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. There should be a quiet and comfortable environment to recuperate after double eyelid plastic surgery. When resting in bed, it is best to lie semi-supine (raising the pillow) to avoid excessive eye fatigue or lowering the head, which will aggravate the swelling of the wound. There will be some pain in the wound on the day of operation, but it will gradually decrease with time. Patients should not rush to take painkillers, because aspirin drugs will aggravate wound bleeding. After double eyelid incision, stitches were removed 5 ~ 7 days after operation. Sometimes the wound will leave a tiny thread after stitches are removed, which will be pushed out slowly or absorbed by itself over time.
