A basic goal associated with the manufacture of intraocular lenses (IOLs) is that they not be vision limiting. Manufacturers must therefore test IOL resolution against some minimum requirement. Currently, American National Standards Institute voluntary standard Z80.7-1984 addresses IOL optical requirements. One criterion of this standard is a minimum resolving power of 100 line-pairs-per-millimeter. This report presents some results of lens testing that suggest this standard is inadequate because it may not control the performance of a large enough fraction of the optic aperture.
与人工晶状体（IOL）制造相关的一个基本目标是它们不会限制视力。因此，制造商必须根据一些最低要求测试IOL的分辨率。目前，美国国家标准学会的自愿标准Z80.7 - 1984涉及IOL的光学要求。该标准的一个标准是每毫米100对线对的最小分辨能力。本报告展示了一些晶状体测试结果，这些结果表明该标准不充分，因为它可能无法控制足够大部分的光学孔径的性能。
