The method of double eyelid incision is a permanent double eyelid operation. Loose skin, orbicularis oculi muscle and fat are removed by incision, and the skin is directly sutured with orbicularis oculi muscle or levator palpebrae aponeurosis under direct vision to form double eyelid. This method needs to cut the skin, which is slightly traumatic, but the upper eyelid structure can be adjusted through the incision, and the effect is reliable and lasting, which is suitable for single eyelid in various situations. The swelling time is a little longer, and the wound will leave a linear scar.

Before Han minimally invasive suture embedding method, a small amount of fat was removed at one point, and then the double eyelid method of suture embedding was performed. The double eyelids formed by the advantages of Korean minimally invasive method are natural and realistic. There is no trace after operation, and it is more natural and beautiful to close your eyes. The postoperative recovery was quick and the postoperative swelling was small. Generally, it will be slightly swollen for 3-7 days, and it will completely return to nature in one month.

Thread pressing method, similar to suture method, is to suture mucosa through skin to form double eyelids. Because of the continuous suture of the upper eyelid, the vascular reflux is blocked, so the upper eyelid is obviously swollen and swollen slowly, and the stitches need to be removed, and the double eyelid may disappear.

Thread embedding method is to bury the suture directly between the skin and the meibomian through the suture, so that the upper eyelid skin adheres to the meibomian to form a double eyelid. This method is simple to operate, with little trauma, no scar, rapid swelling reduction and no need to remove stitches. It is more suitable for young people, elderly people with thin eyelids, chapped eyes and loose skin. Not suitable for people with thick eyelids, loose skin and older age, double eyelids may disappear.
