A new study indicates that cataract surgery may help people beyond giving patients better vision. Research published in JAMA Ophthalmology shows that patients with new lenses following cataract surgery got more REM sleep or deep sleep. They also did better on cognition tests. The findings suggest that the amount of light entering the eye regulates the internal clock of humans.

“The main take home message is that cataract lens replacement may be associated with improved circadian rhythms, better cognitive performance and improved sleep,” said the study’s lead author, Dr. Sarah Chellappa, of Harvard Medical School in Boston.
