To evaluate the safety and efficacy of staining the posterior capsule with trypan blue during capsulorhexis in pediatric cataract surgery.
This was a prospective randomized comparative study carried out at Alpha Vision Center, Zagazig, Egypt. This study included 2 groups of children with pediatric cataract randomly allocated to undergo irrigation and aspiration. In the trypan group, which included 11 eyes, trypan blue was used to stain the posterior capsule during posterior capsulorhexis. In the control group, which included 10 eyes, no staining was performed. All surgeries were performed by the same surgeon. The 2 groups were compared for criteria such as completion of capsulorhexis, disruption of vitreous face and in-the-bag intraocular lens implantation.
This study included 21 eyes of 16 patients (age range: 6 months-4 years). A statistically significant difference was observed for the following parameters between the 2 groups: capsulorhexis completion (=0.04), vitreous face disruption (=0.01) and in-the-bag intraocular lens implantation (=0.022).
This study suggests that staining of the posterior capsule during capsulorhexis in pediatric cataract operation gives better results than capsulorhexis without staining. The stain changes the capsule texture making capsulorhexis easier with fewer complications.
评估在儿童白内障手术撕囊过程中用台盼蓝对后囊膜进行染色的安全性和有效性。
这是一项在埃及扎加齐格阿尔法视觉中心进行的前瞻性随机对照研究。本研究纳入2组患有儿童白内障的患儿，随机分配接受冲洗吸出术。在台盼蓝组（11只眼）中，在撕后囊膜时使用台盼蓝对后囊膜进行染色。在对照组（10只眼）中，不进行染色。所有手术均由同一位外科医生进行。比较两组在撕囊完成情况、玻璃体前界膜破裂情况及囊袋内人工晶状体植入情况等标准方面的差异。
本研究纳入16例患者的21只眼（年龄范围：6个月至4岁）。两组之间在以下参数方面观察到统计学上的显著差异：撕囊完成情况（=0.04）、玻璃体前界膜破裂情况（=0.01）及囊袋内人工晶状体植入情况（=0.022）。
本研究表明，儿童白内障手术撕囊过程中对后囊膜进行染色比不染色的撕囊效果更好。染色改变了囊膜质地，使撕囊更容易且并发症更少。
