Lee CS, Gibbons LE, Lee AY, et al. - Findings imply that cataract extraction is linked with lower risk of developing dementia in older adults.

• This is a cohort study evaluating 3038 adults 65 years of age or older with cataract enrolled in the Adult Changes in Thought study.

• A lower risk (hazard ratio, 0.71) of developing dementia was found in participants who underwent cataract extraction vs those who did not have cataract surgery after controlling for numerous additional risks.

• In comparison, no difference in the risk of dementia was observed between participants who did or did not undergo glaucoma surgery, which does not restore vision (hazard ratio, 1.08).
