Effect of a yellow intraocular lens on scotopic vision, glare disability, and blue color perception

Abstract

The AcrySof SN60AT Natural IOL provided contrast sensitivity under photopic and scotopic conditions (with and without glare) and blue color perception comparable that obtained with the AcrySof SA60AT IOL. Scotopic vision and blue color discrimination decreased with age with both IOLs.

Measurements of transmission spectrums and estimation of retinal blue-light irradiance values of currently available clear and yellow-tinted intraocular lenses

“…A more recent study claims that the visual function in eyes with yellow-tinted IOLs did not differ significantly from eyes with clear IOLs regarding their photopic and mesopic contrast VA both with and without a glare source [33]. Other studies report decreased blue color perception [34] or photoreception [16] with yellow-tinted IOLs. Thus, when vision photoprotection is referred to, photoreception must always be taken into account [35,36].…”

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

“…[51][52][53][54] These considerations were corroborated by recent studies showing reduced scotopic sensitivity of 15% to 21% by yellowtinted blue light-filtering IOLs. 5,20,24,35,55 In addition, case reports have shown color disturbances by the use of blue light-filtering IOLs, occasionally resulting in IOL exchange. 56,57 On the other hand, there are also indications that tinted IOLs, especially yellow and orange lenses, increase contrast sensitivity at middle and high spatial frequencies.…”

“…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.…”

Ultraviolet or blue-filtering intraocular lenses: what is the evidence?

“…44 Futhermore clinical, non-theoretical studies investigating scotopic sensitivity did not find any difference between these two IOL groups. 45,46 A study was carried out by Kiser et al, using an external filter with simulated blue-light filtering in patients with bilateral pseudophakia with UVFIOLs whose average age was 81 years old, and who had early AMD. Their performance was tested by observation of walking through two different mobility courses in scotopic conditions.…”
