Kaneka Stents for the Treatment of Nasolacrimal Duct Obstruction

Introduction: The Kaneka Lacriflow Stent is a newly introduced self-retaining bi-canalicular intubation set, which can be placed without retrieval from the nose. The simplified insertion process decreases intraoperative time and intranasal trauma. The stent is not tied in the nose and can be removed easily in the office. We review a cohort of children to evaluate the success rate of stent placement for NLDO.
Methods: Stents were placed in an outpatient surgery center under general anesthesia in pediatric patients. The stent is placed with a stylet through both punctum and self-retains due to a widened portion sitting distal to the common canaliculis in the lacrimal duct and sac. It does not require recovery from or removal from the nose.
Results: Children were between the ages of 1-12 years. Stents were left in place for 3 months. Stent’s were placed successfully in 11 of 14 eyes. Two eye’s of 2 different patients were not able to have the stent placed. There was an improvement in symptoms in all 8 eyes of 7 patients who we have follow up data on.
Discussion: Kaneka Lacriflow stents can be removed easily in the office without entering the nose making them ideal for use in children. A new insertion technique, bending the stylet should allow it to be used in even the youngest children.
Conclusion: Kaneka Lacriflow stents can be successfully placed in children to treat epiphora.
