Lacrimal surgery is a medical procedure aimed at treating issues related to the tear drainage system. This system includes the lacrimal glands, which produce tears, and the ducts that carry tears away from the eyes. Common conditions that may require surgery include blocked tear ducts or chronic tearing, which can lead to discomfort and infections. The surgery can involve various techniques, such as dacryocystorhinostomy, which creates a new drainage pathway for tears. It is typically performed by an ophthalmologist or an otolaryngologist and may be done under local or general anesthesia, depending on the complexity of the case.
