The Risks of Laser Eye Surgery

Laser Eye Surgery, and in this case, the best known form of laser-assisted surgery - LASIK, a popular outpatient procedure that corrects the eye refractive conditions like nearsightedness, farsightedness and astigmatism, and even though this kind of operation is basically a short recovery time, low post-operatory is a nuisance to be honest think the risk of interference.Perhaps the most popular eye surgery, LASIK is generally considered risk-free intervention, but before choosing LASIK is the solution to a refractive problem, the weather nearsightedness, farsightedness and astigmatism, one also should be aware of the risks and possible complications of the surgical procedure.

First of all, a very common risk factor for LASIK, the post-operatory infections - usually prologs the healing time and increases the post-operatory inconvenience, however, infection occurs in only 0.1% of cases.
The development of corneal opacity is another rare, post-operatory condition, which involves an abnormal amount of scar tissue formed during the healing process of the cornea, which could result in worse vision than the pre-operatory stage.

The procedure involves the risk of under-correction and overcorrection caused by the unpredictability of the post-operatory response of corneal tissue, and in this case, the patient can choose a different LASIK, or return to the corrective eyeglasses or contact lenses. The risk of a corneal opacity over the other post-operatory complications, which occur in some cases, but can cause serious vision problems, interfere with vision quality, this complication is usually only a second LASIK.

Very rare cases, patients experience a certain type of regression, which means that even if the operation results are positive, the results fade in a relatively short period of time, even in the months following the operation. In these cases, surgery may be necessary. The other problem is seen after the LASIK procedure is called halo effect, the visual distortion can be observed only in low light, which is caused by the untreated peripheral cornea layer, which creates a faint second image, an effect that can lead to reduced night driving.

In addition, the risk is rarely taken into account the possible failure of the equipment, which can lead to aborting the procedure before completion, which can cause further complications. However, this is an extremely rare case, in order to avoid this type of problem, the patient should carefully choose the clinic and the surgeons who work with him.
