Laser DCR


Dacryocystorhinostomy (DCR) is performed to connect the lacrimal sac directly to the nasal mucosa in order to bypass a lacrimal sac or nasolacrimal duct obstruction. The approach to a DCR can be via an intranasal or external route. Endoscopic laser dacryocystorhinostomy (DCR) enables an obstructed lacrimal sac to be opened an intranasal approach, avoiding the need for skin incision. Endoscopic instrumentation allows the rapid identification and correction of intranasal causes of DCR failure, including ethmoid sinus disease and middle turbinate hypertrophy.
