Traditional Korean double eyelid methods are nothing more than two methods, embedding thread and incision. The former is easy to disappear, and the latter is easy to leave scars. Korean double eyelids only have a small incision at both ends of the upper eyelid. After extracting fat and tightening the skin, natural double eyelids can be formed, leaving no trace after operation. Korean double eyelid surgery is suitable for all kinds of single eyelids. For loose upper eyelid skin, degreasing and peeling can be performed at the same time during the operation, and the postoperative effect is reliable, and the double eyelids can be maintained for a long time. Double eyelid surgery is an eye plastic surgery, which will not harm the eyeball and generally will not affect the vision. There may be swelling, irritation, fear of light, tears and transient blurred vision at the beginning after operation, but with the swelling after operation, the eyes will recover immediately.
