Abstract

In a prospective study, intraocular lens power calculations were within +/- 0.50 diopter of the final refraction in 77 of 88 eyes (87.5%) with a biconvex lens and in 41 of 90 eyes (45.5%) with a meniscus lens. The more precise power calculations with the biconvex intraocular lens seemed to be related to the superior optical design of the lens, with its close configuration to a normal crystalline lens.

摘要

在一项前瞻性研究中，88只植入双凸透镜的眼睛中有77只（87.5%）的人工晶状体屈光力计算值与最终验光结果相差在±0.50屈光度以内，而90只植入新月形透镜的眼睛中有41只（45.5%）的计算值在该范围内。双凸人工晶状体更精确的屈光力计算似乎与其优越的光学设计有关，它与正常晶状体的结构相近。
