Lacrimal canaliculus obstruction: nonsurgical treatment with a newly designed polyurethane stent.
A newly designed polyurethane stent was used to successfully treat 30 eyes (in 28 patients) with epiphora resulting from obstruction of the lacrimal canaliculus. After stent placement, epiphora resolved in all eyes. During follow-up, epiphora recurred in 20 eyes, but epiphora did not recur and the lacrimal canaliculus was patent in 12 eyes after the stent was removed. The stent appears to be valuable for nonsurgical treatment of obstruction of the lacrimal canaliculus.
