Double eyelid surgery's methods generally include: catgut embedding, Korean-style three-point, total excision, and different fundus are suitable for different surgical methods. Catgut embedding and three points are minimally invasive, and minimally invasive methods are suitable for cases where the upper eyelid skin is thin, the skin is not slack and the subcutaneous fat is low. The effect is lasting. There is no need to remove stitches after operation. Generally, the swelling will be reduced in one week and recovered in 30 days. Total excision is suitable for cases with thick upper eyelid skin, loose skin and much subcutaneous fat. The effect of double eyelids is lasting, and stitches need to be removed after operation, which usually takes one to three months to recover. The price in double eyelid surgery is generally between 2000 and 8000, because different ways have different prices.
