The main surgical methods of double eyelid plasty are the buried thread method, the Korean three-point minimally invasive method, and the incision blepharoplasty method. Embedded thread method is a method that fixes the ligature thread between the upper eyelid dermis and the upper eyelid tendon membrane of the upper eyelid tendon membrane in front of or on the upper edge of the eyelid plate to form a heavy eyelid crease. It is suitable for young people who have large eyelid fissure, thin eyelids, no bloating, no eyelid skin laxity, normal tension, no inner canthus, and little orbital fat in the upper eyelid. The advantages of this method are the natural shape of the crease formed by the double eyelid, no incision, small postoperative tissue reaction, and no impact on work. If it becomes narrower in the future, there is still room for re-cutting, which is easy to be accepted by the candidates. However, the disadvantage of this method is that the upper eyelid crease can easily become shallow and narrow, or even disappear. The thread knot is buried too shallow, easy to be exposed or form small cysts. The Korean 3-point minimally invasive method is also known as the Korean double eyelid, which is often heard of by beauty seekers. It is a semi-open double eyelid surgery method that makes 3 small, discontinuous wounds on the eyelid with a length of only 2~3mm. The eyelids are fixed through these 3 small discrete incisions, and fat can be removed from the eye blisters at the same time. It is suitable for people who do not have excessively loose upper eyelid skin and who do not have excessively bloated upper eyelids. Korean double eyelid surgery lines are not only natural and beautiful, the formation of the eyelid effect image realistic, can be maintained permanently, and postoperative wounds are small, swelling fast, recovery is also fast. Incision blepharoplasty is a longer blepharoplasty procedure. Because it can regulate and change the tissue structure of the upper eyelid at all levels, it can solve many complex problems of the eyelid, such as upper eyelid skin laxity, eyelash inversion, upper eyelid bloat, orbital fat sagging, orbital septum laxity, and external supraorbital rim bulging. The incision blepharoplasty creates a solid and long-lasting eyelid with a deep, three-dimensional crease. However, the disadvantage is that the surgery is more complicated and requires familiarity with the anatomy of the eyelid, and the surgeon should have a solid foundation in plastic surgery. There are several main types of blepharoplasty. In practice, the surgeon will choose the type of surgery based on the condition of the patient (e.g., shape of the eyelid, shape of the face, etc.), and will not apply one type of surgery to everyone, but rather, each type of surgery will be different from one person to another. Each procedure is customized to the individual, so that the result will match each candidate’s condition, emphasize individuality, and achieve a perfect result.
