Basic Facts about Cataract Surgery


Hi Neighbors!

A cataract is cloudiness in the lens of the eye that is caused from a buildup of protein. The cloudiness keeps light from going through the lens, which can cause loss of vision. Cataracts are often a result of aging, but can also be caused by infection, injury, diabetes, drugs, radiation, or trauma to the eye. Cataract surgery in Cary can easily take care of this problem and restore vision once again.

Surgery Preparation

In preparation for this surgery, the patient may be asked to stop taking certain medications, especially those that may cause extra bleeding. Tests will be performed in order to determine the right lens that will be implanted. The procedure itself is rather quick. Eye drops will be used to dilate the eye, and local anesthetics will numb the area. If necessary, sedatives can be given to help the patient relax. The patient is awake throughout the procedure, which usually takes an hour or less.

Phacoemulsification

This procedure is what breaks up the cataract and the lens in order for it to be removed. An incision is made in the front of the eye, which is small enough to insert a probe the size of a needle. This probe sends out ultrasound waves which break up the cataract and suction out the pieces. The back of the lens stays in place so that the artificial lens has somewhere to rest. This procedure can even be done without stitches, although some doctors may choose to close the small incision.

Extracapsular Cataract Extraction

This procedure is a less-used alternative to phacoemulsification. A larger incision is made and surgical tools are used to remove the lens. Suctioning tools are used to remove the cataract fragment and the rest of the lens. Stitches are usually required for this type of procedure. 

Lens Replacement

Finally, an artificial lens is implanted. It is usually made of plastic, silicone, or acrylic. There are lenses available that are flexible enough to fit through a small enough incision that won’t require stitches. There are different types of lenses available in cataract surgery in Cary. Some lenses can work like bifocals for near and distant vision. Other lenses can block ultraviolet light. There are even lenses available that can correct astigmatism.
