1, embedding: generally it will last for about 5 years;
2. Bilateral continuous catgut embedding: the maintenance time is about 5- 10 years;
3, incision: maintain a lifetime.
The maintenance time of double eyelid surgery needs to be determined according to the shape of eyelid. For example, the eyelids are aging and slack, and the eyelids may gradually narrow, and even the shape of the eyelids cannot be observed. Fat atrophy can lead to eye depression or triple eyelid formation, all of which occur in the process of aging. In addition, embedding thread will lead to structural deformation, that is, double eyelid surgery fails because the suture falls off.
