• On the day upon completion of operation, you can get out of bed and use the toilet.
• If there is no vomiting after the operation, you can eat liquid food, and then a normal diet the following day.
• Use antibiotic eye drops or ointments as directed by your doctor to prevent eye infections and inflammation. Use the medicine for about 3 weeks.
• If pus-like discharge occurs again on the affected side, it may be a recurrence of dacryocystitis. Hospital visits should be made to determine whether medication or surgery should be given.
