A survey was sent to all members of the German Society of Ophthalmic Surgeons to evaluate complications that required explantation of foldable intraocular lenses (IOLs).
Data on preoperative visual acuity, foldable IOL design and material, and the reason for explantation were obtained and analysed. We received 185 surveys for 2000 and 2001.
In 2000 and 2001, the most common reasons for IOL explantation were: incorrect lens power (31%) and dislocation (19%) in three-piece acrylic IOLs, incorrect power (31%) and decentration (17%) in monofocal silicone IOLs, and opacification (46%) in hydrophilic IOLs. The most common reasons for the exchange of monofocal IOLs were lens opacification in 2000 and incorrect IOL power in 2001.
Besides the most frequent complications of decentration and incorrect power observed in rigid IOLs,new complications associated with foldable IOLs occurred (e.g., optic opacification and calcification). Accurate calculation of IOL power and further improvements in material and design are still necessary to minimize the rate of explantations.
向德国眼科外科医生协会的所有成员发送调查问卷，以评估需要取出可折叠人工晶状体（IOL）的并发症情况。
获取并分析有关术前视力、可折叠IOL的设计和材料以及取出原因的数据。我们收到了2000年和2001年的185份调查问卷。
在2000年和2001年，IOL取出的最常见原因是：三件式丙烯酸IOL中晶状体屈光度不正确（31%）和脱位（19%），单焦点硅胶IOL中屈光度不正确（31%）和偏心（17%），以及亲水性IOL中混浊（46%）。2000年单焦点IOL更换的最常见原因是晶状体混浊，2001年是IOL屈光度不正确。
除了在硬性IOL中观察到的最常见并发症偏心和屈光度不正确外，与可折叠IOL相关的新并发症也出现了（如光学部混浊和钙化）。仍需要准确计算IOL屈光度，并进一步改进材料和设计，以尽量降低取出率。
