The Basic Facts About Lasik Eye Surgery San Antonio Residents Need To Have

By Frances Long


The adoption of laser technology in eye surgery has revolutionized the field. Complex operations can now be done easily with very few complications. Lasik, laser assisted in situ keratomileusis, is one of the most useful procedures. It is mainly used in the correction of visual acuity disorders such as myopia (short-sightedness), astigmatism, presbyopia and hyperopia (long-sightedness). If they plan on undergoing Lasik eye surgery San Antonio clients need to understand a number of things beforehand.

There are a number of things that have to be done as one prepares for the operation. Many of them are similar to what is required during a major operation. For instance, one is required to stop taking any blood thinners if they are part of their regular medication. If they are smokers, they should stop around the same time. All these are aimed at reducing the risk of bleeding.

Ophthalmic examination is another important component of the preparation process. The examination helps to evaluate the exact disorder that is involved and its severity. This is what will help the surgeon decide on what exactly they are going to do. You will also be informed on the possible risks and the chances of succeeding. Persons that have extreme myopia or very thin corneas are usually excluded if found.

All the corrections needed are achieved through alteration in the shape of the cornea. The cornea is a region in front of the eye just overlying the lens. A change in the curvature of the cornea alters the angles of incidence and refraction as desired. Consequently, visual acuity is improved. In the event that there is any excess corneal tissue, it is removed through a process known as ablation.

The surgery can be performed safely in an outpatient department of a hospital or clinic. This is because local anesthesia or light sedation is usually sufficient to reduce the discomfort. You will be placed on the operating table and asked to lie on your back. You will then be instructed to gaze on a specific object as the surgeon starts to operate. The strength of laser needed is usually calculated by a computer.

A modern technique known as wave front has been adopted by most surgeons and is becoming routine practice. The technique is used in locating the areas that require correction with great precision hence avoiding unnecessary injury to other areas. This is done through two stages. The first is the creation of a flap of corneal tissue. This is followed by vaporizing the tissues underneath the flap using the laser.

The surgery may cause a number of complications. Itchiness and increased dryness of the eyes are particularly common. Dryness may be seen up to six months following the procedure. Most cases will resolve spontaneously with just a few of them persisting. Artificial tears or the punctual occlusion procedure may be used to relieve the symptoms. Other possible complications are infections, increased sensitivity to light and double vision among others.

Lasik is one of the most effective techniques used in correcting abnormalities in visual acuity. Close to 98% of persons undergoing the procedure report of a marked improvement in their vision. The maximal results will be seen at about two months. Success varies and id determined by the magnitude of the problem as well as the skill of your surgeon.
