The Study of a New Modified Bicanalicular Intubation for the Repairment of Traumatic Canalicular Laceration

Introduction. To investigate the efficacy and safety of a modified bicanalicular intubation (MBCI) used in canalicular laceration. Materials and Methods. This study is a retrospective consecutive chart review. A total of 43 eyes from 43 patients (36 males and 7 females) who underwent canalicular intubation were enrolled. Success rate was determined at 6months after the surgery. Anatomical success was determined by diagnostic probing and irrigation; functional success was determined by asking patients about tearing. Results. Irrigation of the lacrimal passages in all 43 eyes showed that they were free from obstruction. The anatomical success was 100%, and 37 eyes (86%) achieved functional success. 6 eyes (14%) could not achieve functional success because there were some residual symptoms under irritating conditions, such as wind or winter weather, among which 2 eyes had bicanalicular lacerations and 4 eyes had lower canalicular laceration before surgery. There were no other complications observed in this study. Conclusions. The MBCI was simple and safe for using in canalicular laceration.
