In order to have a safer and faster recovery after surgery, please read the following carefully: Nasal lacrimal sac anastomosis surgery is not done and everything is fine and dandy, in fact, post-operative follow-up and medication is also very important. It is generally recommended to follow up one week after surgery. During the follow-up, the doctor will examine, treat and administer medication according to the patient’s condition, including: Tear duct flushing: Since there will be secretions and blood leakage around the tear duct after surgery, these need to be flushed out through tear duct flushing, which can be done with iodopisol (tobramycin, dexamethasone eye drops) once more. Nasal medication: nasal rinses and nasal spray hormone medication can be used to prevent granulation scar formation. Medication guidance: Tobramycin dexamethasone eye drops 4 times a day or levofloxacin eye drops 4 times a day; pay attention to eye hygiene; light diet; outpatient review within 1 month after discharge, rinse the tear duct once a week for 4 weeks; after that, rinse once a month for 2-3 times. Follow up with outpatient clinic for discomfort.
