By means of a new optical device developed by Reiner, an "optical implantation" of 6 different bi- and multifocal intraocular lenses (MIOLs) was performed in 20 young healthy subjects, and results were compared with those of a monofocal reference IOL. The following parameters were investigated: distance and near visual acuity, depth of focus and contrast sensitivity. The median of distance visual acuity was 1.0 in all IOLs with the exception of a 7-zone refractive MIOL (0.75). Near acuity without near addition was 1.0 in all MIOL models; through focus curves of all MIOLs showed an increase in depth of focus with a typical two peak course. Contrast sensitivity at high contrasts was reduced for the 7-zone-model, but contrast sensitivity at low contrasts was significantly reduced for all MIOLs, except the 2- and 3-zone refractive models.
借助赖纳研发的一种新型光学装置，对20名年轻健康受试者进行了6种不同双焦点和多焦点人工晶状体（MIOL）的“光学植入”，并将结果与单焦点对照人工晶状体的结果进行比较。研究了以下参数：远视力和近视力、焦深和对比敏感度。除了一种7区折射式MIOL（视力为0.75）外，所有人工晶状体的远视力中位数均为1.0。所有MIOL模型在无近附加镜时的近视力均为1.0；所有MIOL的通过焦点曲线均显示焦深增加，呈现典型的双峰曲线。7区模型在高对比度下的对比敏感度降低，但除2区和3区折射模型外，所有MIOL在低对比度下的对比敏感度均显著降低。
