Influence of Blue-Light-Filtering Intraocular Lenses on Color Perception and Contrast Acuity

Visual quality assessment in patients with orange-tinted blue light–filtering and clear ultraviolet light–filtering intraocular lenses

“…Similar to our study, the Hoya AF-1(UY) YA-60BB IOL had mostly higher total error scores and partial error scores than a conventional UV light-filtering IOL (eg, Hoya AF-1 (UV) VA-60BB), whereas color discrimination was usually better in the yellow-tinted blue light-filtering IOL (eg, Acrysof SN60AT, Acrysof SN60WF) than in the UV light-filtering IOL (eg, Acrysof SA60AT) (all Acrysof IOLs by Alcon Laboratories, Inc). 29,32,34,36,39,41,42,56,59,60 These findings are in accordance with clinical observations of Wirtitsch et al, 38 who found a statistically significant lower blue-yellow foveal threshold in patients with the Hoya AF-1(UY) YA-60BB blue light-filtering IOL. The detected differences in color perception between the evaluated blue light-filtering IOLs supposedly derive from the different specific transmission characteristics of the included blue light-filtering chromophores.…”

“…Postoperative ( 1,22,29,38,60 Statistically significant between-group differences were found in color vision at the 3-month follow-up visit. The mean total error scores and partial error scores for boxes 1 to 3 and the blue-yellow axis (partial error scores B-Y) were significantly higher in the blue light-filtering IOL group, indicating deteriorated color discrimination compared with the UV light-filtering IOL group.…”

“…1,4,24,25 Although there are anecdotal data available to support these assumptions, the majority of scientific findings on yellow-tinted blue light-filtering IOLs show no clinically significant differences in visual performance under natural lightning conditions compared with conventional UV light-filtering IOLs. 19,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] Commercially available and previously studied blue light-filtering IOLs are mainly equipped with yellow-tinted chromophores. In contrast, Ophtec BV has developed a different type of blue light-filtering IOL, the Oculaid PC 440 Y Orange Series IOL, which is covalently bound with an orange chromophore.…”

Color discrimination by patients with different types of light-filtering intraocular lenses

“…In their study, Mester et al paid specific attention to performance on box 3 and box 4 of the FM 100-hue test and evaluated blue light-related color perception by separately analyzing partial error scores in these 2 boxes. In a study by Wirtitsch et al, 29 a higher foveal threshold was detected in patients with blue light-filtering IOLs using shortwave automated perimetry.…”

Newer Intraocular Lenses in Present Day Cataract Surgery

“…23 Similarly, it has been demonstrated that these lenses provide similar visual acuity, colour vision and CS to a standard monofocal. 25 Furthermore, there are theoretical concerns regarding the effect of blue-and violet-blocking IOLs on sleep patterns, as blocking short wavelength light may affect the circadic cycle. Until extensive, prospective, randomised, long-term studies examine the effect of blue-/violet-blocking lenses on the development of AMD, their use will remain controversial and debatable.…”
