A modified bicanalicular intubation procedure to repair canalicular lacerations using silicone tubes
1State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China.
Purpose:
To explore a modified technique for silicone intubation for the repair of canalicular lacerations.
Methods:
The surgery was performed on 35 eyes in 35 adult patients from October 2007 to September 2009. Using a modified soft probe, silicone tubes were inserted through the lacrimal punctum and left in the bicanaliculi for 3-10 months.
Results:
The surgery was performed successfully in all cases. The tubes were removed after 3-10 months (mean 5.3±1.8 months). The mean follow-up time after tube removal was 13.8 months (range, 6-22 months). Lower punctum splitting occurred in one case (2.86%) after the surgery. No other complications associated with the silicone tubes occurred. All the tubes were removed successfully without any difficulty. No iatrogenic injuries occurred during tube removal.
Conclusions:
The modified bicanalicular intubation procedure described here is an effective and atraumatic procedure for the management of canalicular lacerations in adults, and it is associated with fewer complications than the traditional sutures of canalicular lacerations.
