Dacryocystorhinostomy (DCR) is a minimally invasive procedure to treat a blocked tear duct. Using diode laser - DCR, an opening is created in the nasal lacrimal sac wall to bypass the blocked tear duct. The outflow of tears is repaired successfully. Our FOX 810 and FOX IV 810 diode lasers with the corresponding DCR probe are ideally suited for this procedure.
