Study: IOL color has no effect on sleep, mood
PARIS — Yellow blue-blocking intraocular implants have no impact on sleep and mood, according to a study presented at the meeting of the French Society of Ophthalmology. “There has been discussion on the impact of cataract surgery and intraocular implants, particularly blue-blocking implants, on sleep and mood. Some authors hypothesized that modifications of the light spectrum entering the eye through the IOL might alter melanopsin secretion, melanin production and the circadian rhythm. However, nothing so far has been proven,” Olivia Zambrowski, MD, said.
