What The Study Did: The secretion of melatonin is an important indicator of the body’s circadian rhythm. An internal circadian rhythm misaligned with the outside world and a low concentration of melatonin secretion have been associated with risk for a variety of diseases. This randomized clinical trial investigated whether cataract surgery, which increases a person’s perception of light, affected melatonin secretion in patients 60 and older having their first cataract surgery compared with those whose cataract surgery was delayed.
