Comparison of visual performance with blue light–filtering and ultraviolet light–filtering intraocular lenses

Abstract

The yellow-tinted IOLs were equivalent to the clear IOLs in postoperative contrast sensitivity, visual acuity, and color perception under photopic conditions. Patients with yellow-tinted IOLs made statistically significantly more mistakes in the blue range under dim light than patients with clear IOLs.

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

“…Overall, there were no statistically significant differences between the 2 study groups. Our results are in accordance with the majority of previous clinical trials,35,36,40,41,59 which report comparable contrast sensitivity values under photopic lighting conditions in patients with yellow-tinted blue light-filtering and conventional UV light-filtering IOLs. There are few reports indicating potential advantages of one or the other IOL type (yellow-tinted IOL versus UV light-filtering IOL) at low and high spatial frequencies.…”

“…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.…”

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

“…The majority of clinical trials report comparable results for yellow-tinted and UV light-filtering IOLs regarding visual acuity data 3,12,14,30,32,33 as well as contrast sensitivity values. 15,31,[34][35][36] Color perception testing mostly showed higher error scores with yellowtinted IOLs than with UV light-filtering IOLs, whereas in color discrimination, yellow-tinted IOLs usually performed better than UV-light filtering IOLs. 8,14,15,30,34,36 These findings are in accordance with those in a previous study by our group 22 that found a significantly lower blue-yellow foveal threshold in patients with a yellow-tinted IOL.…”

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

“…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.…”
