Abstract

The Faulkner holding and folding forceps, the Fine folder, and the Prodigy inserter (PRO-1A) were evaluated to assess their effects on silicone intraocular lenses (IOLS) after the lenses were folded. The IOLs were evaluated before folding and at two and 24 hours after folding for haptic dimension, optic quality, and surface quality. None of the instruments caused a clinically important effect on the IOLs 24 hours after folding. The cross-sectional area required for IOL insertion was calculated for each folder. The Prodigy required the smallest cross-sectional area and the Faulkner the largest when folding a 24 diopter lens. We also describe a protocol that can be used to evaluate new IOL folders.

摘要

对福克纳夹持折叠镊、精细折叠器和神童插入器（PRO-1A）进行了评估，以评估它们在折叠后对硅水凝胶人工晶状体（IOL）的影响。在折叠前以及折叠后2小时和24小时对IOL的襻尺寸、光学质量和表面质量进行评估。折叠后24小时，没有一种器械对IOL产生临床重要影响。计算了每种折叠器折叠IOL所需的横截面积。折叠24屈光度的晶状体时，神童插入器所需的横截面积最小，福克纳夹持折叠镊所需的横截面积最大。我们还描述了一种可用于评估新型IOL折叠器的方案。
