Abstract

Purpose: : To investigate photopic and mesopic color discrimination in patients with different intraocular lenses (IOLs).

Methods: : Forty-three cataract patients implanted with different IOLs, including photochromic blue-light filtering IOL (n=15, the photochromic group), yellow-tinted blue-light filtering IOL (n=13, the yellow group) and UV-only absorbing IOL (n=15, the clear group), were enrolled three months after cataract surgery. The best corrected visual acuity (BCVA) under photopic condition (1000 lux) and mesopic condition (40 lux) was measured with Snellen chart. Color discrimination under photopic (1000 lux) and mesopic (40 lux) condition was evaluated with the Farnsworth-Munsell (FM) 100-Hue test. The 85 colore caps around the hue circuit of FM 100-Hue were subdivided into ten color brands according to the FM 100-Hue scoring software and discrimination in the ten brands was analyzed respectively. Subjective visual quality was assessed by the questionnaire of NEI VFQ-25.

Results: : In the three groups, BCVA under photopic and mesopic condition was comparable. There was no statistical difference in total error score in FM 100-Hue under photopic and mesopic condition. Under photopic condition, partial error scores in the ten brands of FM 100-Hue hue circuit revealed no statistical differences. Under mesopic condition, partial error scores in brands of green to blue-green (G-BG, color caps 36-46) and blue-green to blue (BG-B, color caps 46-54) showed statistical differences (P=0.005 and P=0.030). In the G-BG color brand, it was statistically different when the yellow group was compared to the clear group or the photochromic group (P=0.015 and P=0.002). In the BG-B color brand, statistical difference was only detected between the clear group and the yellow group (P=0.017). The average score of NEI VFQ-25 and scores of its subheadings showed no statistically differences.

Conclusions: : Filtering blue-light under mesopic condition could modify delicate color discrimination in green to blue color brand (color caps 36-54 in FM 100-Hue) in postoperative cataract patients. However, the subtle modification would not evoke disturbance to overall color discrimination or subjective discomforts.
