Double eyelid surgery is a very popular modern plastic surgery procedure, which can make people’s eyes very beautiful. But double eyelid surgery also has certain risks, a little carelessness will lead to surgical failure. The main manifestations of double eyelid surgery failure are the following eight: 1, post-operative scarring: the occurrence of this situation is very much related to improper surgical operation and rough surgical process. In addition, if there is a wound infection after surgery, it will also increase the incidence of surgical scarring; 2, double eyelid disappearance: If the double eyelid surgery is done by way of buried eyelid surgery, the double eyelid may disappear after surgery because the sutures are loosened; 3, incomplete eye closure: It is mainly due to incomplete understanding of the anatomical structure of the eye, and the tissue and fat are removed during the surgery. 4. lower eyelid ectropion: due to the surgeon’s lack of clinical experience or skill, the orbicularis muscle may be damaged due to excessive roughness during surgery; 5. double eyelids too wide: 3-6 months after surgery, the eyelid should be redesigned, excess skin and tissue removed, adhesions from the previous surgery removed, and finally sutured to form a beautiful heavy eyelid 6. Narrow eyelids: After the swelling has subsided, a second stage of surgery is required, where the incision line is moved up to make a new incision, and the old and new incisions are peeled down to make the new and old incisions an integral part of the eyelid, and then the eyelid is sutured together. The trichiasis phenomenon can occur for reasons such as local application of anti-scarring medication, or by using toothpick-assisted scratching and practicing eye-opening and eye-closing movements to help with heavy eyelid formation.
