title: Postcataract surgery endophthalmitis in a patient with a functioning Jones tube.
abstract: Dacryocystorhinostomy with Jones tube placement has proven to be an effective method for correcting upper-system lacrimal drainage obstruction. The present case report illustrates the potential risk of bacterial contamination of the operative field during subsequent cataract surgery by retrograde passage of airway secretions. Temporary occlusion of the Jones tube by a silicone plug can eliminate this potential source of endophthalmitis. In addition, temporary occlusion of the Jones tube in the office can be used to determine the effectiveness of lacrimal drainage through a reconstructed canalicular system.
