Lasik refers to a refractive laser surgery performed on eyes of the person suffering from myopia, hyperopia or astigmatism. This surgery is very convenient for a patient as it takes comparatively less time and the patient does not feel much pain. Many people prefer this kind of surgery over wearing eyeglass or contact lenses. Lasik technique is a type of surgery which is very cost effective and can be done in a very short time period. Nowadays, this type of eye surgery is well performed in Lasik vision institute.

This technique of Lasik was first introduced by a Spanish ophthalmologist and in 1960, he developed the first microkeratome. At that time it was used to cut thin flaps in the cornea region and to change its shape. In the year 1990, Lasik surgery was developed and it rapidly became popular due to its reward of greater precision and less complications. With more investigation, this surgery has become very common and has significantly improved the procedure of surgery. In almost every country people have started to see this surgery as a new ray of optimism for the correction of eye defects.

Before conducting the surgery, the patients' corneas are examined with the help of a pachymeter to ascertain its thickness and with a topographer to measure surface contour. This also enables the surgeon to notice astigmatism and any other irregularities in the cornea. After the surgery, patients have to undergo a course in antibiotics and put anti-inflammatory eye drops for some time. Patients are advised to wear a dark pair of eyeglasses to protect it from light after Lasik surgery.
