Blocked tear ducts usually require surgical treatment and are usually hospitalized for about 3 days. Lacrimal duct obstruction is a common ophthalmologic condition that is highly prevalent in middle-aged and elderly people, and is usually caused by chronic inflammation, trauma, and aging factors. Patients experience tearing of the eyes and usually require surgical treatment to eliminate the symptoms. Surgery usually requires about 3 days of hospitalization. The first day of hospitalization is mainly to further improve the coagulation function, blood routine, liver and kidney function, blood sugar and other tests to rule out contraindications to surgery; the second day can be arranged for surgical treatment; the third day to observe the postoperative recovery, if the recovery is smooth can be discharged. After discharge, patients usually need to be reviewed, and need to follow the doctor’s instructions for eye care, regular follow-up, and timely consultation when discomfort occurs.
