Do you dare take the risk to jumps from aircraft using a parachute? Do you want to remove glasses and to correct your vision through LASIK surgery or laser-Assisted in situ keratomileusis.
Millions of people of North America had do the procedure and satisfied with the results. However, at this time Food and Drug Administration (FDA) want the warning on the information material to patients about the effect of complications.
But The problem is just like as the parachute that failed to open, it can also occur a harmful surgery complications.
permanently LASIK surgery change the curve of the cornea shape , the transparent membrane at the front of the eyeball and transparancy. A laser device is used to make the incision flap (layer) on the eye cornea and leaving some still stick to the flap at the end of the cornea.
Then the laser computer vaporizing the tissue that under the flap, then the flap returned again to the original positition. The satisfied results are very interesting, who does not like the vision is better without the contact lens and eye-glass.
However there are many posts about the benefits of LASIK surgery will be more prudent for the prospective patients to know the potential risk.
After LASIK surgery, the flap in the cornea that was sliced and then returned to the original position, there possibility can be shifted, causing the occurrence of a problem.
And possibility infection will also cause at any time, anywhere at the sliced is made on the body. This may require an intensive treatment and may lead temporary vision loss or even permanent blindness.
And it is important to remember that laser machine tools may not always do what they should do.
Some patients are suffer side effects that ruinned the quality of vision even though have improved their vision sharpness. For example, although the vision test with the eye chart (a test to measure off the vision sharpness) shows good results, some patients still can not see in light conditions with low contrast, such as when driving at night or in foggy conditions.
There is study, 41 percent of patients have good vision in the daytime, but some have lost their vision at night.
In another study, people who have a short-distance vision (short-sighted) who undergo laser surgery, 80 percent can not see the traffic sign on 15 cars distance, and 40 percent can not see the traffic sign on 4 cars distance.
This is worrying, as a drunk driver. But with millions of people who undergo LASIK surgery, it should be asked how much the trip will be done at night.
Moreover, laser surgery can not stop the aging, the vision in the night of course have been decreasing. This causes double-whammy.
Some patient post-surgery has suffered a decrease in quality of vision problems such as double vision, or about there is a garish light circles on the vision.
May also occur the action of unprofessional treatment or excessive in the patient, resulting a vision in less than 20/20.
In one study, 36 percent of those who perform surgery on both eyes still need glasses. The another report states that 2 percent from 10 percent of people still need glasses after LASIK surgery.
The other suffered dry eye syndrome. In this case, the eye is not able to produce enough tears to keep eyes stay moist. This does not only cause restlessness, but sometimes also a blur, and this may become permanent.
And what all this means? This column does not currently intend frighten people who want to perform LASIK surgery. This is the wise expression for patients to follow the advice of the Roman era have been proven effective in a long time (time-tested), which is "examine before buying a".
Only, you must be a patient who fully understand the information before agreeing LASIK surgery. And someone who says to you that there will be no cereal bowl-pplications, is a liar or stupid people.
Decision even more difficult when LASIK surgery is done only for convenience not because it needs, given that the majority of cases end with good results.
The problem is, you will not know when there will be a rare complication. It is a grisly sight when the loss occurred only because you want to remove the glasses.
So you should always be prepared to accept the risks when considering to perform LASIK surgery. Do not forget that on rare occasion, even a perfect parachute can fails to open.

Lasik Surgery Complications
Who have lived most of their lives under the mercy of eyesight problems such as nearsightedness, farsightedness, or astigmatism, LASIK is alluring. The benefits of having the lasik procedure are obvious and well documented. The promise of LASIK is indeed very inviting, but before you decide to have it, you must be aware of the LASIK risks so that you won’t regret your decision.
Though rare, there are still LASIK surgery patients that complain about post surgical problems. However, if you have an experienced surgeon by your side, the rate of surgical complications is greatly reduced. Common sense aside, one should base their decisions on the actual facts reported by their treatment provider. Overall, the number of complications are generally reported to be less than 1%. Most of the reported problems are handled through laser re-treatments or enhancements.
This article presents a brief overview of some of the potential complications that could result from lasik surgery. While it is rare, patients who have chosen an incompetent LASIK can end up with bigger problems after the surgery. They can have complications as serious as the one described above, or worse, they can lose their eyesight altogether. Make sure that the doctor you get has had a solid reputation of performing successful LASIK operations in the past. It is important that you talk to your doctor extensively when considering lasik surgery so that you have realistic expectations and are aware of the risks and potential pitfalls as well as the upside of laser eye surgery.
Some of the more common types of LASIK complications are improperly formed LASIK flaps: Sometimes after the first surgery, a patient might experience an improperly formed flap. This might create an irregular surface and cause various vision defects. In such cases, LASIK surgery needs to be repeated one or more times to make the eye surface smooth. That’s why you really need to speak to LASIK doctors about these sort of issues to understand the risks involved here.
Dry eye is the most common complication of LASIK. Most patients receive a prescription for eye drops to help lubricate the eyes and prevent infection, but eye drops may not be enough. Dry eye can persist and become painful necessitating further treatment. Corneal nerves that are responsible for tear production are severed when the flap is cut. Medical studies have shown that these severed nerves never return to normal densities and patterns. Symptoms of dry eye include pain, burning, foreign body sensation, and eyelid sticking to the eyeball.
LASIK results in loss of visual quality. After lasik surgery, some patients are left with poor vision at night or in lower light situations. Seeing halos around objects or excessive glare at night are symptoms of this complication. This may stop over time or one may need eyeglasses when driving at night. Have more difficulty seeing detail in dim light (loss of contrast sensitivity) and experience an increase in visual distortion at night (multiple images, halos, and starbursts). A published review of data for FDA-approved lasers found that six months after LASIK, 19.7 percent report glare (starbursts), 17.5 percent of patients report halos, 21 percent complain of eye dryness and 19.3 percent report night-driving problems.
after LASIK, The cornea is incapable. Researchers found that the flap heals to only 2.4% of normal tensile strength. LASIK flaps can be surgically lifted or accidentally dislodged for the remainder of a patient's life. The FDA website warns that patients who participate in contact sports are not good candidates for LASIK.
It is extremely important if you are considering lasik to speak at length with your doctor in order to fully understand the complications that could set in as well as the advantages in order to make the right decision about lasik surgery for you.
