To determine the factors predictive of outcome in canalicular laceration repair at a tertiary eye care centre. A retrospective review of the medical records of all primary canalicular laceration repairs managed at a tertiary eye care centre between the years 2006 and 2014 was done. Thirty-nine patients were included and majority were male (79.5%) with a mean age of 30.05 + 16.2 years (range 2-65). Most (n = 34) had monocanalicular laceration and 5 had bicanalicular laceration. All surgeries were done in the operating room setting. Overall patency by irrigation was seen in 74.4% at a median follow-up of 19.89 weeks (range 21-910). Anatomical outcome was different among the stents and best after Mini-Monoka monocanalicular stent (17/19; 89.5%) followed by bicanalicular annular stents (n = 6; 60%) and 20G Silicone rod (8/14, 57%). The factors predictive of poor outcome were related to the mode of injury [road traffic accidents; Hazard ratio (HR)19.57; p = 0.048] and the type of stent [20G silicone rod (HR 35.7; C.I 3.04 - 419.14; p = 0.004)] by multivariate analysis. Skill of the surgeon was critical as the outcome for fellows-in-training showed a trend towards failure (HR 6.66, p = 0.07). Complications included stent extrusion (n = 28.2%), punctal granuloma (n = 5.1%) and stent exposure (n = 2.5%). The mode of injury - road traffic accidents and type of stent - 20 G silicone rod were risk factors predictive of poorer outcome after canalicular laceration repair. Individual skill of operating surgeon may be a critical factor suggesting a review of training protocols.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
