Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Two very common aging-related diseases in older adults are Alzheimer's disease (AD) and cataracts. In elderly adults, these two diseases frequently occur in the same person. Although a cure for AD is currently unavailable, cataracts can be effectively treated with surgery in most people. The removal of cataracts has documented benefits for visual performance and for reducing accidents and falls. However, it has been the experience of the ophthalmologists, and others in the field, that patients, caregivers, and primary care doctors are reluctant to proceed with cataract surgery once an individual is given the diagnosis of AD. It is thought that cataract surgery will not improve the AD patient's quality of life, vision, and cognition. The investigators have designed this study to determine whether or not this is true.
