AIM:To investigate the clinical effect of using microscope to find the broken end of lacrimal canalicular and annular-intubation during traumatic lacrimal-canaliculi anastomosis.<p>METHODS:In 52 cases(52 eyes)with traumatic canaliculi laceration from March 2010 to December 2014, microscopy was used to find the broken end of lacrimal canalicular and annular-intubation implantation was performed during anastomosis. At 2～3mo after the surgeries, annular tubes were pulled out and patients were followed up for 3～12mo. <p>RESULTS:In all the 52 cases, 47 cases were cured, 3 cases were improved, and 2 cases were not healed. The 2 not-healed patients were cured after treated by laser. <p>CONCLUSION:The application of the annular-intubation for canaliculi laceration under the microscope is simple and the curative effect is reliable, besides, the the patients' appearance and normal work were not affected when the annular-tube was reserved. And it can reduce the incidence of eyelid deformity. Generally, it's a good methord for canaliculi laceration.
