Comparison of transcanalicular diode laser dacryocystorhinostomy and external dacryocystorhinostomy in patients with primary acquired nasolacrimal duct obstruction

Abstract

Although EX-DCR success rate was higher than that achieved with TCDL-DCR, the latter, with its shorter duration of surgery, lower perioperative complication rate, and a similar success rate, may be a good and acceptable surgical alternative in treatment of primary acquired nasolacrimal duct obstruction.
