But to their knowledge, nobody had yet looked at the link between cataract surgery and cause-specific rates of death. To this end, they chose to study participants in the WHI because it contains health data that are “not available in other large databases of patients with cataract surgery in the [U.S.]”

A cataract is an eye condition that is common in older people. It develops when the lens of the eye becomes cloudy, resulting in loss of sharpness and blurring of vision. To see clearly, the lens — which focuses light onto the retina — should be transparent.
