Comparison of color perception after tinted blue light–filtering and clear ultraviolet-filtering intraocular lens implantation

Abstract

There was no difference in color perception between the 2 IOLs irrespective of the color vision test used.

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.…”

“…Our results are consistent with those in the current literature, which reports comparable visual acuity data between yellow-tinted blue lightfiltering IOLs and clear IOLs that filter UV light only, indicating that the orange-tinted blue lightfiltering effect might also be minimal to clinically insignificant. 5,20,24,34,36,37,[39][40][41][42]47 This is not particularly surprising, especially in regard to photopic vision, which relies on 3 cone receptor types with overlapping sensitivity ranges and a maximum efficacy at approximately 555 nm. At this wavelength, the blue light-filtering IOL displayed transmittance rates of approximately 80%, comparable to that of a middleaged human lens.…”

“…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.…”

Neutralization method for detecting the incidence of color perception changes after cataract surgery

“…Most did not find a change in color vision after the implantation of this type of IOL. [13][14][15][16][17][18][19][20][21][22] In contrast, other studies 4,7-12 report some changes in color perception with some models of yellow IOLs. However, to this date, few studies have evaluated the effect of yellow IOLs on the incidence of cyanopsia compared with clear IOLs.…”

“…These include the potential side effects of blue light-filtering on contrast sensitivity, 4,6 color perception, 4,7-12 and even on circadian rhythm. 1 Several studies 2,4,[6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] have evaluated the effect of a yellow IOL on color discrimination after cataract surgery. Most did not find a change in color vision after the implantation of this type of IOL.…”
