• The standard glass tube used with a conjunctivodacryocystorhinostomy is subject to spontaneous displacement. Either internal displacement into the surgically created passageway or external displacement and loss are possible. We have modified the tube by adding a flange 4 to 6 mm from the tube's top. This anchors the tube and significantly reduces postoperative tube mobility. Many procedures that would otherwise fail can be salvaged by using this new tube.
