How LASIK Eye Surgery can Help You

Many people speak highly of lasik eye surgery, but there are others who believe it?s a risky procedure that could possibly have devastating consequences. Whatever you decide about having LASIK surgery is a something only you can determine, however it is smart to find out precisely what is involved before making any decisions.

Eye surgery is done on people who have opted to not wear either glasses or contact lenses any more. A medical procedure, LASIK is performed by a authorized eye surgeon. Essentially it changes the shape of the cornea and increases the person's visual acuity. Note that it is not always an unqualified success (however rarely), and there are concerns with long term implications of having this surgery done. As of now though, long term implications seem to be promising with adverse effects seldom being reported.

New and better ways of performing LASIK eye surgery are being continually researched. The main advantage of the laser being used to perform the most delicate part of the procedure is that almost any margin of human error is removed, improving the success rate of the procedure.

The cornea is the part of the eye which focuses light; this light then creates an image on the retina. It actually works much like a camera does when taking a photo. The problem is that this "photo" is not always clear; for many people their eyes are not a perfect lens shape. This is when the images people see become blurred, again much as a photograph is when it is out of focus.

Since light is bent and refracted when sending images from the cornea to the lens of the eye, when it's distorted, they become refractive errors. This is when eye glasses or contact lenses need to be worn usually for the rest of that person's life.

There are three types of refractive errors which can be improved with LASIK surgery: Myopia, Hyperopia and Astigmatism.

Myopia is near sightedness which is when a person has difficulty focusing on anything in the distance.

When someone has Hyperopia, they are far sighted. This means they can see things far away, but have difficulty focusing on anything which is close to them.

Astigmatism occurs when there is a distortion of the image on the retina. These are caused by irregularities in the cornea or lens of the eye.

All three of these eye conditions are quite common, and it is possible to have more than one at the same time. This is where eye glasses and contact lens come into their own. Properly fitted eyewear adjusts for the problems connected with refractive errors and allows the vision to be corrected.

Lasik surgery takes these curative actions a step further, allow vision to be further improved. LASIK surgery can?t always promise 20/20 vision, but it can provide substantial improvements. These can also help in improving a person's self-confidence and quality of life.
