A cataract is a condition which causes clouding of the lens in the eye, resulting in blurry vision. The normal lens is usually not visible because it is transparent and situated behind the iris, the dark portion of the eye. The lens is mostly made up of water and proteins. These specific proteins provide the lens its transparent structure. Any change in these proteins can alter the clarity of the lens and negatively impact vision. The lens becomes cloudy when a cataract occurs and may be seen as a white cloudy ball in the center of the iris.

The development of a cataract is common in aged individuals due to changes that occur in the structure of the lens proteins. Cataract can also be inherited or can develop in infants as a result of infections in the mother during pregnancy. They can form as a complication of other diseases such as glaucoma and diabetes, or can develop after certain injuries. Prolonged use of corticosteroid inhalers and eye drops, and excessive exposure to UV rays, X-rays and other radiation during radiotherapy, can increase the risk of cataract formation.
To assess the impact of the cataract on your vision, your doctor will perform a Visual Acuity Test where the patient reads an eye chart from a particular distance with one eye at a time. The doctor then examines the cornea, iris, and lens to detect any abnormalities.
Surgery is the only treatment for cataract and is recommended based on the severity of the disease and the impact it will have on the daily activities of the patient.
