Lasik Plus

There are many people who swear by lasik eye surgery, yet there are others who feel it is a risky procedure which would possibly have far reaching consequences. Whether you decide to have LASIK surgery is a decision only you can make, however it is wise to know exactly what is involved before making any decisions.

Eye surgery is performed on people who have decided they do not wish to wear either glasses or contact lenses any more. LASIK is a medical procedure which is performed by a qualified eye surgeon. Basically it alters the shape of the cornea in the eye and improves the person’s vision. However it is not always an unqualified success (however rarely), and there are concerns as to the long term implications of having this surgery done. So far though, long term implications seem to be promising with ill effects rarely being reported.

New and superior ways of performing LASIK eye surgery are being discovered all the time. A laser is used to perform the most delicate part of the procedure which means a lot of human error is removed. This improves the success rate of the procedure and helps reduce the margin for error.

The cornea in the eye focuses light; this light then creates an image on the retina. It actually works very much as a camera does when taking a photo. Unfortunately this “photo” is not always clear because for many people their eyes are not a perfect shape. This is when the images people see become blurred. (Again this is much as a photograph is when it is out of focus).

Because 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.

They are:-

Myopia
hyperopia
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 very 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. Correctly fitted eye wear compensates for the problems associated with refractive errors and allows the vision to be corrected.

Lasik surgery takes these corrective measures one step further and allows the vision to be much improved. LASIK surgery doesn’t always give 20/20 vision, but it can make vast improvements which can then assist in improving a person’s confidence and quality of life.
