The use of tinted intraocular lenses (IOLs), such as the AcrySof Natural "yellow" tinted lens (SN60AT) has led to questions regarding possible adverse effects on visual performance. This lens reduces transmission of short–wavelength light, and it has been suggested that vision will be impaired under scotopic conditions. We recently demonstrated that a trial lens had no effect on hue discrimination and no significant effect on dark–adapted sensitivity in healthy young individuals (1). Here we compare hue discrimination and dark–adapted sensitivity in patients who have had implantation of an AcrySof Natural "yellow" IOL in one eye and a UV light absorbing IOL (colorless) in the fellow eye.
Nine subjects, ranging in age from 16–74 years with a "yellow" IOL in one eye and a UV IOL in the fellow eye, visual acuity of 20/40 or better, were tested monocularly following an NEI questionnaire (VFQ–25). A counter–balanced design was used. Hue discrimination was measured with the FM 100–hue test under standard illuminant C conditions. Following pupil dilation and 40 minutes of dark adaptation, rod–mediated thresholds to 440, 500, 650 nm and "white" light stimuli were then measured in each eye in 23 locations using a modified Humphrey perimeter.
There were no significant differences in FM 100–hue error scores or axes for eyes with the "yellow" tinted IOLs compared to those for eyes with the colorless UV IOLs. There were also no significant differences in dark–adapted sensitivities to 440, 500, 650 nm or white light stimuli.
The "yellow" tinted lens does not adversely affect hue discrimination or dark–adapted sensitivities to 440, 500 and 650 nm and "white" light. These results for a group of patients together with previous data obtained on healthy young individuals (1) suggest that visual performance in scotopic conditions and color perception will not be impaired following implantation of a "yellow" tinted IOL. 1.Baker et al ARVO (2005)
