AIM: To investigate the effect, the catheterization feasibility and complications in canaliculus anastomosis.

METHODS: In 67 cases(67 eyes)of inner canthal angle or eyelid laceration of canaliculus anastomosis, the catheterization feasibility, complications, the retention time of catheter as well as extubation more than half a year's presented were studied.

RESULTS: In the 67 cases, there were 62 cases underwent successful anastomosis, lachrymal in 3 cases was narrow after extubation, 2 cases were impassability rinsing, lachrymal was unobstructed after YAG laser treatment.

CONCLUSION: Injury canaliculus ring immediately before intubation in the law, whether it has epiphora or not, can successfully catheter, and because the catheter retained in the nasal cavity, which can be maintained for a longer time, and does not affect the daily life, work, ensure no pull in repair under the condition of the broken end of the canaliculus, less complications, efficacy.
