Although implantation of an intraocular lens provides excellent postoperative visual acuity, some factors such as disability glare have attached importance to qualitative evaluation of the visual function of artificial pseudophakia. In order to find out which factor most greatly contributed to glare disability, four types of intraocular lens, convexplano, biconvex anterior more curved, posterior more curved, and equiconvex, were prospectively implanted. The patients were 21 men and 63 women, ranging in age from 39 to 92 years (mean +/- SD = 70.9 +/- 10.1 years). Glare disability, examined by the Titmus Miller-Nadler Glare Tester, was found to be significantly correlated to types of intraocular lens, refractive power of intraocular lens, but not to age of patients or strength of postoperative astigmatism. The lower glare disability index value was found in patients implanted with posteriorly more curved biconvex or equiconvex surface, and within a range of 18.5-22 D compared with those implanted with convex anterior or convex-plano surface, and 22.5 D or more.
尽管人工晶状体植入术后可提供出色的视力，但诸如失能眩光等一些因素已成为人工晶状体眼视觉功能定性评估的重要考量。为了找出对眩光失能影响最大的因素，前瞻性地植入了四种类型的人工晶状体，即凸平型、前表面更弯曲的双凸型、后表面更弯曲的双凸型和等凸型。患者包括21名男性和63名女性，年龄在39至92岁之间（平均±标准差 = 70.9±10.1岁）。通过Titmus Miller-Nadler眩光测试仪检测发现，眩光失能与人工晶状体类型、人工晶状体屈光力显著相关，但与患者年龄或术后散光度数无关。与植入前表面凸起或凸平型人工晶状体（22.5 D及以上）的患者相比，植入后表面更弯曲的双凸型或等凸型人工晶状体（18.5 - 22 D范围内）的患者眩光失能指数值更低。
