One of the most important developments in eye surgery is the adoption of laser techniques which have reduced the complications and improved the outcomes. Lasik which is the abbreviation for laser assisted in situ keratomileusis, is a surgical procedure that is used in the management of visual errors such as astigmatism, short-sightedness (myopia), long-sightedness (hyperopia) and presbyopia. Before undergoing Lasik eye surgery San Antonio residents should know a number of things.
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.
There are several complications that may be encountered when undergoing this procedure. Dryness of the eyes is among the commonest. It occurs several weeks following the surgery. Fortunately, it resolves spontaneously a few days later. In the event that it persists, your doctor will prescribe artificial tears and may perform a procedure called punctual occlusion. Other complications include increased sensitivity to light, double vision and infection.
Lasik is a safe and effective surgical procedure that is used in managing visual abnormalities. Most persons (about 98% of those operated) report improvement within a few days of having the operation. Remember that the degree of improvement will vary from one person to another depending on factors such as the severity of the initial problem and the skill of your surgeon.
