Intubation in Lacrimal Surgery: Devices and Techniques

Abstract

Lacrimal drainage obstructions causing epiphora is a common lacrimal disorder. Depending on the age of the patient and the pathophysiology of the condition, the disorder can either be relieved by simple probing or by a dacryocystorhinostomy (DCR). In certain conditions, the success rates of the treatment can be improved by intubating the lacrimal system. Canalicular intubation is also indicated in the management of lacerated canaliculus. Intubation is achieved commonly by placing a silicone stent in the lacrimal passages. The silicone stent maintains the passages where it is present and is also believed to allow tissue healing around itself, thus maintaining lacrimal patency.
