Double eyelid surgery has a certain failure rate, common failures of double eyelid surgery include poor alignment of the incision edge, improper design, bilateral asymmetry caused by too wide, too narrow, too long, too short design line, asymmetry of double eyelid shape and features or disappearance of double eyelid line, etc. After surgery failure, double eyelid repair can be performed according to the main problems after surgery, as follows: 1. too wide, a strip of skin can be removed under the incision to make the double eyelid narrower; 2. If the double eyelid is too narrow, you can also make another slight incision on the incision to make the double eyelid wider; 3. If too much fat was removed, the fat of the orbital septum may be released or fat grafting may be done to fill the depression in the orbital area. In addition, there are some cases, such as double eyelid asymmetry, which can be repaired differently depending on the asymmetry. It is best to wait until three months after the first surgery before repairing, because after three months the scar has basically relaxed and it is relatively easy to repair and the postoperative scar is not too obvious. However, the repair surgery is generally more difficult, and the success rate of the repair is lower than the success rate of the first surgery, and the cost will also increase accordingly, so patients should be cautious about the first surgery.
