Old tears after having eye bag surgery may be caused by increased secretion of tears due to infection stimulation of the lacrimal glands during or after surgery, or it may be relieved by bad rest through tears, etc. There are many specific reasons for tears after eye bag surgery. The increase in secretion may be caused by inflammation and infection of the tear-related glands during surgery or postoperative recovery, or it may be due to the excessive fatigue of the eyes from bad rest after surgery, which needs to be relieved by the excessive secretion of tears. In other cases, the tear ducts may be blocked, such as the lacrimal puncta and the lacrimal ducts, which are common in the elderly, or in rare cases, the tear drainage structures may be damaged during surgery. It is recommended that if the above mentioned abnormalities, such as increased tearing, have a significant impact on your psychological well-being or your life, you should seek medical attention and have the cause clarified by performing auxiliary examinations, such as lacrimal flushing.
