Summary
Purpose
This study aimed to investigate the efficacy and safety of canalicular laceration
repair using a novel bicanalicular silicone tube.
Methods
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.
Results
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.
Conclusion
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.
