The Worst-Fechner Biconcave Lens for the correction of myopia in phakic eyes is fixated to the anterior iris. Of the 125 eyes implanted between November 1986 and November 1990, 109 eyes ("core group") had a follow-up period of at least 12 months (mean, 25.0; range, 13 to 51). Sixty-eight of these eyes were reexamined at Giessen University Eye Clinic by an independent investigator using a laser flare cell meter; 23 of the eyes also were examined by iris fluorescence angiography. Seventy-five of the 109 eyes (68.8%) were corrected within 1.00 diopters of the desired refraction, and only 10 eyes (9.2%) deviated more than 2.00 D from the calculated correction. The anatomical results were characterized by good fixation, absence of glaucoma, inflammation, and leak from iris vessels. However, the corneal endothelium was damaged in five eyes by surgical trauma, three resulting in corneal edema. In addition, in five eyes the endothelial density decreased during the follow-up period despite an uncomplicated operation, resulting in corneal edema in one eye. These eyes may have had anterior chambers that were too shallow.
用于矫正有晶状体眼近视的最差 - 费希纳双凹透镜固定于前房虹膜。在1986年11月至1990年11月间植入的125只眼中，109只眼（“核心组”）随访期至少12个月（平均25.0个月；范围13至51个月）。其中68只眼由一位独立研究者在吉森大学眼科诊所使用激光散射细胞仪进行复查；23只眼还接受了虹膜荧光血管造影检查。109只眼中有75只（68.8%）矫正后的屈光度在预期屈光度的1.00屈光度范围内，只有10只眼（9.2%）与计算出的矫正值偏差超过2.00 D。解剖学结果的特征为固定良好、无青光眼、炎症以及虹膜血管渗漏。然而，有5只眼因手术创伤导致角膜内皮受损，其中3只引发角膜水肿。此外，有5只眼尽管手术过程顺利，但在随访期间内皮细胞密度下降，导致1只眼角膜水肿。这些眼的前房可能过浅。
