Double eyelid surgery is a procedure that requires a high level of skill on the part of the surgeon to repair a failed double eyelid surgery. After a double eyelid surgery failure, whether it is a minimally invasive double eyelid surgery or a Korean three-dot double eyelid surgery, it can be repaired by double eyelid repair surgery. The best time for double eyelid repair can be divided into two phases: early repair and stabilization repair: 1. Early repair: If there is a serious morphological or functional problem of double eyelid after surgery, as well as the symptom of failure has been seriously affecting daily life and causing psychological obstacles, it can be repaired at an early stage. Candidates who had their first double eyelid done in a relatively formal institution, where the eye tissues were not excessively damaged, can be considered for repair within a week; 2. Stabilization repair: it is generally recommended to repair the eyelid 6 months after the surgery when the shape of the blepharoplasty has been finalized. For those who have just had blepharoplasty, it is difficult to accurately determine the final effect of the blepharoplasty because the tissues are in an edematous state at an early stage, so it is not recommended to perform the repair immediately. It is also recommended to go through the scarring period 1-3 months after eyelid surgery, as this can stimulate scarring, so it is best to go through the scarring period.
