IN A PREVIOUS article1 a method of correction of strictures of the lacrimal canaliculi with polyethylene tubing was described and the possible use of this plastic material in restoration of the patency of lacrimal canaliculi destroyed by injury or disease was considered. Other investigators2 have been interested in this field and have used tubes or rods of plastic material for the restoration of occluded or stenosed lacrimal canaliculi and nasolacrimal ducts.
In the evaluation of any new method it is the passage of time that best permits judgment as to the permanent effectiveness of any given procedure. With this in mind, I contacted my patients in whom a lacrimal canaliculus had been reconstructed by insertion of a polyethylene tube. Accurate follow-up data were obtained on five of these patients. In this series, the longest interval that has passed since the procedure was performed was 38 months, and the
