Two patients had fracture of a flexible, open-loop, anterior chamber intraocular lens (IOL) caused by ocular trauma. Case 1 was a 78-year-old woman with a three-point-fixation IOL. The two portions of the fractured lens were removed from the anterior chamber. Visual acuity at 10 months postoperatively was hand motion as a result of corneal decompensation. Case 2 was a 36-year-old man with a four-point-fixation IOL that broke and dislocated into the vitreous. A pars plana vitrectomy was performed; the two lens portions were removed and exchanged with a sutured posterior chamber lens. Best corrected visual acuity 4 months postoperatively was 20/20. In both cases, the lens fracture took place at the loop-optic junction and with minimal visible damage to the eye structures.
两名患者因眼外伤导致可折叠、开环式前房型人工晶状体（IOL）发生断裂。病例1为一名78岁女性，植入的是三点固定IOL。断裂的晶状体两部分从前房取出。术后10个月时，由于角膜失代偿，视力仅为手动。病例2为一名36岁男性，植入的是四点固定IOL，晶状体发生断裂并脱位至玻璃体。进行了经睫状体平坦部玻璃体切除术；取出晶状体两部分，并用缝合的后房型晶状体进行置换。术后4个月时最佳矫正视力为20/20。在这两个病例中，晶状体均在襻-光学部交界处发生断裂，且眼内结构的可见损伤极小。
