To determine whether closing the scleral flap with extra sutures can reduce the risk of overfiltration after trabeculectomy, we divided 339 trabeculectomies into three groups based on the number of scleral flap sutures used in the procedure, and studied the postoperative complications and results. The incidence of shallow or flat anterior chamber was significantly less in eyes that had received seven to nine sutures than in those that had received from two to six. Also, the incidence of cornea-lens touch was significantly less in the eyes with seven to nine sutures (P = .02, Fisher Exact Test). This study suggests that extra scleral flap sutures (in combination with laser suture lysis) is a safe and effective method of significantly reducing the risk of overfiltration after trabeculectomy.
为了确定使用额外缝线关闭巩膜瓣是否能降低小梁切除术后滤过过度的风险，我们根据手术中使用的巩膜瓣缝线数量将339例小梁切除术分为三组，并研究了术后并发症及结果。接受7至9针缝线的眼睛浅前房或无前房的发生率明显低于接受2至6针缝线的眼睛。此外，接受7至9针缝线的眼睛角膜-晶状体接触的发生率也明显更低（P = 0.02，Fisher精确检验）。本研究表明，额外的巩膜瓣缝线（联合激光缝线松解）是一种安全有效的方法，可显著降低小梁切除术后滤过过度的风险。
