A case of late spontaneous dislocation of the lens capsular bag (CB) with foldable acrylic intraocular lens (IOL) and endocapsular tension ring (CTR) and its surgical management is reported in a 52-year-old man. The dislocation occurred 2 years 3 months after phacoemulsification cataract surgery in which a CTR was used for zonular instability. A 3-port pars plana vitrectomy was performed. Because it was not possible to grasp the IOL-CTR-CB complex, perfluorocarbon liquid was used to attempt to float it up. This was unsuccessful, so a scleral indenter was used to apply external pressure on the sclera to tilt the IOL-CTR-CB complex into a position where it could be grasped with a forceps and removed through a corneal section. A scleral-fixated IOL was placed, and the patient achieved a best corrected visual acuity of 6/9. The procedure was safe and effective without intraocular complications.
本文报道了一例52岁男性患者，其折叠式丙烯酸人工晶状体（IOL）和囊内张力环（CTR）所在的晶状体囊袋（CB）发生晚期自发性脱位及其手术治疗情况。脱位发生在白内障超声乳化手术后2年3个月，此次手术中因悬韧带不稳定使用了CTR。进行了三通道平坦部玻璃体切除术。由于无法夹住IOL-CTR-CB复合体，遂使用全氟碳液体试图使其上浮，但未成功，于是使用巩膜压陷器对巩膜施加外部压力，将IOL-CTR-CB复合体倾斜至能用镊子夹住并通过角膜切口取出的位置。植入了巩膜固定IOL，患者最佳矫正视力达到了6/9。该手术安全有效，未出现眼内并发症。
