The Risks of Laser Eye Surgery

Millions of people around the world are forced to wear glasses or contact lenses in order to see clearly. These people may have heard about the option of having laser eye surgery to correct their vision problems. While these procedures are relatively safe, they still carry risks as all surgery operations do. This article will share with you some of the most common risks.

Severe Dry Eye Syndrome

It is normal for most patients undergoing laser eye surgery to experience gritty or sandy feelings in the eye following the procedure. This condition usually goes away within the first three months. For some patients, it may be permanent. After the surgery, the eye may not be able to keep the eye moist by producing enough tears. This may require another procedure to block the tear drainage canals with plugs. This prevents tears from draining away so quickly, resulting in improved lubrication of the eye.

Undercorrection/Overcorrection

With laser eye surgery, there is always the possibility that the surgeon reshapes the cornea too much or not enough. This overcorrection or undercorrection is usually temporary, but in some cases can be permanent. If it has not resolved after a month or so, the surgeon may elect to perform an enhancement procedure. It is not unusual for patients to still have to wear glasses or contact lenses after surgery.

Induced astigmatism

Astigmatism is a condition that results in distorted vision when trying to focus on objects at a distance. Although it is rare, laser eye surgery can induce astigmatism in patients. If this happens, an enhancement procedure may be require to correct the problem.

Corneal Ectasia

Corneal Ectasia is a very serious condition. This occurs after laser eye surgery when excessive thinning weakens the cornea. The internal pressure of the eye then causes bulging of the cornea. A corneal transplant or implant may be needed to treat severe cases of this condition.

Loss of vision

There are a number of complications with laser eye surgery that can result in a loss of vision. Inflammation or infection of the cornea may require intensive treatment with eye drops or another surgery. It is possible to lead to irreversible blindness even with aggressive treatment.

Laser eye surgery are usually very safe surgeries. But as with all surgeries, there are risks you should be aware of. Before deciding if this procedure is right for you, you should have a thorough talk with your surgeon.
