Abstract
Age-related cataract is one of the most important eye diseases leading to blindness and visual impairment worldwide. Epidemiologic studies had shown that the prevalence and incidence of age-related cataract were relately high and varied among groups with different age, gender, region and race. Various types of cataract were associated with different factors including age, sex, smoking, diabetes mellitus and estrogen. Age-related cataract was still a severe public health problem for elderly, women and illiterate groups. Although great progress had been made in the diagnosis and treatment of cataract, the cataract surgery rate in China remained low, and the project of vision restoration from cataract still had a long way to go.
