Objective: To study the therapeutic efficiency and effecacy of laser-directing approach on searching for the nasal broken end of lacerated lacrimal canaliculus in anastomosis for canalicular laceration.Methods: Forty-nine patients (49 eyes) suffering from traumatic inferior canalicular laceration were divided into control group and laser-directing group. The distance between the lacrimal punctum and the nasal broken end of lacerated lacrimal canaliculus was more than 6 mm. During the course of management of eyelid trauma, the patients were treated by canalicular anastomosis operation with traditional method and laser-directing method in searching for the nasal broken end of lacerated lacrimal canaliculus respectively. The silicone tube of 1 mm diameter was intubated in the lacrimal passage as a stent for 4 to 6 months.Results: In the laser-directing group, the mean time in searching for the nasal broken end of lacerated lacrimal canaliculus was (5.75±1.49) minutes and the mean time of operation was (49.21±3.37) minutes; both were significantly shorter than that of the control group (P<0.01). The cure rate of the laser-directing group was 96.55%, higher than that of the control group but without statistical significance (P>0.05). Conclusions: The laser-directing method is much quicker and more convenient to searching for the nasal broken end of the lacerated lacrimal canaliculus than the traditional approach, and patients suffer less pain and damaging in canalicular anastomosis operation.
