Ninety-eight cases of nasolacrimal duct obstruction including 6 bilateral cases were included in the study done at Postgraduate Institute of Medical Research, Chandigarh. All the cases had been divided into three groups with Group I including cases in which 12 endoscopic dacryocystorhinostomy (DCR) with dilatation and probing and stent insertion were performed. In Group II, 23 Endo DCR performed with intraoperative dilatation and probing but no stent insertion. Group III included 69 cases of Endo DCR without dilatation and probing and no stent insertion. Overall success rate was found to be 94.3% with Group III cases having a success rate of 97.1% and was found statistically significant on comparing with that of Group II (p value: 0.03).
