What Are Cataracts?
A disease becomes a serious health concern, for medical professionals and the risk population if; it has an increased prevalence, and if it is related to significant morbidity or mortality. Cataract shows both these features. It is therefore insightful to educate masses regarding this disease, which is the leading cause of preventable blindness.
Definition
By definition, cataract is the condition characterized by clouding of the normally clear and transparent natural lens of the eye, leading to vision problems and may eventually cause blindness. The disease follows a slow, progressive course. It can be unilateral or bilateral condition. A cataract in one eye also does not cause the other normal eye to become cloudy.
Our eyes have inbuilt lenses, which serve a major function in refracting light rays as they enter the eye to focus the image on the sensory layer of the eye. In doing so, the lens achieves a single unified, clear image on the retina. This functionality of the lens is significantly dependent upon its structure.
