 Generally chances of complications after a eye surgery is about 5%. That might be a vary low number, but still there are risks. It has been observed that most of the complications arise out of the surgeon's inexperience. As the experience of the surgeon increases, the cases of complications decrease. Of course there are other factors which can cause complications.
These would include excessive farsightedness, nearsightedness or astigmatism; large pupils (if the diameter of the pupil is greater than the zone to be treated then undergoing LASIK surgery can cause vision impairment, especially under low light conditions); dry eyes before operation; history of eye diseases like keratoconus. Here we will discuss some of the complications.

The capacity to distinguish an item from its neighboring backdrop is a problem of contrast sensitivity. The reduction in contrast sensitivity is a comparatively common occurrence after eye surgery, particularly in patients with high amounts of myopia.
After surgery almost all patients experience some degree of contrast sensitivity, but that goes away in the first few weeks or months after the operation. |

This eye surgery is used to cure three main types of eye conditions-myopia, hyperopia and astigmatism. Myopia, also know as nearsightedness is the problem of not being able to see what is far away without glasses. Hyperopia, also known as farsightedness, is the other way round. Astigmatism is something different where the patient has irregularities in his cornea which as a result distorts the image formed on the retina of the eye. The complications that one can face after surgery are discussed below.
