AIM:To disscus the clinical effect of the silicone tube implantation under the guidance of memory wire in the treatment of lacrimal canaliculus.

METHODS: One hundred and fifteen cases(115 eyes )of traumatic canalicular laceration were treated by canaliculoplasty from September 2012 to June 2014. Finding the end of lacrimal canaliculus under microscope, guided by memory wire which was probed in lacrimal passage to the nasal cavity, intubating double-passage silicone tube as a support and end-to-end anastomosis. The condition of epiphora and irrigation of lacrimal passage were observed after extubation.

RESULTS: All 115 cases were experienced successful operation. All patients were followed up for 6mo～1a(mean 9.3mo)after extubation. Lacrimal passage was unobstructed in 96 cases 96 eyes(83.5%), stricture in 13 cases 13 eyes(11.3%), and blocked in 6 cases 6 eyes(5.2%).

CONCLUSION:Double-passage silicone tube guided by memory wire may be an optional technique in the treatment of traumatic lacrimal duct laceration, which is a feasible, minimally-invasive, safe and effective method.
