Trabeculectomy punch combined with a novel RS tube for the treatment of punctal stenosis

AIM: To investigate the feasibility and clinical effect of punctoplasty by using trabeculectomy punch combined with a novel RS tube for the treatment of punctal stenosis.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
