(2) The operator’s skill is not good and the skin treatment of the incision is not good, resulting in postoperative edema that does not subside for a long time and an unnatural appearance; (3) The upper eyelid lift muscle is mistakenly injured during surgery or the upper eyelid lift muscle is not functional enough and is not corrected during surgery, so the eyes are not only not bigger after surgery, but also have a hard time opening the eyes and eyes (3) If the upper eyelid lift is not corrected during surgery, the eyes will not be enlarged, but will be strained to open, and the eyes will be dull.
