Abstract：
OBJECTIVE: To study the postoperative visual outcomes and surgical complications of anterior/pars plana vitrectomy and concurrent Yamane\'s IOL fixation for crystalline lens dislocation.
METHODS: Fifty-three patients (56 eyes) with crystalline lens subluxation/dislocation were enrolled in this retrospective interventional study. Patients received anterior/pars plana vitrectomy and concurrent Yamane\'s IOL fixation. Main outcome measures were postoperative BCVA and surgical complications. Proportion of spontaneous PVD and preoperative undetected retinal holes/degeneration (PURH/D) were recorded.
RESULTS: Twenty-four eyes were treated with anterior vitrectomy (Group AnV) and 32 eyes with pars plana vitrectomy (Group PPV). Overall incidence of PURH/D was 10.7% (6/56). Spontaneous PVD occurred in 68.8% (24/32) in Group PPV. During six months follow-up, one case of postoperative RRD and one case of choroidal detachment occurred in Group AnV. There was no significant difference between anterior vitrectomy and PPV in the final BCVA and postoperative complications.
CONCLUSIONS: Anterior or pars plana vitrectomy, which are both applicable in YAMANE technique for crystalline lens dislocation, exhibit similar surgical outcomes. Patient\'s age, PVD status and PURH helps to determine the route of vitrectomy. Pediatric patients might be potential candidates for transcorneal vitreolensectomy. For adult, PURH managed with total vitrectomy and intraoperative lase retinopexy might be beneficial to decrease the incidence of postoperative RRD.

摘要：
目的：研究前/平坦部玻璃体切除术及同期Yamane’s人工晶状体内固定治疗晶状体脱位的术后视力结果及手术并发症。
方法：纳入53例（56只眼）晶状体脱位/脱位患者的回顾性介入研究。患者接受前段/平坦部玻璃体切除术和同期Yamane人工晶状体固定术。主要结局指标为术后BCVA和手术并发症。记录自发性PVD的比例和术前未发现的视网膜裂孔/变性（PURH/D）。
结果：24只眼采用前部玻璃体切除术（AnV组），32只眼采用平坦部玻璃体切除术（PPV组）。PURH/D的总发生率为10.7%(6/56)。PPV组自发性PVD发生率为68.8%(24/32)。在六个月的随访中，AnV组术后发生RRD1例,脉络膜脱离1例。前路玻璃体切除术和PPV在最终BCVA和术后并发症方面没有显着差异。
结论：前位或平坦部玻璃体切除术，这两种方法都适用于YAMANE技术的晶状体位错，表现出相似的手术结果。病人的年龄,PVD状态和PURH有助于确定玻璃体切除术的途径。小儿患者可能是经角膜玻璃体切除术的潜在候选人。对于成年人来说，采用全玻璃体切除术和术中Lase视网膜固定术治疗PURH可能有利于降低术后RRD的发生率。
