Abstract

Purpose: This study aimed to evaluate the clinical efficacy of canalicular laceration repair using monocanalicular intubation with Monoka tubes. Methods: A total of 46 patients with 47 lacerated canaliculi were repaired using monocanalicular intubation with Monoka tubes and were continuously followed for 3 months on. All tubes were removed at 3rd month. Epiphora symptoms were evaluated at 1 week, 1 month and 3 months. Fluorescein dye disappearance test, syringing and probing were perfomed at 3 months (tube extrusion). Demographic information, injury locations, associated ocular injuries, complications and outcomes were analysed. Results: Mean patient age was 47 years (range 25–79 years). There were 41 lower canalicular lacerations (89%), 4 upper canalicular lacerations (9%) and 1 both canicular lacerations included. Overall, 37 of 46 cases (80,4%) showed complete improvement in symptoms and exhibited positivity on the dye disappearance test at 3rd month after the procedure, 1 patient (2%) suffered functional failure. In addition, 42 patients (91,3%) gained anatomical success with patency on syringing and probing showed hard stop result. Complications were seen in five cases and included one punctal slit, one lower eyelid slit and two punctal granuloma. Remarkably, there were no case encountered early tube protrusion. Conclusions: Monocanalicular intubation with Monoka tubes leads to successful outcomes without significant complications and offers an alternative to bicanalicular intubation and Mini – monoka tubes in the treatment of monocanalicular lacerations.
