What is the maximum nearsightedness degree one can have to qualify for LASIK surgery?
Q. I heard that Tiger Woods got successful LASIK surgery and he was -11 nearsightedness. My eyes are pretty bad and I need some info on this. Thanks.
A. It depends on each individual, most importantly the thickness of your cornea. LASIK works by ablating, or destroying, some of the inner layer of your cornea. By doing so, it effectively flattens the cornea and corrects your vision. The higher the prescription the more tissue needs to be ablated. So if you have a really high prescription and a thin cornea, LASIK would not be an option. There are a few other procedures that may be an option if LASIK isn't. Go see your eye doctor and get more information.
Will LASIK surgery prevent you from riding a roller coaster?
Q. I heard that if you have LASIK surgery, you can no longer ride a rollercoaster, pilot an airplane, or even ride a car with the top down. The so-called reason is that the flap in your eye created by the laser might open up again or come loose in the event of high-G forces or gusts of wind. Is this really true? I love roller coasters but am thinking about getting LASIK myself and would love to know the true answer to this myth.
A. Good heavens. Someone is apparently trying to scare you away from Lasik, is completely uninformed, or both.
I work for a nonprofit Lasik patient advocacy. We don't provide Lasik. We provide Lasik information and certify Lasik doctors' patients' results.
The first step in Lasik laser vision correction is to create a thin flap of corneal tissue. The flap is moved aside, laser energy is applied, and then the flap is repositioned over the treatment area. By applying the laser energy to the inner portion of the cornea the eye is "fooled" into not realizing it has had surgery. This mutes the wound response and contributes to Lasik's rapid vision recovery and general lack of pain.

Within minutes of flap repositioning the flap has adhered to the underlying cornea due to the natural suction created by the cornea absorbing oxygen into the eye. This is why you can blink immediately after Lasik and not dislodge the flap.
Within a few days a seal around the edge of the flap begins to form. This seal eventually acts like the lid on a Tupperware bowl to strongly adhere the flap to the underlying corneal surface. For a detailed explanation of the Lasik flap healing process visit:

The United States military has approved Lasik for fighter pilots, who experience significantly greater G-forces than you would experience on a roller coaster. Special service branches of the military, such as Navy SEALS are able to have Lasik. This is a group in extreme environments. At a recent US Food and Drug Administration hearing David J. Tanzer, M.D., Commander, Medical Corps, US Navy, and a Lasik surgeon extolled the virtues of Lasik and similar refractive surgery for US troops.

There are about 1 million Lasik surgeries throughout the world each year. If the Lasik flap was going to flap in the wind when riding in a convertible with the top down, don't you think you would have heard about it on the news? I suspect that if Tiger Woods� Lasik flap dislodged � or the flap of other prominent sports personalities, movie stars, police, fire fighters, and others who have had successful Lasik - you would hear about it.
Although the Lasik flap does heal, the cornea is always different after Lasik. Once you have had Lasik, you have always had Lasik. Significant trauma to the eye can dislodge the Lasik flap. Fortunately this is relatively rare and if the flap is intact it can commonly be repositioned and will heal.
If you are involved in activities and sports where trauma to the face and eyes is very likely, such as a professional fighter, then Lasik may not be appropriate because of the high probability that you will suffer blows to the eye. Even if a problem is unlikely, it seems prudent to consider Lasik alternatives such as PRK, LASEK, and Epi-Lasik. These techniques, commonly known as surface ablation, do not require the Lasik flap. The patient will have a much longer vision recovery and more discomfort, but laser vision correction without a flap is available.

Did anyone else ever hear that Tiger Woods had eye surgery prior to his golf career that enhanced his eyes?
Q. When I say enhanced, I am talking about better then 20/20 vision that gives him an edge on his game. Was this just a rumor or does anyone have documentation to back this claim up.
A. tiger woods had lasik eye surgery. he used to have a stgmatizm or something and wore contact lenses. its not a radical surgery or anything that would improve his edge over the game. he was tired of wearing contacts and glasses. he even did a commercial for the company like 5 years ago.
What do you feel is the problem with Tiger Woods game?
Q. If he misses a couple of makable putts, doesn't he seem to
get too flustered?
get too flustered?
A. Of course if Tiger misses the short putts it's frustrating. Maybe he doesn't practice the short putts enough. Usually the probability of a pro making a short putt within 3 feet is really good.
I've played on lightning fast greens so fast you just touch the ball and it travels 20 feet. Most public courses have medium-slow speed greens. The putting on fast greens is very difficult, if you hit it strong the ball can zip way past the hole, if you hit it lightly it's more susceptible to the variations of the grass on the green and it can twist your ball into another direction, or catch the rim of the cup and spit it out, so those short putts are very tricky.
I think a lot of very strong players distance wise have trouble getting the feel of the greens and the right ball speed. Tiger had Lasik eye surgery years ago and maybe his vision isn't 100% although undetectably so.
Tiger also is bulkier up top, whether he works out his upper body more, or his swimming and scuba diving have increased his shoulder strength and muscles, it might not be good for golf. Golf relies on long lean muscles. Look at Rory McIlroy today, a scrawny 23 year old took the title by 8 strokes. Tiger's physique has changed a lot since he was 23. He may be fit and trim, but not correctly for golf. He needs Pilates more than weights.
