Cataracts are common in older people and over half of people in the United States have cataracts or have undergone cataract surgery by the time they’re 80 years old. In this session details will be discussed about the causes and types of cataract such as age-related cataracts, congenital cataracts, secondary cataracts, traumatic cataracts, nuclear cataracts, cortical cataracts and posterior sub capsular cataracts.
