AIM:To discuss the method of finding the rupture point of the lacrimal canaliculus and the result of applying the line-drafted silicone tube in the nasolacrimal anastomosis. ·METHODS:Retrospectly 18 cases 18 eyes with lacrimal canaliculus rupture in our hospital in the past five years were studied,the research contained the method of seeking the rupture point of the lacrimal canaliculus under the operating microscope and the result of using of the silicone tube as a support for lacrimal canaliculus for nasolacrimal anastomosis. ·RESULTS:Totally 18 cases were all successful and irrigation of lacrinal passages was good in half a year. ·CONCLUSION:Seeking the rupture point of the lacrimal canaliculus under the operating microscope is easy and implanting the silicone tube as a support can make patients more comfortable and reduce postoperative complications.
