Lasik is a surgical treatment for the correction of impaired vision. This relieves the patients of the burden of wearing glasses and contact lenses. Lasik (laser in situ keratomileusis, for full) is a relatively new procedure started in the last decade. The technique corrects the imperfections of the eye by altering the shape of the cornea using laser technology. It is mainly used for the correction of refractive errors such as myopia, hyperopia, astigmatism and their combinations.

The process of lasik surgery starts with cleaning of the eye. The patient feels no pain, since anesthetic eye drops are applied on the eye. An instrument called a microkeratome is used to create a thin, circular flap in the cornea. The flap is then folded on the hinges and the middle potion of the cornea, called stroma, is revealed. The cornea is reshaped by vaporizing the exposed tissue using the pulses of an excimer laser. This complex procedure is performed accurately using automated tools.

Lasik surgery will take only 10-20 minutes. The patients can rejoin their work even the next day. However, adequate rest is recommended to avoid any complications. More than 95% of the patients are usually satisfied with the results of the treatment. Most of them can achieve 20/20 vision within 6 months. The results of the treatment are permanent. The selection of a qualified ophthalmologist with adequate experience is necessary to achieve the expected results.

A low percentage of the patients experience dry eyes, infection, light sensitivity etc. Patients with certain diseases are not permitted to undertake the surgery. Lasik surgery may not be effective in certain cases such as presbiopia, hyper correction of the cornea etc.

Lasik information is mostly available from health magazines and Internet sites. Books and articles can also provide adequate information. A thorough understanding of the subject will help you take necessary care during the pre and post surgical periods.
