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.
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.
Most of the problems of visual acuity are related to an abnormal corneal curvature. The cornea is the transparent part found in front of the eye lens. It facilitates the refraction of incident rays of light so that they can project onto the retina. Readjusting the curvature can alter the angle of refraction and consequently the site on which the image will be formed.
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 technique called wave front has been adopted to help minimize unnecessary corneal damage. The technique helps surgeons locate the areas with the problem with more precision and then focus on these areas with laser. Once the area has been identified, a flap is created to access the underlying tissues (also known as the stroma). The next step is to vaporize the stroma using a laser beam.
There are a number of complications that may arise from this surgery. The commonest problem is dryness of the eyes. It is most likely to be seen after about six months after the operation. The management options here include the use of prescription tears and a minor procedure known as punctual occlusion. Other possible complications include double vision, increased sensitivity and infections.
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.
