Cataract is derived from a Latin word meaning waterfall due to whitening of the pupil. It refers to the opacity of the lens which can lead to vision problems and disorders. Several factors contribute to development of cataract including aging (the most common), genetics, trauma, congenital conditions, smoking, diabetes, and UV. Symptoms of cataracts include blurred vision, photosensitivity, discoloration, or diplopia (double vision). In the early stages, glasses can reduce the cataract-induced vision problems, but surgery is necessary to improve vision in the later stages of the disease. Currently, cataract surgery is one of the most common and successful operations performed under local anesthesia.
The progression of cataracts varies from person to person, and people over the age of 50 can be treated in a timely manner by an ophthalmologist, otherwise a small number of patients may experience increased intraocular pressure (glaucoma), and as a result require emergency surgery, the complications and risks of which are greater than normal surgery.
