Abstract
Objective: Expand knowledge about cataracts. Bibliography review: Cataract is a disease resulting from opacification of the ocular lens that can affect children, adults and the elderly, being more common in elderly people. The disease hinders the penetration of light into the eye and consequently the formation of an image on the retina, often causing serious problems for people affected in the development of their daily activities. In the presence of visual changes, the patient should seek an ophthalmologist for specific exams. The treatment for cataracts can vary from clinical, only using corrective lenses or it can be surgical. Final considerations: Cataract is a vision problem that can occur with amaurosis, significantly compromising the quality of life of the individual who has the disease. Therefore, in the presence of suggestive visual symptoms, the patient should seek an ophthalmologist for diagnosis and establishment of a therapeutic plan according to the needs of the case.
