With the advances in medicine nowadays, more and more people who love to look good are seeking changes in their appearance. Double eyelid surgery is one of the most common surgical procedures. Patients with single eyelids or thick orbicularis oris muscles often give people a monotonous, mute and indifferent feeling. By changing the folds on the eyelids, the eyes can be made to look brighter and more attractive, which in turn promotes growth in self-confidence and improved interpersonal interactions. Usually, there are two types of double eyelid cutting, one is double eyelids with buried threads, and the other is double eyelids with full incision, commonly known as double eyelid cutting, which can be chosen according to different groups of people. There may be limitations to the buried eyelid, which is mainly for people with longer eye slits, thinner eyelids and better skin elasticity, and these people are more suitable for the buried eyelid. For people with swollen eyes, sagging eyes, and loose skin, it is recommended to choose the full incision double eyelid, which, in addition to its wide range of applicability, has certain advantages in terms of recovery time, technical sophistication, and postoperative results. After the surgery, the patient’s appearance will be improved, which in turn will serve to change the psychology. In principle, as long as the patient has no physical or psychological abnormalities, the surgery can be performed at a professional plastic surgery office. However, if the length of the patient’s eyelid fissure or the distance between the length of the eyelid margin and the arch of the eyebrow is less than 1.5cm, it is not recommended to perform the double eyelid surgery, so as to avoid poor results and affecting the appearance.
