A randomised controlled trial in progress for more than five years, with no loss to follow-up (except death), assessed 333 eyes treated by three methods of cataract surgery. They were (A) intracapsular extraction and contact lens usage, (B) intracapsular extraction and implantation of an iris supported lens (Federov I), and (C) extracapsular extraction and implantation of an iridocapsular lens (Binkhorst 2-loop). The purpose of the paper is to report interim visual results, complications, and corneal endothelial cell loss. More eyes in groups A (contact lens) and C (extracapsular + implant) achieved better visual acuity than in group B (intracapsular + Federov lens), which also had more postoperative complications. Both implant groups lost more endothelial cells than the non-implant group, which did not differ significantly from group B before one year.
一项进行了五年多的随机对照试验,无失访(死亡除外),评估了采用三种白内障手术方法治疗的333只眼睛。它们分别是:(A)囊内摘除术并使用隐形眼镜;(B)囊内摘除术并植入虹膜支撑晶状体(费德罗夫I型);(C)囊外摘除术并植入虹膜囊袋晶状体(宾克霍斯特双袢型)。本文旨在报告中期视力结果、并发症及角膜内皮细胞损失情况。A组(隐形眼镜)和C组(囊外摘除术+植入)中视力较好的眼睛比B组(囊内摘除术+费德罗夫晶状体)更多,且B组术后并发症也更多。两个植入组损失的内皮细胞均比非植入组多,非植入组在一年前与B组无显著差异。
