Purpose: To determine the intranasal causes of failed dacryocystorhinostomy (DCR) and the effects of transcanalicular diode laser-assisted revision surgery.
Methods: Twenty-four patients (29 eyes) who underwent revision surgery for a failed DCR at the Department of
Ophthalmology, Ansan Hospital, Korea University between March 2009 and February 2011 were included in the present
retrospective study. The intranasal causes of failed DCR, the time of symptoms such as epiphora and discharge after
DCR, success rates of revision surgeries and follow-up periods were evaluated.
Results: Membranous obstruction was found in 25 eyes (86.2%) and was accompanied with granuloma in 10 eyes; these were the most common causes of failed DCR. The mean time for symptom development after DCR was 14.6 months, the success rate of the first revision surgery was 82.1% and good results were obtained in 5 eyes after the second revision surgery. Recurrence developed in 2 eyes, but symptoms improved after the lateral tarsal strip procedure.
Conclusions: Membranous obstruction was the most common intranasal cause of failed DCR and anscanalicular diode laser-assisted revision surgery produced good results. Additionally, in patients with persistent epiphora following anatomically- patent revisional surgery, lacrimal pump failure due to lower eyelid laxity should be considered and
corrected.
