Nevertheless, no therapeutic intervention in medicine is 100% guaranteed, and they may have untoward complications and problems. These operations are no exception to this rule either. Fortunately, most complications of these operations are trivial and transient or treatable. Nevertheless, rarely some complications may develop which due to long-term persistence, they may require corrective measures, and even more rarely their treatment may be hard or even impossible.<\/p>\n<hr>\n<h2>Relatively common complications:<\/h2>\n<p>Although these complications are relatively common, they are not considered as malignant and dangerous complications<\/p>\n<ul>\n<li>Impaired night vision<\/li>\n<li>scatter of light in the night<\/li>\n<li>diplopia and seeing shadows around objects<\/li>\n<li>photosensitivity<\/li>\n<li>cloudiness and blurred vision<\/li>\n<li>sense of dry eyes<\/li>\n<li>constant fatigue and irritation of the eyes<\/li>\n<\/ul>\n<p>Although the above-mentioned complications are relatively common, fortunately in most cases they resolve over time.

The reasons of diminished vision in these patients include mostly unevenness or turbidity of cornea. Cornea unevenness develops in response to different factors such as improper functioning of devices or abnormal course of corneal healing. Laser devices used for these operations are very safe, and they are always controlled and tested carefully. Nevertheless, no technology is ideal and every technology has its own potential problems. The special conditions of the eyes of every person and the course of its healing are also involved in the development of complications. Another reason of the unevenness of cornea is development of keratoconus following the operation. The reason is not very clear, though intrinsic factors as well as the personal and familial predisposition may be involved in it. This complication today is very rare and occurs in less than one per 10,000 cases. Nevertheless, corneal turbidity happens in response to inflammation following the operation or infection.<\/p>\n<p>Although one can mitigate many of the above-mentioned complications through preventive measures, they may rarely happen. Fortunately, by applying newer devices and techniques, the above complications have become far rarer, and in case of incidence, their therapeutic facilities have grown considerably. Nonetheless, the possibility of incidence of these complications still exists, and in case of incidence, although their treatment is possible it is sometimes difficult and will require further therapeutic measures or operations.<\/p>\n<p>We performed a study on a number of patients and found that the chance of diminished vision in response to the above mentioned complications has been less than 1 per 1000. Therefore, concerning these statistics, one can conclude that Lasik operations enjoy high reliability and safety. Further, in a survey we performed on a large number of patients, we concluded that 97% of patients were absolutely satisfied with the outcome of operation, and very few percent of them had minor dissatisfaction.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Eye laser operations such as PRK, trans-PRK, Femtolasik, and others are considered as very safe and effective operations, whose high effectiveness and safety have been proven over a long time.
