ObjectiveTo evaluate the success rate of Transcanalicular Diode laser assisted Dacryocystorhinostomy (TC-DCR) in cases of acquired nasolacrimal duct obstruction (NLDO).MethodsThis Quasi-Experimental study was conducted in Armed Forces Institute of Ophthalmology (AFIO) Rawalpindi, from July 2018 to April 2019. In this study, 73 patients of chronic dacryocystitis secondary to acquired NLDO were treated by TC-DCR under general anaesthesia. Follow up examination was done after one day, one week and three months. Silicone tubes were removed three months after surgery and syringing of lacrimal system done to confirm patency of lacrimal passages. Success of the procedure was documented as absence of epiphora and patent nasolacrimal duct on syringing.ResultsSeventy three patients (males 27; females 46) were included in this study. Mean age of these patients was 51.6+21 years. On completion of this study which was three months after surgery, we found subjective improvement (absence of epiphora) in 86.3% patients and objective improvement (successful irrigation of lacrimal passages) in 93.2% patients.ConclusionTC- DCR is a minimally invasive technique of doing Dacryocystorhinostomy and imparts more than 90% success rate. It has additional advantages of good cosmetic results, low complication rate and short surgery and convalescence time.Copyright: © Pakistan Journal of Medical Sciences.
