Laser technology has, without a doubt, revolutionised the manner in which operations are conducted. Lasik (a contracted term for laser assisted in situ keratomileusis) is a procedure that is widely practiced by eye surgeons to correct abnormalities of visual acuity. Examples include presbyopia, long-sightedness (hyperopia) and short-sightedness (myopia). If they wish to have Lasik eye surgery San Antonio residents need to have some important information beforehand.
If a decision to have the operation has been made, you need to start the process of preparation. If you are on any blood thinners or aspirin then you need to stop them before you undergo the operation. This is done to minimize the risk of bleeding. Smoking also increases this risk and should also be stopped not later than two weeks before the surgery.
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 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.
