This report describes a single-piece poly-(methyl methacrylate) posterior chamber lens for implantation through a small capsular opening. It has open circular loops with an eyelet at each loop end. The optic is 6 mm in diameter and the overall diameter of the intraocular lens (IOL) is 11 mm. The lens diameter can be reduced to 7 mm by grasping the eyelets at both open loop ends with a specially designed holding forceps. The IOL is inserted in the capsular bag after circular capsulorhexis or through a linear capsulotomy in the intercapsular technique. This IOL is adaptable to a small capsular opening and maintains the usual shape of the capsular bag, similar to a disc lens.
本报告描述了一种单件式聚甲基丙烯酸甲酯后房型人工晶状体，用于通过小的囊袋开口植入。它有开放的圆形袢，每个袢端有一个小孔。光学部直径为6mm，人工晶状体（IOL）的总直径为11mm。通过用一种特殊设计的夹持镊抓住两个开放袢端的小孔，晶状体直径可减小至7mm。在连续环形撕囊后或采用囊间技术通过线性截囊术将IOL植入囊袋内。这种IOL适用于小的囊袋开口，并能保持囊袋的正常形状，类似于盘状晶状体。
