title: [Microendoscopic tear duct surgery].
abstract: Transcanalicular microendoscopy of the lacrimal system has brought great advantages in knowledge and our understanding of the pathophysiology of the lacrimal system. It has now been confirmed that the causes of most primary idiopathic stenoses are often spot-like stenoses located at the site of anatomically preformed folds in the efferent tear ducts. Minimally invasive procedures of rechanneling have been developed, such as laser dacryoplasty and microdrill dacryoplasty, which preserve lacrimal pump function, result in much less stress for the patient and for a first-step procedure have an acceptable success rate of 80%.
