“…Some studies described a better (26,27) or worse (28,29) performance of blue-light-filtering IOLs. The majority of the studies, however, did not find any statistically significant differences in comparison with UV-filtering IOL (30)(31)(32) .…”

Purpose:To investigate the possible effect of aspherical or yellow tinted intraocular lens (IOL) on contrast sensitivity and blue-on-yellow perimetry. Methods: This prospective randomized bilateral double-masked clinical study included 52 patients with visually significant bilateral cataracts divided in two groups; 25 patients (50 eyes) received aspherical intraocular lens in one eye and spherical intraocular lens in the fellow eye; and 27 patients (54 eyes) received ultraviolet and blue light filter (yellow tinted) IOL implantation in one eye and acrylic ultraviolet filter IOL in the fellow eye. The primary outcome measures were contrast sensitivity and blue-on-yellow perimetry values (mean deviation [MD] and pattern standard deviation [PSD]) investigated two years after surgery. The results were compared intra-individually. Results: There was a statistically significant between-group (aspherical and spherical intraocular lens) difference in contrast sensitivity under photopic conditions at 12 cycles per degree and under mesopic conditions at all spatial frequencies. There were no between-group significant differences (yellow tinted and clear intraocular lens) under photopic or mesopic conditions. There was no statistically significant difference between all intraocular lens in MD or PSD. Conclusion: Contrast sensitivity was better under mesopic conditions with aspherical intraocular lens. Blue-on-yellow perimetry did not appear to be affected by aspherical or yellow tinted intraocular lens. Further studies with a larger sample should be carried out to confirm or not that hypotheses.

“…Clinical studies have shown that visual acuity, photopic and scotopic, and colour vision performance is essentially the same with BFIOL and UVFIOL implants. [1][2][3][4][5]9,44,45,69 The concerns that clinical imaging and assessment and visual field testing may be affected by implantation of a BFIOL have been shown not to be the case.…”

“…The BFIOL group was noted to have significantly improved contrast sensitivity in the lower to middle frequencies without affecting color vision, and the incidence of photophobia and cyanopsia was less in this group. 61 Niwa et al 62 showed that the BFIOL is associated with better contrast sensitivity in the middle spatial frequencies of 6 and 12 c/deg in photopic and mesopic vision. In addition, the yellow-tinted IOL decreased the effect of central glare on the contrast sensitivity.…”

“…[138][139][140] Previous data have demonstrated that the reaction time in normal subjects to grating stimuli, especially of low contrast targets at intermediate spatial frequencies, improved with the use of yellow filters. 141 The contrast sensitivity of normal observers can be increased with the use of yellow tinted lenses 136 and intraocular lenses, 142 although some authors have disputed this. 143 A study using tinted lenses found that compared with the no filter condition, yellow and orange lenses increased contrast sensitivity.…”

There is increasing interest in the effects of reactive oxygen species ('free radicals') in ageing, both in the body overall and specifically in the eye. Cataract and age-related macular degeneration (AMD) are two major causes of blindness, with cataract accounting for 48 per cent of world blindness and AMD accounting for 8.7 per cent. Both cataract and AMD affect an older population (over 50 years of age) and while cataract is largely treatable provided resources are available, AMD is a common cause of untreatable, progressive visual loss. There is evidence that AMD is linked to exposure to short wavelength electromagnetic radiation, which includes ultraviolet, blue and violet wavelengths. The ageing crystalline lens provides some protection to the posterior pole because, as it yellows with age, its spectral absorption increasingly blocks the shorter wavelengths of light. Ultraviolet blocking intraocular lenses (IOLs) have been the standard of care for many years but a more recent trend is to include blue-blocking filters based on theoretical benefits. As these filters absorb part of the visible spectrum, they may affect visual function. This review looks at the risks and the benefits of filtering out short wavelength light in pseudophakic patients.
