AIM:To analyze the reason of canalicular laceration, and to explore the methods and techniques to raise the success rate of lacrimal canaliculi laceration anastomosis.

METHODS: Seventy-eight cases(78 eyes)with canalicular underwent lacrimal canaliculi laceration anastomosis through catheter support under microscope at I stage.

RESULTS: The operation was successful in all cases. The extubation time was at 3 months after operation. After one-year follow-up, lower lacrimal canaliculi were all unobstructed.

CONCLUSION: The causes of canalicular laceration laceration mostly were frustrated laceration. Receiving anastomosis under microscope at I stage was preferred and necessary. Searching nasal stump, implanting epidural catheter and anatomical reduction of the inner canthus were the keys to make the operation successful. Fake tears could also drain tear.
