A Simple New Method for Identifying the Proximal Cut End in Lower Canalicular Laceration

PURPOSE We report a simple and effective method of identifying the medial cut end of lower canalicular laceration cases. METHODS Twenty-seven eyes with lower canalicular lacerations as a result of trauma were involved in the study. Surgery was performed within 48 hours after injury for canalicular reconstruction. Upper canalicular probing was utilized to identify the medial cut end of deep canalicular lacerations when difficulties were encountered. Total time from the initiation of the probing procedure to the identification of the medial cut end of the lower canaliculus was measured. RESULTS A total of 27 eyes with lower canalicular lacerations were reconstructed. In 20 eyes, the medial lacerated end was located by upper canalicular probing. The mean time from initiation of the probing procedure to identification of the medial cut end of the lacerated canaliculus was 2 minutes. CONCLUSIONS We conclude that upper canalicular probing in patients with lower canalicular lacerations significantly reduces the time from the initiation of the operation to the identification of the medial cut end of the lower canaliculus.
