Double eyelid surgery, also known as blepharoplasty, there are three main surgical methods: 1, full cut method: mainly in the upper eyelid to cut a pike-shaped incision, and then the pike skin removal, and then from the incision to remove part of the fat, and finally the incision will be sutured, while the upper eyelid and the eyelid plate will be fixed together to artificially form a crease, which will also form a double eyelid; 2, the Korean three-point method: also known as the half-cut method, mainly in the upper eyelid Three incisions of about 2mm in length are cut, and then part of the fat is removed from the incisions, and finally the incisions are fixed and sutured with the eyelids; 3. Embedded thread method: mainly absorbable protein thread is used to suture the upper eyelids directly with the eyelids. The comprehensive Korean fine-cut double eyelid is to innovate on the basis of the original full-cut double eyelid, to separate the anatomy of the eyelid area in finer levels, to adjust the upper eyelid muscle strength body according to the principle of bionics, and to reshape the upper eye muscle lifting, so as to make the double eyelid more natural, lifting and shaped, and the eyelashes naturally upward. Because the surgeon’s operation is more meticulous and skillfully avoids the neurovascular network of the eye, the surgical wound damage is smaller, the bleeding is smaller, the recovery time is faster, and the postoperative recovery effect is more like the natural double eyelids.
