Do Blue-Light Filtering Intraocular Lenses Affect Visual Function?

“…A recent study with similar design and results had an even smaller sample size of 22 patients. 43 For macular evaluation, besides OCT and clinical evaluation, fundus autofluorescence (FAF) may be used to provide additional information not obtainable with other imaging techniques. It is known that FAF changes in ARMD do not correlate with clinically visible alterations, and it was assumed that abnormal FAF reflects more widespread macular changes.…”

Rejuvenation Effects of Cataract Surgery with Ultraviolet Blocking Intra-Ocular Lens on Circadian Rhythm and Gait Speed

“…4 The clear, ultraviolet (UV)-blocking and the yellow-colored IOLs currently available show similar properties in terms of visual function with the exception of vision in mesopic or scotopic light conditions. [5][6][7][8][9] Glare reduction is an additional advantage of yellow-colored IOL, although concerns have been raised that the blue lightblocking effects of such a lens might disturb normal circadian rhythms 10,11 because intrinsically photosensitive retinal ganglion cells mediate melatonin secretion by photoreception of blue light. [12][13][14] On the contrary, clear IOLs do not block visible light transmission and thus offer no protection to the retina from the potentially damaging effects of bright light, [15][16][17][18][19][20] although the protective effect of a blue lightblocking IOL is elusive.…”

Influence of light filters in intraocular lenses on color perception and contrast acuity

“…However, Schmack et al 37 reported similar results after implantation of an orange-tinted IOL and a clear UV lightfiltering IOL. They report comparable postoperative visual function except for color perception, which was slightly better in eyes with a clear IOL.…”
