A red incision line can be seen on the upper eyelid within 2-3 weeks after canthotomy, which will gradually turn into skin color.
Because the skin tension of the upper eyelid is not great, there is generally no scar. The recovery time of canthus is related to the doctor's operation, postoperative nursing and the patient's physique.
Generally speaking, the swelling is obvious within one week after canthotomy, and gradually decreases in 2-3 weeks, and completely subsides in 1-3 months. It is suggested to use some anti-inflammatory antibiotics to prevent infection.
