Double eyelid surgery is a very successful operation in cosmetic surgery. There are several surgical methods: double eyelid catgut embedding, double eyelid incision, double eyelid suture/seamless trichiasis, skin grafting and so on. At present, the most commonly used methods are double eyelid catgut embedding and incision. Double eyelid surgery should ban smoking and alcohol for the first two weeks, avoid pregnancy and menstrual period, and avoid oral aspirin or aspirin-containing drugs and Chinese patent medicines with the function of promoting blood circulation, because these drugs will aggravate double eyelid surgery's bleeding and may increase the risk of double eyelid surgery.
