PURPOSE
To determine the characteristics of eyes with late in-the-bag dislocation of an intraocular lens (IOL) after pars plana vitrectomy (PPV).
METHODS
Fourteen eyes of 14 patients with a dislocated IOL after PPV were studied retrospectively. The data collected from the medical charts included the age, sex, history of eye diseases, axial length, and interval from PPV to time of IOL dislocation. The surgical procedures used during the PPV were also recorded.
RESULTS
Seven eyes had undergone PPV for rhegmatogenous retinal detachment; 6 eyes, for proliferative diabetic retinopathy; and 1 eye, for retinal vein occlusion. The average interval between the PPV and the diagnosis of the dislocated IOL was 6.2 years (range 2.3-10.1 years). In all eyes, the peripheral vitreous was thoroughly removed with scleral depression during the PPV.
CONCLUSIONS
The IOL dislocation was most likely caused by damage to the zonular fibers by the peripheral vitrectomy with scleral depression.
目的
确定玻璃体切割术后人工晶状体（IOL）囊袋内晚期脱位眼的特征。
方法
回顾性研究14例玻璃体切割术后人工晶状体脱位患者的14只眼。从病历中收集的数据包括年龄、性别、眼部疾病史、眼轴长度以及玻璃体切割术至人工晶状体脱位的时间间隔。还记录了玻璃体切割术中使用的手术步骤。
结果
7只眼因孔源性视网膜脱离接受了玻璃体切割术；6只眼因增殖性糖尿病视网膜病变；1只眼因视网膜静脉阻塞。玻璃体切割术至诊断人工晶状体脱位的平均间隔时间为6.2年（范围2.3 - 10.1年）。所有眼中，在玻璃体切割术中通过巩膜压迫彻底清除了周边玻璃体。
结论
人工晶状体脱位很可能是由于巩膜压迫下的周边玻璃体切除术对悬韧带纤维造成损伤所致。
