PURPOSE To compare the rate of posterior synechiae of the iris (PSI) occurrence after phacovitrectomy between a group with lens-in-the-bag (LIB) implantation, that is, implantation in the capsular bag, and a group with bag-in-the-lens (BIL) implantation. SETTING CHU de Caen, Department of Ophthalmology, Caen, France. DESIGN Comparative retrospective study. METHODS One hundred consecutive cases of phacovitrectomies conducted between May 2013 and July 2016 were included. A retrospective analysis of the occurrence rate of PSI in the LIB group and in the BIL group was performed, using multivariate analysis including multiple risk factors such as preoperative synechiae, proliferative diabetic retinopathy, use of 20-gauge vitrectomy, use of gas or silicone tamponade, and use of endophotocoagulation. RESULTS One hundred eyes of 92 patients were included in this study (55 eyes in the LIB group and 45 in the BIL group). The occurrence of PSI was significantly lower in the BIL group with 1 case (2%) versus 22 cases (40%) in the LIB group (P < .001). Among the risk factors studied, preoperative synechiae and the use of retinal endophotocoagulation were almost significantly associated with the occurrence of PSI (P = .068 and P = .087, respectively). In the LIB group, these PSI led to 1 case of acute elevation of intraocular pressure by pupillary seclusion and the use of laser iridotomy in 8 cases. CONCLUSION The use of BIL rather than LIB implantation in phacovitrectomy practically eliminates PSI.

晶状体袋植入术有助于避免白内障摘除术后虹膜后粘连。

目的比较袋装晶状体袋(LIB)植入组(即囊袋中植入)和袋中囊袋植入组在白内障摘除术后虹膜后粘连(PSI)发生率镜头(BIL)植入。SETTING CHU de Caen,法国卡昂眼科。设计比较回顾性研究。方法纳入2013年5月至2016年7月连续进行的100例白内障患者。回顾性分析LIB组和BIL组中PSI的发生率,采用多因素分析,包括多种危险因素,如术前粘连,增生性糖尿病性视网膜病变,使用20规格玻璃体切除术,使用气体或硅脂填塞,并使用内光凝。结果本研究纳入了92例患者的一百只眼(LIB组为55眼,BIL组为45眼)。BIL组中PSI的发生率显着降低,其中1例(2%),而LIB组为22例(40%)(P <.001)。在研究的危险因素中,术前粘连和视网膜内光凝的使用与PSI的发生几乎密切相关(分别为P = .068和P = .087)。在LIB组中,这些PSI导致1例因瞳孔隐匿而急性眼压升高,并使用激光虹膜切开术8例。结论在晶状体玻璃体切除术中使用BIL而非LIB植入实际上消除了PSI。BIL组中PSI的发生率显着降低,其中1例(2%),而LIB组为22例(40%)(P <.001)。在研究的危险因素中,术前粘连和视网膜内光凝的使用与PSI的发生几乎密切相关(分别为P = .068和P = .087)。在LIB组中,这些PSI导致1例因瞳孔隐匿而急性眼压升高,并使用激光虹膜切开术8例。结论在晶状体玻璃体切除术中使用BIL而非LIB植入实际上消除了PSI。BIL组中PSI的发生率显着降低,其中1例(2%),而LIB组为22例(40%)(P <.001)。在研究的危险因素中,术前粘连和视网膜内光凝的使用与PSI的发生几乎密切相关(分别为P = .068和P = .087)。在LIB组中,这些PSI导致1例因瞳孔隐匿而急性眼压升高,并使用激光虹膜切开术8例。结论在晶状体玻璃体切除术中使用BIL而非LIB植入实际上消除了PSI。在LIB组中,这些PSI导致1例因瞳孔隐匿而急性眼压升高,并使用激光虹膜切开术8例。结论在晶状体玻璃体切除术中使用BIL而非LIB植入实际上消除了PSI。在LIB组中,这些PSI导致1例因瞳孔隐匿而急性眼压升高,并使用激光虹膜切开术8例。结论在晶状体玻璃体切除术中使用BIL而非LIB植入实际上消除了PSI。
