Cataract surgery linked with lessened dementia risk

Based on the longitudinal data of over 3,000 study participants, researchers found that subjects who underwent cataract surgery had nearly 30% lower risk of developing dementia from any cause compared with those who did not. This lowered risk persisted for at least a decade after surgery. Cataract surgery was also associated with lower risk of Alzheimer disease dementia specifically.
