An Intravenous Catheter Used as a Lacrimal Trephine
Keywords:
Canalicular obstruction, lacrimal trephine, intravenous catheterAbstract
Objective: To describe a surgical technique of using a peripheral intravenous catheter to treat canalicular obstruction.
Methods: A peripheral intravenous catheter was used to treat canalicular obstruction instead of the commercial lacrimal trephine.
Five patients from January 2009 to March 2010 underwent lacrimal trephination using a 20-gauge intravenous catheter
followed by bicanalicular silicone stent intubation.
Results: Of five patients, three patients had common canalicular obstruction; two patients had distal canalicular obstruction,
with the obstruction sites 8 and 9 mm from the punctum. Improved epiphora and anatomic patency were achieved in four
cases. Minor complications included punctal laceration and a prolapsed stent.
Conclusion: Our technique used an intravenous catheter which is readily available in the operating room and is a safe and
an effective method to treat canalicular obstruction.
