Objective To explore the rational way for canalicular laceration by observing the curative effects of double-canalicular and nasolacrimal silicone intubation combined with canalicular laceration anastomosis.

Probing of lacrimal passage combined with neotype silicone nasolacrimal intubation in treating lacrimal passage diseases

Effect of KTP laser combined with neotype silicone nasolacrimal intubation on treating lacrimal duct obstruction

Methods Canaliculi breakages of 23 cases of lacrimal canaliculi laceration were found and anastomosised with epidural tube in the lacrimal canaliculars under operation microscope,and another end of the tube was implanted in the superior lacrimal canalicular.

The application of silica gel collapsible bulb in the ruptured inferior lacrimal canaliculus anastomosis;

Direct intubation and primary canaliculusostomy by microscopy for laceration of lower lacrimal canaliculus;

In order to improve the successful rate of anastomosis of broken lacrimal canaliculus, a new method of searching the broken ends of lacrimal canaliculus was developed.
