reviewed studies showing about 95 percent of patients say they're satisfied with their outcome.

But not everyone's a good candidate, and an unlucky fraction do suffer life-changing side effects: poor vision even with glasses, painful dry eyes, glare or inability to see or drive at night.

How big are the risks? The FDA agrees that about 5 percent of patients are dissatisfied with LASIK. How many struggle daily with side effects? How many are less harmed but unhappy that they couldn't completely ditch their glasses? The range of effects on patients' quality of life is a big unknown -- and the reason the FDA help a public hearing Friday as part of its new move.

"Clearly there is a group who are not satisfied and do not get the kind of results they expect," said Dr. Daniel Schultz, the FDA medical device chief. The study should "help us predict who those patients might be before they have the procedure."

About 7.6 million Americans have undergone some form of laser vision correction, including the $2,000-per-eye LASIK. LASIK is quick and, if no problems occur, painless: Doctors cut a flap in the cornea -- the clear covering of the eye-- aim a laser underneath it and zap to reshape the cornea for sharper sight.

Doctors advise against LASIK for one in four people who seek the surgery, said Dr. Kerry Solomon of the Medical University of South Carolina, who led a review of LASIK's safety for the eye surgeons' group. Their pupils may be too large or corneas too thin or they may have some other condition that can increase the risk of a poor outcome.

Solomon estimates that fewer than 1 percent of patients have severe complications that leave poor vision.

Other side effects, however, are harder to pin down. Dry eye, for instance, can range from an annoyance to so severe that people suffer intense pain and need surgery to retain what little moisture their eyes form. That's the kind of question the FDA's new study is being designed to answer.

Dry eye is common even among people who never have eye surgery, and increases as people age. Solomon says that 31 percent of LASIK patients have some degree of it before the surgery and that about 5 percent worsen afterward.

But dry-eye specialist Dr. Craig Fowler of the University of North Carolina says other research suggests 48 percent of patients experience some degree of dry eye at least temporarily after LASIK. Cutting the corneal flap severs nerves responsible for stimulating tear production, and how well those nerves heal in turn determines how much dry eye lingers long-term, he said.

The old process involved cutting a cap of the cornea, the newer processes are very quick and strictly involve the laser and no cutting, which is where most of the errors occurred. All of the failed procedures these days are really caused because of poor screening.

I've considered doing it and it's really a brilliant procedure and great technology. I don't doubt that there needs to be better screening and in particular some sort of ratings system for doctors, because the doctors you go to truly need to be specialists with years of experience in the field, not just in LASIK. I went to a few doctors and the best advice I received wasn't from the LASIK specialists, but from the experienced optometrists. They have to deal with the delude of questions and I personally believe that their gray hair isn't biased. For instance there are negative effects even if the operation is 100% successful. Like with contacts your near sightedness will worsen, and compounded with worsening nearsightedness due to age, I choose to stick with contacts because LASIK was too permanent.

In my opinion the people who choose to go with LASIK do it for convenience and have used contacts and glasses for years. While I wear daily contacts, it's not really that big of a pain that I would want to risk it. I might have to spend an extra grand a decade with my contacts, but I'm guaranteed to have the choice of taking out the contacts and improving my nearsightedness and I have zero risk for a failed procedure. I know people who have had complications and those who swear by the process, but at the end of the day, the permanence of it was too permanent and the risk was still too high, no matter how qualified the LASIK surgeons I found.
