The use of Medpor coated tear drainage tube in conjunctivodacryocystorhinostomy.
OBJECTIVE
To analyse outcomes of lacrimal bypass surgery with the Medpor coated tear drainage tube.


METHODS
A total of 26 eyes in 26 patients with persistent epiphora who failed canaliculoanastomosis and dacryocystorhinostomy were treated by the lacrimal bypass surgery with the Medpor coated tear drainage tubes. Ten cases of severe obstruction of punctum and canaliculi and 16 cases with both upper system and lacrimal sac obstruction comprised this cohort of patients.


RESULTS
No tube extrusion or displacement was observed after 6-28 months of follow-up. Complete or significant resolution of epiphora was achieved in 23/26 cases (88.5%). Luminal obstruction by debris was noted in nine eyes, ocular discomfort in four, improper tube size selection in two, malposition in one, infection in one, diplopia in one, corneal abrasion in one, and reflux of intranasal secretion into fornix in another.


CONCLUSIONS
Medpor coated tear drainage tube offers tube stabilization in minimizing tube extrusion and displacement.
