Double eyelid repair is a means of salvage for failed double eyelid surgery. It is mainly suitable for people who have lost the area of the heavy eyelid line, double eyelids forming triple eyelids after surgery, eyes with a triangular shape after surgery, and double eyelids that are too narrow in width and form an inner pair. At 1 month after the initial double eyelid surgery, it is possible to confirm whether the surgery has failed, but to avoid serious damage to the eye skin tissue, it is not recommended that patients undergo repair treatment immediately at 1 month. Patients are advised to wait 6 months after the initial surgery for the tissue to fully heal before undergoing double eyelid revision surgery. The recovery time after revision eyelid surgery is longer than the initial surgery, but the exact recovery time also varies from patient to patient as each patient’s body type is different. 2 weeks after the repair surgery is the period of rapid swelling reduction, when the basic shape can be seen; at 3 months the swelling basically subsides, but to avoid scar formation, topical anti-scar ointment is applied from the 2nd day after stitch removal for about 3 months continuously to prevent scarring.
