Better Eyesight - Is Lasik Surgery Be the Best Way Or Another Way Better Without Any Dangerous?

Better eyesight with surgery can be a question, if you dare take the risk of jumping from an airplane using a parachute? Ask an optometrist to a patient. He had just asked the doctor removed his glasses and his eyesight corrected through lasik surgery or laser-assisted in keratomileusis (one method of correcting refractive disorders for nearsightedness, farsightedness, and cylinder). millions of North Americans to do the procedure and satisfied with the results. However, the current Food and Drug Administration (FDA) wants a strong warning to the material information to patients about the effects of complications. Exactly the same problem with the parachute failed to open, could have been adverse surgical complications.

Lasik surgery permanently changes the curvature of the cornea, the clear membrane that is located at the front of the eyeball and translucent. A laser device is used to make the incision flap (layer) on the cornea, leaving part of the flap is still attached at the end of the cornea. Then the computer laser vaporize tissue under the flap and then the flap is returned to its original position. Satisfactory results would be so interesting, who does not like a better vision without the use of contact lens or glasses. But so much written about the benefits of lasik surgery that it would be prudent for prospective patients to understand the potential risks.

After surgery, the flap that had been sliced in the cornea and then returned to the original position, may be shifted, causing the problem. The possibility of infection will also occur anytime, anywhere in the incision is made in the body. This may require intensive treatment and may eventually cause temporary vision loss or even permanent blindness. And it is important to remember that the laser machine tool may not always do what they should do. Some patients suffer side effects that damage the quality of their vision has even improved vision acuity. For example, although the eye sight test chart (a test to measure sharpness of vision) showed good results, some patients still can not see in light conditions with low contrast, such as when driving at night or in foggy conditions.

In one 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 short-distance vision (short-sighted) who undergo laser surgery, 80 percent can not see the traffic signs at a distance of 15 cars, and 40 percent do not see the traffic signs at a distance of 4 cars. This is worrying, as a drunken driver. But with millions of people who undergo lasik surgery, need to be asked how many trips will be conducted at night. Moreover, laser surgery can not stop aging, and for the size of our age, night vision, of course, has experienced a decline. This leads to blow (double-whammy). Some post-surgery patients had suffered a loss of quality vision problems such as double vision, or complain of such a blinding circle of light on vision.

May also occur less professional actions or excessive treatment of patients, produce less than 20/20 vision. In one study, 36 percent of those who did surgery on both eyes still need glasses. Other reports claimed that 2 per cent from 10 per cent of people still need glasses after lasik surgery. Others suffer from dry eye syndrome. In this case, the eye is not able to produce enough tears to keep the eye moist. This not only causes discomfort, but sometimes also through obscurity, and this can be a permanent problem since the eye will continue to need regular eye drops.

So what does all this mean? This column is not intended to frighten people who want to perform lasik surgery. This is more of an expression that is wise for patients to follow the advice of the Roman era which has proven its effectiveness in the long term (time-tested), ie "please investigate before you buy" let the buyer be careful. Only, you must be a patient who fully understand the information before agreeing to lasik surgery. And anyone who tells you that there will be no complications, is a liar or a fool.

Decisions even more difficult when lasik surgery is only for convenience rather than out of necessity, given that the majority of cases end with good results. the problem is, you will not know when a rare complication will occur. It is a terrible day when loss of vision occurs simply because you want to get rid of glasses. So you should always be willing to accept the risks when considering lasik surgery. Do not forget that on rare occasions, even a perfect parachute fails to open any can. Better eyesight can still be felt in other ways, namely by eyesight exercises, with the right methods and handling of the expert, you can throw away your glasses without surgery.
