Generally speaking, double eyelid surgery failure is mainly realized in the following aspects. First: the double eyelid is too wide. Secondly, the eyelids are too low. Third: Asymmetry of the eyelids. Fourth: double eyelids disappear. Fifth: the formation of triple eyelids. The occurrence of this condition can determine whether the double eyelid is a failure. Double eyelid repair can be divided into two periods. Early repair: Double eyelids with serious morphological or functional problems within one week after surgery, as well as symptoms of failure that have seriously affected daily life and caused psychological barriers, can also be repaired early. Candidates who had their eyes done for the first time in a relatively regular institution without excessive damage to the eye tissues can consider repair within one week. Stabilization period: around 6 months For those who have just had blepharoplasty, immediate restoration is not recommended because the early tissues are in a state of edema and it is difficult to accurately determine the final result of the blepharoplasty. It is best to repair the eyelid after the scar growth period (3-6 months), as this period can stimulate scar growth again.
