Can Cataract Surgery Prevent Dementia?

Cataract surgery is a highly successful procedure that removes the cloudy lens of the eye and replaces it with a clear artificial one. But researchers are now finding that restoring clear vision may have benefits that go well beyond sight.

Is There a Link Between Cataracts and Dementia?

More than half of people aged 80 or older have had at least one cataract, and many in this age group also have dementia. A 15-year study found that patients with age-related vision problems, including cataracts, had an 11% higher incidence of dementia compared to patients with healthy vision.

Can Cataract Surgery Lower Dementia Risk?

Research suggests it might. A 2022 study published in JAMA Internal Medicine found that patients who underwent cataract surgery had a 29% lower rate of dementia compared to those who did not. MRI scans have also shown greater brain activity following cataract surgery.

How Might Vision Loss Contribute to Cognitive Decline?

Scientists believe that the more visual information the brain receives, the more active and stimulated it remains — which may help fend off dementia. Additionally, significant vision loss often leads to social isolation, which is independently linked to a higher dementia risk.
