AIM: To investigate the clinical effect of canaliculotomy joint novel R-S lacrimal tube implantation under lacrimal endoscope for canaliculitis.METHODS: Thirty-one patients(thirty-two eyes)diagnosed as canaliculitis were investigated from July 2016 to September 2019 in our department. All patients have treated with canaliculotomy joint lacrimal tube implantation under lacrimal endoscope. The patients were randomly divided into two groups. Group A was treated with novel R-S lacrimal tube for 15 cases 15 eyes, and group B was treated with annular silicone tube. They were removed the lacrimal tube after 2-3mo, and followed postoperatively for at least 1a. The treatment results were comparatively analyzed.RESULTS: The effective rate was 93% in group A and 94% in group B(P>0.05). The mean time of lacrimal tube implantation of group A was 2.27±1.335min, and group B was 5.29±1.404min. The total rate of complications was 7% in group A and 47% in group B. The rate of foreign body sensation in nasal cavity was 7% in group A and 41% in group B. The rate of increased nasal secretions was 0 in group A and 29% in group B. The difference of the mean time of lacrimal tube implantation, the rate of complications, the rate of foreign body sensation in nasal cavity and the rate of increased nasal secretions between two groups was statistically significant(P

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(PCONCLUSION: 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.
