Cannula dacryocystorhinostomy: a simple, innovative and cost-effective method of lacrimal surgery

Abstract

To compare our innovative, cost-effective method of lacrimal surgery with other methods. A prospective cohort study. The study included 80 eyes of 80 consecutive patients who presented to our clinic between January 2009 and December 2011. The patients underwent surgery using a new technique with a specially designed cannula and were followed according to our protocol. Patency on irrigation. Of the 80 cases enrolled, the procedure was successful in 52.5 % with a mean follow-up of 247.2 days. The success rate was significantly affected by the preoperative conditions (p = 0.001) and follow-up duration (p = 0.006). This simple innovative technique was cost-effective and the results were comparable with those of other techniques.
