The principle of the double eyelid surgery is that a double eyelid thread is passed through the skin of the upper eyelid, compressing the skin and the lid to form double eyelids. If the patient is not satisfied with the double eyelid surgery, the threads can be removed as soon as possible after the surgery and the upper eyelid will be restored to its original state. Unlike a full eyelid cut, there is no incision of the upper eyelid during the procedure, but rather the buried thread is passed back and forth from shallow to deep within the skin of the upper eyelid, compressing the skin and the lid to form the double eyelid. If the patient is not satisfied with the threaded eyelid, the threads can be removed as soon as possible after the procedure. If the stitches have been in place for a long time and scarring has formed inside, removing the stitches at this time may cause injury to the upper eyelid skin. When the patient is not satisfied with the double eyelid surgery, it is recommended to go to the regular hospital in time, and under the communication with the professional doctor, to carry on the postoperative repair treatment.
