Our aim is to describe how we perform laser transcanalicular modified dacryocystorhinostomy (DCR) the departments of ENT and Ophthalmology in HURH in Valladolid as surgical treatment of primary acquired nasolacrimal infrasacal duct obstruction (PANDO). PANDO is a common disorder in middle aged an older patient leading to chronic epiphora and blepharitis as well as recurring or chronic dacryocystitis. In the treatment of PANDO, external dacryocystorhinostomy (DCR) is still considered to be “the gold standard” with success rates above 85%. However, in recent years external DCR is considered an invasive procedure that puts at risk the medial structures of the eyelid including the physiological canalicular pump mechanism and leave pa-tient with an uncosmetic scar. These risks are potentially avoidable by performing less invasive techniques or choosing an endonasal approach (endoscopic or laser modified). One disad-vantage of laser modified surgery is the economic inversion because of the high cost of the equipment and maintenance.
