方法：选择2013-10/2015-10在我院接受诊治的39例39眼泪小点膜闭患者，应用小梁咬切器行泪小点咬切成形联合新型RS泪道再通管置入术，术后3mo后取出RS泪道再通管，拔管后随诊6mo。比较术前与拔管后1、3、6mo的荧光素染色消失试验评级，拔管后6mo评定该术式的疗效。

结果：荧光素染色消失试验：拔管后1、3、6mo的荧光素染色消失试验评级均低于术前，差异具有统计学意义(P<0.05)。截至末次随访，治愈35眼(90%)，好转4眼(10%)，未见复发病例，有效率100%。无术中及术后严重并发症发生。

结论：小梁咬切器咬切泪小点成形联合RS泪道再通管置入术是一种治疗泪小点膜闭的安全、有效的新方法，操作简便，成功率高。

METHODS: Totally 39 patients(39 eyes)with punctual stenosis were selected from October 2013 to October 2015 in the Second People's Hospital of Foshan. All patients underwent punctoplasty by using trabeculectomy punch combined with a novel RS tube. These tubes were removed at 3mo after operation. A follow-up of 6mo was taken for final analysis. The fluorescein dye disappearance test score was recorded before the operation and at 1,3 and 6mo after the extubation. The curative effect of the operation at 6mo after the extubation was assess.

RESULTS: Fluorescein dye disappearance test: the scores at 1,3 and 6mo after the extubation all decreased compared with the preoperative ones. The difference was statistically significant(P<0.05). At the last following up, 35 eyes(90%)were cured completely, 4 eyes(10%)were improved significantly, no patients recurred. Effective rate was 100%. No serious intraoperative and postoperative complications happened.

CONCLUSION: Punctoplasty by using trabeculectomy punch combined with novel RS tubes is a safe and effective method for the punctul stenosis, which is easy to perform, with high success rate.
