Functional outcomes of canalicular laceration repair with self-retaining masterka stent in a tertiary eye care center in France: A retrospective study of 30 patients.

PURPOSE: To evaluate the long-term functional outcomes of canalicular laceration repair using the Masterka® monocanalicular intubation system.

METHODS

this interventional case series included the data from 30 patients who underwent canalicular laceration repair with a 30-mm pushed monocanalicular stent (Masterka®) and suturing of the lacerated canaliculus with 8/0 Vicryl interrupted sutures. Operative details and complications were meticulously noted. Stent removal took place as early as 3 months post-surgery, with functional success defined as the absence of epiphora four years after surgery.

RESULTS

The average age of patients was 28.5±26.3 years, with 20 out of 30 patients (66.6%) being male. Lower canaliculus involvement was noted in 23 patients (76.6%), while the upper canaliculus was affected in 7 patients (23.4%). On average, patients presented for medical attention within approximately one day of sustaining with injuries, and all underwent successful repairs. Notably, functional success was observed in all 30 cases, constituting a 100% success rate. Stent-related complications were encountered in two patients (6.6%). One patient reported stent removal after an average follow-up period of one month, while the other developed a punctal granuloma one-month post-surgery, which regressed following one month of topical steroid treatment.

CONCLUSION

Repairing canalicular lacerations using the self-retaining Masterka® monocanalicular intubation system demonstrated a notable achievement in long-term functional success while presenting minimal complications. To further substantiate these promising results, an interventional study that includes a comparison analysis with other types of intubation methods is warranted.
