To compare the impairment in visual function caused by glare with 2 acrylic intraocular lenses (IOLs) with different modified optic edges.
Hayashi Eye Hospital, Fukuoka, Japan.
Fifty-four patients had implantation of an IOL with a textured edge (Alcon MA60AC) in 1 eye and an IOL with a round-anterior, sloped-sided edge (AMO AR40e) in the opposite eye. Visual acuity was measured at 5 contrast visual targets (100%, 25%, 10%, 5%, and 2.5%) (contrast visual acuity) under photopic and mesopic conditions with and without a glare source approximately 1 month after surgery using the Contrast Sensitivity Accurate Tester (Menicon CAT-2000).
The mean mesopic contrast visual acuity at moderate- to low-contrast visual targets was significantly worse in the presence of a glare source in both groups, whereas photopic contrast visual acuity did not change significantly. There were no significant differences between the 2 groups in the mean visual acuity or in photopic or mesopic lighting contrast visual acuity with and without a glare source. Furthermore, there was no significant difference in loss of contrast visual acuity in the presence of glare.
Mesopic contrast sensitivity with both acrylic IOLs was impaired significantly in the presence of glare, but the impairment of contrast sensitivity from glare was approximately the same between eyes with a textured-edge IOL and eyes with a round-anterior, sloped-sided edge IOL.
比较两种具有不同改良光学边缘的丙烯酸人工晶状体（IOL）所引起的眩光导致的视觉功能损害。
日本福冈市林眼科医院。
54例患者一只眼植入带纹理边缘的IOL（爱尔康MA60AC），另一只眼植入圆形前表面、倾斜侧面边缘的IOL（眼力健AR40e）。术后约1个月，使用对比敏感度精确测试仪（目立康CAT - 2000），在明视和微光条件下，分别在有和没有眩光光源的情况下，对5个对比度视觉目标（100%、25%、10%、5%和2.5%）测量视力（对比视力）。
在有眩光光源的情况下，两组中低对比度视觉目标的平均微光对比视力均显著变差，而明视对比视力无显著变化。两组在平均视力、有无眩光光源时的明视或微光照明对比视力方面均无显著差异。此外，有眩光时对比视力的损失也无显著差异。
在有眩光的情况下，两种丙烯酸IOL的微光对比敏感度均显著受损，但带纹理边缘IOL的眼睛和圆形前表面、倾斜侧面边缘IOL的眼睛因眩光导致的对比敏感度损害大致相同。
