Purpose: To evaluate the complications and the treatment results of SmartPlug-related complications.
Methods: Retrospective review of all patients from a single medical hospital who received SmartPlug (Medennium, Inc., Irvine, CA) insertions from October 2007 to February 2014. All patients who developed SmartPlug-related canaliculitis and pyogenic granuloma were analyzed. Lacrimal irrigation with antibiotics was performed in most patients.
Results: Six hundred thirty-one eyes received SmartPlug insertion and 18 eyes developed SmartPlug-related complications (14 canaliculitis and 4 pyogenic granuloma). The mean time interval from insertion to development of the complications is 3.0 (0.5-6.9) years. Sixteen eyes received lacrimal irrigation with antibiotics, and all the eyes showed improvement without recurrence. The other two eyes had recurrence of granuloma pyogenica only after surgical excision.
Conclusions: SmartPlug-related complications, including canaliculitis and granuloma pyogenica, required long-term follow-up. Most of the complications can be cured by lacrimal irrigation of antibiotics.
