If a disease is associated with significant morbidity and mortality, or if its prevalence increases, it becomes a health concern for medical professionals. Cataracts show both of these characteristics. This disease is the most common cause of preventable blindness.
Cataract is a condition that causes clouding in the natural, transparent lens of the eyes. This can cause vision problems, and even blindness. The disease progresses slowly. The condition can be bilateral or unilateral. The cloudiness of the normal eye does not occur when one eye has a cataract.
The lenses in our eyes are designed to help focus images on the retina. The lens creates a clear, unified image on the retina. The structure of the lens has a significant impact on its functionality.
