We sought to document the completion rate of primary posterior continuous curvilinear capsulorhexis during congenital cataract surgery and determine the incidence of disruption of vitreous face during this procedure.
One hundred six consecutive eyes of patients undergoing posterior continuous curvilinear capsulorhexis (PCCC) during congenital cataract surgery were evaluated prospectively for completion of PCCC and disruption of vitreous face. PCCC was performed under high-viscosity sodium hyaluronate (Healon GV 1.4%) initiated with 26 g of cystotome and later completed with Kraff-Uttrata forceps by frequent grasping and regrasping of the flap. Completion of PCCC and disruption of vitreous face during the procedure was noted. Even in cases of disrupted vitreous face, PCCC was performed and completed with forceps and, later, disruption of vitreous face was managed with 2-port automated limbal anterior vitrectomy. The size of PCCC was measured. An Alcon AcrySof SA30AL was implanted in-the-bag if the PCCC was 4 mm or smaller and in the sulcus when the PCCC was larger than 4 mm.
The mean age of the 106 pediatric patients was 17 +/- 26 months (median, 6 months; range, 1 month to 8 years). PCCC was completed in all the eyes. Disruption of vitreous face during PCCC was noted in 5 of 106 (4.7%) eyes. The mean size of PCCC was 3.6 +/- 0.7 mm. A total of 98 (92.5%) had in-the-bag, and 8 (7.5%) eyes had sulcus implantation of IOL.
PCCC was completed in all eyes with minimal disruption of vitreous face in a well-controlled manner under high-viscosity viscoelastics.
我们试图记录先天性白内障手术中原发性后连续环形撕囊的完成率，并确定该手术过程中玻璃体前界膜破裂的发生率。
对106例在先天性白内障手术中接受后连续环形撕囊（PCCC）的患者的连续106只眼进行前瞻性评估，以观察PCCC的完成情况和玻璃体前界膜的破裂情况。PCCC在高粘度透明质酸钠（Healon GV 1.4%）下进行，先用26G截囊针开始，随后用克拉夫-乌特拉塔镊通过频繁抓取和重新抓取瓣片来完成。记录手术过程中PCCC的完成情况和玻璃体前界膜的破裂情况。即使在玻璃体前界膜破裂的情况下，也用镊子完成PCCC，随后用2端口自动角膜缘前玻璃体切除术处理玻璃体前界膜破裂。测量PCCC的大小。如果PCCC为4mm或更小，则将爱尔康AcrySof SA30AL人工晶状体植入囊袋内；如果PCCC大于4mm，则植入睫状沟。
106例儿科患者的平均年龄为17±26个月（中位数为6个月；范围为1个月至8岁）。所有眼均完成了PCCC。106只眼中有5只（4.7%）在PCCC过程中出现玻璃体前界膜破裂。PCCC的平均大小为3.6±0.7mm。共有98只眼（92.5%）植入了囊袋内人工晶状体，8只眼（7.5%）植入了睫状沟人工晶状体。
在高粘度粘弹性物质的良好控制下，所有眼均完成了PCCC，玻璃体前界膜的破坏最小。
