Figure 2

Canalicular repair. A lower canalicular obstruction is shown in (a). A probe is inserted to the obstructed site, and a vertical incision about 5 mm is performed according to the site (b); after inserting a probe from upper canalicular punctum to expose the distal end on a vertical axis of the probe, a pair of scissors is used to cut out scar tissue at the distal canalicular end (c); bicanalicular silicon tube intubation is performed through the reopened canaliculus into nasal cavity (d); 2-3 pairs of sutures are placed around the two ends of canalicular lumen (e); finally, the skin wound is closed with 2-3 stitches (f).
