How to repair the double eyelids depends first on the original double eyelids: whether there is a problem of width, radian, incision scar or no swelling under the double eyelids, whether there is a double eyelid under the double eyelids, whether the internal tissues of the double eyelids are piled up, and whether the eyelashes are tilted. There are many cases, and how to repair them depends on the patient's own situation. If it is relatively complicated to narrow the width and narrow the wide double eyelids, it is necessary to divide the original double eyelid width with tissue and then form new double eyelids, which is relatively complicated. Narrowing and widening is mainly to remove some skin scars at the upper end of the incision, and then to widen the double eyelids by hanging the tarsus high, which is relatively simple. As for the restoration of radian and shape, it is mainly decided when designing and hanging tarsal bones.
