This study aimed to investigate the efficacy and safety of canalicular laceration repair using a novel bicanalicular silicone tube. Retrospective and consecutive patients who underwent canalicular laceration repair using novel Runshi-RS bicanalicular silicone stents from January 2020 to February 2021 were included. The stent was placed for 3 months, and patients were followed up for more than 3 months after extubation. Demographics, causes of eyelid injuries, placement time and position of stent, and surgical outcomes at follow-up were recorded. Anatomical success was evaluated by diagnostic probing and irrigation of lacrimal passage, while functional success was evaluated by the patient's subjective symptoms of epiphora. This study included 43 patients with canalicular laceration. The median age was 43 years (3–75 years). The average duration of stent implantation was 12.9 weeks, and the follow-up time was 8.8 months. No complications were observed in any patients during operation and follow-up. After extubation, irrigation of the lacrimal passage in 43 eyes showed no obstruction, and the anatomical success rate was 100%. Overall, 39 patients (90.7%) had no subjective symptoms of epiphora. All patients got good cosmetic results. Furthermore, subgroup classification showed deep laceration group (distance from laceration to punctum>5 mm) accounted for 51.2%, and the functional success rate of the deep laceration group was lower than that of the shallow laceration group. Runshi-RS bicanalicular silicone stent achieved good anatomical (100%) as well as functional (90.7%) success and good cosmetic results (100%) in patients with canalicular laceration repair.
