To examine color perception in patients receiving bilateral implantation of an ultraviolet (UV) and blue-light filtering intraocular lens (IOL) (AcrySof Natural SN60AT, Alcon Laboratories Inc.) or a UV-only filtering IOL (AcrySof SA60AT) and to compare the results with those in a phakic group.


Cincinnati, Ohio, USA.


In this prospective study, age-matched subjects who passed the Ishihara test and had visual acuities of 20/25 or better were recruited. There were 2 pseudophakic groups (bilateral SN60AT or SA60AT IOLs) and 1 phakic group. The Farnsworth-Munsell (FM) 100-hue test was administered to each subject twice under different conditions. The phakic and AcrySof Natural SN60AT groups were tested under photopic and mesopic conditions. The SA60AT subjects were further divided into subgroups (with and without yellow clip-on lenses) and tested under photopic and mesopic conditions.


A 1-way analysis of variance (ANOVA) of the square-root-transformed total error score showed no statistical differences (P = .637) between the treatment groups. Similarly, a 1-way ANOVA of the red-green error score (P = .729) and blue-yellow error score (P = .484) indicated no statistically significant differences between the treatment groups. The ANOVA results of the FM 100-hue test under mesopic conditions showed that the total error score in the AcrySof Natural IOL group was significantly lower (P = .046) than in the phakic group. There were no between-group differences in error scores under mesopic conditions.


The FM 100-hue testing showed no difference in color perception between subjects with AcrySof Natural IOLs and those in an age-matched phakic control group or in those with a UV-only filtering AcrySof IOL with or without yellow clip-on lenses.
