Cataract Removal and Alzheimer's Disease

Start: June 2009
End: March 30, 2017
Enrollment: 210

What Is This Study About?

The removal of cataracts can improve vision and reduce accidents and falls. However, some individuals, caregivers, and primary care doctors are reluctant to proceed with cataract surgery once an individual is diagnosed with Alzheimer's disease because they think that cataract surgery will not improve the person's quality of life, vision, and cognition. The investigators have designed this study to determine whether or not this belief is true.
