Lacrimal duct obstruction can be treated with medication, lacrimal irrigation, lacrimal laser, lacrimal duct placement, or nasal lacrimal sac anastomosis as prescribed by the doctor. The beginning of the lacrimal duct is narrow, shallow and connected to the conjunctival sac, which makes it susceptible to inflammation and obstruction. If the tear duct is blocked due to inflammatory secretions, patients can be treated with antibiotic eye drops such as levofloxacin eye drops to control inflammation and promote the patency of the tear duct. Patients with tear duct obstruction can also be treated with tear duct irrigation or tear duct laser therapy. Irrigation and pressure can flush away the inflammatory substances in the eye, and laser can unclog the tear duct and relieve the patient’s discomfort such as tear overflow. Lacrimal duct placement is a common treatment for tear duct obstruction, as it supports the obstructed area by placing a tube, which can unclog the tear duct in a short period of time. Nasal lacrimal sac anastomosis is to act directly on the blocked area to make the tear duct open. Patients should use tobramycin drops and other medications under the doctor’s guidance after the surgery to prevent infection. It is recommended that patients with blocked tear ducts seek prompt medical attention to assess their condition and follow the doctor’s instructions.
