Cataract Extraction

A cataract is an eye disease in which the normally clear lens of the eye becomes cloudy or opaque, causing a decrease in vision

Cataratas

The lens is important for focusing light onto the back of the eye (the retina) so that images appear clear and without distortion, and the clouding of this lens during cataract formation distorts our vision. Cataracts are usually a very gradual process of normal aging but can occasionally develop rapidly. They often affect both eyes, but it is not uncommon for a cataract to advance more rapidly in one of the eyes. Cataracts are very common, affecting roughly 60% of people over the age of 60.

The precise reason why cataracts occur is unknown; however, most cataracts appear to be related to changes in the protein structures within the lens that occur over many years and cause the lens to become cloudy. Rarely, cataracts can occur at birth or during an early childhood stage as a result of hereditary enzyme defects, a genetic disease or systemic congenital infections. Severe trauma to the eye, eye surgery, or intraocular inflammation can also cause cataracts to develop more rapidly. Other factors that may lead to development of cataracts at an earlier age include excessive ultraviolet light exposure, exposure to ionizing radiation, diabetes, smoking, or the use of certain medications, such as oral, topical, or inhaled steroids. Some medications can be (weakly) associated with cataracts, such as a long term use of statins and phenothiazines.

When people develop cataracts they begin to have difficulty doing some activities that require clear vision, like driving at night, reading, or traveling. Therefore a consultation with an eye surgeon is recommended.
