Tear duct surgery is a fairly simple procedure that is performed under local or general anesthesia, according to the Digital Journal of Ophthalmology. Patients are usually able to return home the same day, states Johns Hopkins Medicine.
Tear duct surgery is performed to correct obstruction of the tear ducts, states Johns Hopkins Medicine. The endoscopic approach is performed entirely through the nostrils, so it does not involve cutting through the skin and leaves no scars on the face. In some procedures, the surgeon may leave a stent, or tiny tube, in the tear drainage system. This tube can be seen in the corner of the eye but is not bothersome. The stent is generally left in place for three to four months and then removed, according to EyeSmart.
