Sunlight Exposure and Risk of Lens Opacities in a Population-Based Study

Abstract
DESPITE ADVANCES in surgical procedures and targeted programs, cataract remains the leading cause of visual loss worldwide.1 In the United States, cataract surgery is responsible for 12% of the Medicare budget,2 or $3.4 billion annually in 1991. Although cataract surgery rates have increased, there are still underserved minority populations where cataract remains an important cause of visual impairment (data available from authors).3 As the population ages, both in the United States and globally, cataract surgery and loss of vision from cataract will become an even more pressing issue for the eye care community.
