title: Failure of collagen plugs to predict epiphora after permanent punctal occlusion.
abstract: In two patients with keratoconjunctivitis sicca, epiphora did not occur after temporary canalicular occlusion with collagen implants, but did occur after subsequent permanent punctal occlusion. This suggests that collagen implants may not always produce total occlusion. Patients should be warned of this possibility.
