A cataract is a clouding of the natural lens of an eye that lies behind the pupil and the iris. They develop fairly slow and can affect one or both the eyes of a person. Cataracts can lead to a decrease in the vision and a person might have to face significant problems in recognizing faces, reading and driving due to them. Poor eyesight caused due to cataracts may also increase the risks of falling down and tripping. They are the cause of a major percentage of visual impairment across the world.
Cataracts can be broadly categorized into three types. They are:
- Subcapsular cataract – This type of a cataract occurs at the back of the lens. Individuals taking high doses of steroid medications or suffering from diabetes have a higher risk of developing a subcapsular cataract.
- Nuclear cataract – This type of a cataract forms deep in the nucleus or the central zone of the lens. Nuclear cataracts are mostly associated with old age.
- Cortical cataract– This type of a cataract are characterized by wedge-like while opacities, which start in the periphery of the lens. These opacities gradually work their way to the center in a spoke-like manner. Cortical cataract occurs in the lens cortex that is the part of the lens surrounding the central nucleus.
