Abstract :
Purpose: To evaluate the incidence and severity of intra operative and Postoperative complication and success rate of transcanalicular laser DCR and compare it with conventional external DCR.
Method: This is a prospective randomized interventional comparative clinical study. In which 163 patients having complain of epiphora due to nasolacrimal duct obstruction were included. 168 operations were done out of which 79 patients underwent TLDCR and 84 patients underwent External DCR (Ext DCR) surgery. Patient between the ages of 15 to 65 yrs were included. Patient were evaluated postoperatively after one week, two week, one month, two month, six monthly and one yearly. Postoperatively patients were evaluated for improvement of symptoms and patency of nasolacrimal duct system by irrigation with syringing. Success were defined as patent lacrimal passage.
Result: TLDCR and Ext DCR both treatment modalities are equally good for management of nasolacrimal duct obstruction. But Intraoperative and postoperative complications are less with TLDCR as compared to Ext DCR.
Conclusion: In this prospective clinical trial TLDCR was minimally invasive surgical technique with less complication rate as compared to Ext DCR but result were same in both the procedures.
