We evaluated contrast sensitivity and glare in 64 pseudophakic eyes. An ultraviolet-absorbing intraocular lens (IOL) was implanted in 32 eyes and a noncyanopsia yellow-tinted IOL was implanted in 32 eyes. The latter lens was designed to effectively absorb light below a wave-length of 500 nm. Contrast sensitivity was measured at a pupil diameter of 3 mm using an artificial pupil. The implanted yellow-tinted IOL showed improved contrast sensitivity in the middle spatial frequencies of 6 and 12 c/deg in photopic and mesopic vision. In addition, the yellow-tinted IOL decreased the effect of central glare on the contrast sensitivity.
我们评估了64只人工晶状体眼的对比敏感度和眩光情况。32只眼植入了紫外线吸收型人工晶状体（IOL），32只眼植入了非蓝视黄染色人工晶状体。后一种晶状体旨在有效吸收波长低于500nm的光。使用人工瞳孔在瞳孔直径为3mm时测量对比敏感度。植入的黄染色人工晶状体在明视觉和中间视觉中6和12c/deg的中间空间频率下显示出对比敏感度提高。此外，黄染色人工晶状体降低了中央眩光对对比敏感度的影响。
