We report a rare case of a 46-year-old man presenting with a luxation of a posterior chamber intraocular lens (IOL) with the capsular bag after ocular contusion. Preoperative axial length was 36.58 mm. After trauma, pars plana extraction of the dislocated IOL inside the capsular bag was performed using a forceps. Capsular fibrosis had probably weakened the zonules, which were ruptured by the trauma. This observation confirms the necessity of a large continuous curvilinear capsulotomy and meticulous cleaning of the anterior and posterior capsules to minimize postsurgical fibrosis and capsule contraction.
我们报告了一例罕见病例，一名46岁男性在眼部挫伤后出现后房型人工晶状体（IOL）与囊袋脱位。术前眼轴长度为36.58mm。外伤后，使用镊子经睫状体平坦部取出囊袋内脱位的IOL。囊膜纤维化可能使悬韧带变弱，外伤导致其断裂。该观察结果证实了进行大范围连续环形撕囊以及仔细清理前后囊膜以尽量减少术后纤维化和囊膜收缩的必要性。
