Dacryoendoscopy with its minimally invasive approach is suitable as a first-step procedure in lacrimal surgery. The absence of a scar and the quick recovery are vitally important for the patients. Medically important is that the topographic anatomy is preserved by using dacryoendoscopy, so other surgical techniques can be performed later without limitations, if necessary. Patients with incomplete obstructions and a localization of stenosis, being pre- to intrasaccal, profit from this treatment method in particular.
