Purpose: The aim is to analyze the influence of the location of lacrimal canalicular laceration over the eventual anatomical and functional success after surgery. Methods: Retrospective, observational study of proximal canalicular laceration (PCL) and distal canalicular laceration (DCL) repairs by a single surgeon (MS). The distance between lacrimal punctum and the lateral canalicular lacerated end was defined as proximal (<6 mm) and distal (≥6 mm). The operation theater setup, microscopic magnified view, local adrenaline, and pigtail probe were used to locate the medial canalicular lacerated end. All patients underwent lacrimal stenting and the stents were removed after 3 months (12th week visit). After stent removal, a fluorescein dye disappearance test and lacrimal irrigation were performed to assess the anatomical and functional success of the operation. Results: Of 36 canalicular lacerations, 30 (83.33%) were monocanalicular lacerations which were repaired using monocanalicular stents. Of 6 (16.67%) bicanalicular lacerations, three were repaired using bicanalicular stents while in the remaining three, one monocanalicular stent was placed in each lacerated canaliculi. The medial cut end was identified by magnified visualization in 27 (75%), with adjunctive local adrenaline in four (11.11%) and pigtail probe in five (13.89%) patients. The mean post stent removal follow-up was 44 weeks. The DCL (n = 24, 66.67%) showed better functional and complete success as compared to PCL (75% vs. 33.33%, P = 0.03). Eight (22.22%) had spontaneous stent extrusion, two (5.56%) had loop prolapse, four (11.11%) had punctum granuloma, and three (8.33%) had medial canthus dystopia. Conclusion: The location of canalicular laceration may help to prognosticate the functional and qualified success rate. We experienced better-qualified success in the distal canalicular laceration group.
