Cataracts, Cataract Surgery, and Cognitive Function

Cataracts are a common age-related eye condition that causes clouding of the eye’s natural lens, leading to decreased vision. While cataracts can often be successfully treated with surgery, recent studies have investigated the relationship between cataracts and cognitive function.

One study published in JAMA Ophthalmology found that individuals with cataracts who underwent cataract surgery had a slower rate of cognitive decline compared to those who did not have surgery. The study followed over 2,000 adults aged 65 and older for up to 10 years and found that those who had cataract surgery had significantly less cognitive decline compared to those who did not.

Another study published in the Journal of the American Geriatrics Society found that older adults who underwent cataract surgery had a lower risk of developing dementia compared to those who did not have surgery. The study followed over 250,000 adults aged 65 and older for up to 5 years and found that those who had cataract surgery had a 50% lower risk of developing dementia compared to those who did not have surgery.

While more research is needed to fully understand the relationship between cataracts and cognitive function, these studies suggest that treating cataracts with surgery may have benefits beyond just improving vision. However, it is important to note that cataract surgery, like any surgical procedure, does carry potential risks and complications, and individuals considering the surgery should discuss the potential benefits and risks with their healthcare provider.
