To evaluate photopic and mesopic color discrimination in patients with different types of light-filtering intraocular lenses (IOLs).
Peking University Third Hospital, Peking University Eye Center, Beijing, China.
Cataract patients with different types of IOLs were enrolled 3 months postoperatively. Overall and partial color discrimination under photopic (1000 lux) and mesopic (40 lux) conditions were evaluated with the Farnsworth-Munsell (FM) 100-hue test. Corrected distance visual acuity (CDVA) was tested under both conditions. Subjective visual quality was assessed with the 25-item National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25).
The study evaluated 43 patients with a blue light-filtering IOL (15 photochromic, 13 yellow tinted) or an IOL filtering ultraviolet light only (n = 15). The difference in the FM 100-hue total error scores under photopic or mesopic conditions was not statistically significant between groups. There were no statistically significant differences in partial error scores in the 10 bands of the FM 100-hue color circle under photopic conditions. Under mesopic condition, there were statistically significant differences in partial error scores in the green to blue-green band (color caps 36 to 46) and the blue-green to blue band (color caps 46 to 54) (P = .005 and P = .030, respectively). There were no statistically significant differences in mean overall or subheading NEI VFQ-25 scores.
Filtering blue lights under mesopic conditions seemed to modify color discrimination in the green-to-blue bands postoperatively. The modification did not disturb overall color discrimination or cause subjective discomfort.
评估不同类型光致变色人工晶状体（IOL）患者的明适应和中间适应色觉辨别能力。
中国北京，北京大学第三医院，北京大学眼科中心。
术后 3 个月招募不同类型 IOL 的白内障患者。用 Farnsworth-Munsell （FM）100 色调测试评估明适应（1000 勒克斯）和中间适应（40 勒克斯）条件下的整体和部分色觉辨别能力。在两种条件下测试矫正远视力（CDVA）。使用 25 项国家眼科研究所视觉功能问卷（NEI VFQ-25）评估主观视觉质量。
本研究评估了 43 名具有蓝光滤光 IOL（15 名光致变色，13 名黄色着色）或仅滤除紫外线 IOL 的患者（n = 15）。在明适应或中间适应条件下，FM 100 色调总误差评分的组间差异无统计学意义。在明适应条件下，FM 100 色调色圈的 10 个波段的部分误差评分无统计学差异。在中间适应条件下，绿色到蓝绿色波段（色标 36 至 46）和蓝绿色到蓝色波段（色标 46 至 54）的部分误差评分有统计学差异（P =.005 和 P =.030）。整体或分项 NEI VFQ-25 评分无统计学差异。
在中间适应条件下过滤蓝光似乎会改变术后绿色到蓝色波段的色觉辨别能力。这种改变不会干扰整体色觉辨别能力或引起主观不适。
