Double eyelid surgery is not good can be redone, but to be divided into several cases to consider, because double eyelid surgery at present there are mainly three kinds of practice: one, full cut method; two, half cut method, also known as the Korean three-point method; three, buried line method. The degree of damage of the three methods decreases in turn. In general, it seems that it is more difficult to repair the double eyelid with big damage, and it is relatively simple to repair the double eyelid with small damage, such as the buried thread method. After the double eyelid surgery, especially the full incision method, there is a swelling recovery process, generally about three months after the operation to see a better effect, so the short-term effect is not good, do not rush to redo for the time being. Because the effect of redoing is not yet fixed, it is impossible to predict whether the effect after redoing will be better than now, and it is better to wait for half a year after the operation when the effect is completely stabilized, and then consider whether to redo it or not.
