Silastic intubation for Canaliculus communis stenosis

Silastic intubation was performed for Canaliculus communis obstruction in 32 cases. Two eyes showed additional impatent nasolacrimal duct and were not treated. The silastic intubation was performed by aid of a long, hollow blunt injection needle which allows us to check the patency of the lacrimal system once the stenosis of common canaliculus is perforated. The success rate for isolated silastic intubation was 70%, which is similar to the results of other often more invasive surgical techniques for Canaliculus communis stenosis.
