What is refractive surgery? Refractive surgery, otherwise known as LASIK, is a form of operation designed to enhance 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 cost and risks are.

Lasik surgery is a fairly straightforward procedure in it is used to correct vision. There are two big processes used in Lasik and they're known as refractive surgery and excimer laser surgery. Refractive surgery can be employed to modify the shape of the retina, either by creating a curve or simply by changing the thickness of the retina itself. This is carried out by using a microkeratome instrument on the individual. LASIK is also a kind of excimer laser surgery that involves treating the eye with a low-intensity laser pulse.

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

Refractive surgery can also be used to correct the astigmatism of the eye. Astigmatism affects how the cornea looks at an object when you look straight forward. This is also known as myopia, meaning that the eyeball tilts in the front of the retina when looking straight ahead. Astigmatism is very common, and it accounts for most of the cases of vision loss of vision in the USA.

Along with the high degree of complications from the surgery, LASIK has its dangers. These include allergic reactions, swelling, and a build up of stress in the eye. If a flap does not shut properly after the operation, then the result is a corneal abrasion. This can lead to the creation of little tears. If the flap does not close correctly, then the cornea won't heal properly and there is an opportunity of this eye falling out entirely.
