Evaluation of color perception in cataract patients bilateral implanted with presbyopia-correcting intraocular lenses

To evaluates postoperative color perception in cataract patients implanted with various yellow-tinted intraocular lenses (Y-IOL) and clear intraocular lenses (C-IOL), including extended depth of focus (EDOF) and trifocal lenses, using the Farnsworth-Munsell 100 Hue test. An observational clinical study was conducted on patients undergoing cataract surgery with bilateral implantation of either Y-IOL or C-IOL at Guangzhou Aier Eye Hospital. Patients were categorized into Y-IOL and C-IOL groups based on lens tint and further subcategorized by design (EDOF vs. trifocal, Y-trifocal vs. C-trifocal). The FM-100 Hue test assessed total error score root mean square (TES RMS), angle, C-Index, S-Index, and total test duration three months postoperatively. Statistical analyses included Kruskal-Wallis, ANOVA, and Mann-Whitney U tests. Among 54 patients (108 eyes), no significant differences in TES, angle, C-Index, S-Index, or test duration were observed between Y-IOL and C-IOL groups or between EDOF and trifocal IOL groups (all P > 0.05). However, a significant difference in the S-Index was noted between the Y-trifocal and C-trifocal IOL subgroups (P < 0.05), indicating differing color axis scatter tendencies. The implantation of blue-light filtering IOLs does not significantly affect color perception when compared to clear IOLs. The design differences between presbyopia-correcting IOLs, such as extended depth of focus and trifocal IOLs, also had minimal impact on patients' postoperative color vision, except for a notable difference in scatter index between two trifocal IOLs.
