Healthy Diets and the Subsequent Prevalence of Nuclear Cataract in Women

Abstract
Cataracts, which increase in prevalence with age, are the most important cause of blindness in the world.1 In the United States, cataract is the most prevalent cause of visual impairment due to eye disease,2 and surgery to remove lenses with cataracts accounts for approximately 60% of vision-related Medicare expenditures.3 The number of Americans affected by cataract and undergoing cataract surgery is expected to increase dramatically in the next 20 years as the US population ages.4 As more aging Americans need cataract surgery, there is concern about the ability of health care systems, particularly Medicare, to fund cataract surgery.3 Therefore, identifying modifiable risk factors is of critical importance to improving health of older Americans and to the economic stability of the health care system.
