Macula May Not Benefit From a Blue-Light Filtering Intraocular Lens
Inserting a blue light-filtering IOL during cataract surgery may not benefit the macula, researchers say, according to a Reuters report.
“It has been suggested that IOLs that selectively attenuate short wavelength visible light (blue light-filtering IOLs) may be beneficial for macular health,” note Dr. Laura Downie of the University of Melbourne in Parkville, Australia and colleagues. “Whether blue light-filtering IOLs impart retinal photoprotection is of public health relevance, particularly in the context of aging demographics and the increasing global prevalence of age-related macular degeneration.”
This past May, Dr. Downie was the lead author on a Cochrane systematic review that examined this issue (http://bit.ly/2NyibLC). More recently, in a paper published February 21 online in JAMA Ophthalmology, she and two other colleagues analyzed the key findings of that review.
