Remaining 88 had either no tearing or significant improvement of tearing after 6 months follow up and patent lacrimal system by syringing without pressure. Success rate in this procedure was 97.77% (p-value < 0.001). This study showed very high rate of success. Only complication noted was excessive nasal bleeding which was easily controlled. Intraoperative Mitomycin-C application in external DCR is safe, effective, cheap adjunct that helps to achieve good results of DCR surgery.
