目的：比较植入蓝光滤过和非黄色人工晶状体 (IOL) 的患者的对比敏感度和色觉。地点：西班牙巴伦西亚 NISA Valencia al Mar 医院屈光手术室。方法：20 名患者的 40 只眼睛参加了蓝光滤过同眼对照研究；白内障手术后，患者的一只眼睛植入了黄色人工晶状体（AcrySof Natural，爱尔康），另一只眼植入了非黄色人工晶状体（AcrySof SA60AT，爱尔康）。术后三个月，使用 CSV 1000-E 远距离对比敏感度表测量单眼对比敏感度功能，并使用 Farnsworth-Munsell 100 Hue 测试进行颜色辨别。 结果：植入蓝光过滤人工晶状体的眼睛与植入非黄色人工晶状体的对侧眼的对比敏感度相似（P>.1）。两种类型的 IOL 均显示正常的对比敏感度值（标准化对数对比敏感度约为 1.0）。两种类型的人工晶状体之间的色觉辨别力没有统计学上的显着差异（P=.56）。结论：使用蓝光过滤人工晶状体更可取，因为它们能够保护视网膜免受紫外线照射，而不会干扰对比敏感度和色觉，从而产生视觉功能的主观损害。
PURPOSE: To compare contrast sensitivity and color vision in patients in whom blue-light filtering and non-yellow-tinted intraocular lenses (IOLs) were implanted.SETTING: Refractive Surgery Unit, Hospital NISA Valencia al Mar, Valencia, Spain.METHODS: Forty eyes of 20 patients were enrolled in a blue-light filtering fellow-eye control study; patients were implanted with a yellow-tinted IOL (AcrySof Natural, Alcon) in 1 eye and a non-yellow-tinted IOL (AcrySof SA60AT, Alcon) in the fellow eye after cataract surgery. Three months postoperatively, monocular contrast sensitivity function was measured with the CSV 1000-E contrast sensitivity chart at distance and the color discrimination with the Farnsworth-Munsell 100 Hue test.RESULTS: Eyes implanted with blue-light filtering IOLs showed similar contrast sensitivity to that in fellow eyes implanted with non-yellow-tinted IOLs (P>.1). Both types of IOLs showed normal contrast sensitivity values (normalized log-contrast sensitivity about 1.0). There were no statistically significant differences in chromatic discrimination between the 2 types of IOLs (P=.56).CONCLUSION: The use of blue-light filtering IOLs is more advisable because they are capable of protecting the retina against ultraviolet light without disturbance of contrast sensitivity and chromatic vision, which produces subjective impairment in visual function.
