Canalicular laceration, especially lower canaliculus laceration, is the most common type of trauma of the lacrimal system. The primary aim of management of these cases is to restore the canalicular system both anatomically and functionally. Previously, we have successfully developed a modified soft probe to treat lacrimal passage obstruction.1 ,2 Herein, we reported a novel and simple procedure to identify the distal cut end of the lower or upper canalicular laceration by intubation of a modified soft probe through the uninjured ipsilateral canaliculus.
This study was a non-comparative, interventional case series. Thirty-six eyes with lower or upper canalicular lacerations (lower, 33 eyes, and upper, three eyes) as a result of trauma were involved in the study. A modified soft probe system was developed for this procedure including a segmental epidural catheter with the blind tip (with a self-made side aperture 2.0 cm from the tail end), a stainless steel acupuncture needle (needle point was cut-off and the tip was burnished) which was inserted into the lumen of epidural catheter to increase its rigidity, and a syringe which was used to inject oculentum (figure 1A). Under an operating microscope, the …
