20G silicone rod as monocanalicular stent in repair of canalicular lacerations: Experience from a tertiary eye care centre

Abstract

To evaluate the outcome of 20G silicone rod as monocanalicular stent in canalicular lacerations. Retrospective case series involving patients between July 2006 and June 2010. Fourteen canalicular repairs in 12 consecutive patients were done in the study period. Eleven were male and mean age was 30.5 years. A single canaliculus was involved in 10 patients and associated injury to the globe was noted in 3 patients. The median lag time between injury and repair was 3 (range 1-9) days. The mean duration of stenting was 6.9 (SD 3.2) weeks. Spontaneous extrusion of monocanalicular stent occurred in 3 patients. Patency on syringing was noted in 10 (70%) canaliculi over a median follow up of 7 (range 2-17) months. 20G silicone rod may be used as an effective and economical alternative in canalicular lacration repairs.
