What is refractive surgery? Refractive surgery, otherwise known as LASIK, is a form of operation designed to improve vision by reshaping the cornea in a way which makes reading easier. This article will talk about the benefits of having LASIK and what the price and dangers are.

Lasik surgery is a relatively simple procedure in it is used to correct eyesight. There are two major processes used in Lasik and they are known as refractive surgery and excimer laser operation. Refractive surgery may be used to modify the shape of the retina, by simply creating a curve or by altering the depth of the retina itself. This is carried out by using a microkeratome tool on the patient. LASIK is also a form of excimer laser surgery that involves treating the eye with a low-intensity laser pulse.

When the cornea is damaged, vision loss can lead to dry eye syndrome. The dry eye syndrome is caused when the body reacts to the damage by causing your eyes to tear and the tissues inside the cornea to dry up. When this occurs, the eye becomes unable to provide a protective coating of fluid and the person is subject to serious vision loss.

Refractive surgery may also be used to correct the astigmatism of the eye. Astigmatism affects how the retina appears at an object when you look straight forward. This is also called myopia, which means that the eyeball tilts in the front of the retina when looking straight ahead. Astigmatism is quite common, and it accounts for most of the cases of vision loss of vision in the USA.

In addition to the high amount of complications in the surgery, LASIK also has its own dangers. These include allergic reactions, swelling, and a build up of pressure in the eye. If a flap doesn't close properly after the operation, then the end result is a corneal abrasion. This can cause the formation of tiny tears. If the flap does not shut properly, then the cornea won't heal properly and there is an opportunity of the eye falling out entirely.
