Purpose:
To determine the results with a Medpor-coated tear drain in conjunctivodacryocystorhinostomy.
Methods:
This was a retrospective case review of all patients who underwent conjunctivodacryocystorhinostomy with a Medpor-coated tear drain by the author. The success rate and complications were determined.
Results:
Sixteen patients had placement of 17 Medpor-coated tear drains. Twelve of the 16 patients (75%) were doing well at the last follow-up visit with a well-positioned, functioning tear drain tube. Four patients (25%) required tube removal for assorted reasons, 2 of whom had an early prototype of the tube.
Conclusion:
The Medpor-coated tear drain is an effective device for bypass of the lacrimal drainage system in conjunctivodacryocystorhinostomy. The current design of the tube should minimize complications while ensuring stable placement and retention.
