In order to avoid infection of the wound after the patient's outpatient surgery, and to ensure the primary healing of the wound, most wounds need to be changed dressing 1-2 times.
For general wounds, such as double eyelid surgery, eye bag resection, rhinoplasty, eyebrow lift, mole resection, scar resection, etc., the dressing will be changed one day after surgery (not counted on the day of surgery, full 24 hours is one day). First open the pressurized dressing, clean the blood scab with hydrogen peroxide to prevent the hydrogen peroxide from entering the eyes and irritate the cornea, then clean the wound with a saline cotton ball, and finally apply erythromycin eye ointment.
