To repair a torn tear duct, a Veirs malleable rod, modified so as to have a suture swaged to each end, is used to bridge the cut canaliculus. The pigtail probe of Worst is used to bring one suture back through the intact canaliculus. This maneuver eliminates the necessity of searching for the deeply positioned and difficult to find opening of the medial end. The suture on the other end of the rod is brought out through the damaged canaliculus and punctum. Both sutures are fastened to the skin to perfectly position the rod to splint the cut canaliculus.
