Positioning eyelids and eyelid surgery are two different types of blepharoplasty. Positioning eyelids, also known as Korean 3-point eyelids, are semi-open eyelid surgeries with wounds between the suture and open eyelid surgeries. Sewing double eyelid can be done by burying the suture directly between the skin and the eyelid, which makes the upper eyelid skin and the eyelid adhesive to form a blepharoplasty effect. The difference between these two ways is as follows: 1. Positioning double eyelid surgery can make three tiny discontinuous incisions on the eyelid with a length of only 2-3 millimeters, and then bury the suture to fix it, with tiny scar on the eyelid after the surgery, fast swelling and short recovery period; buried eyelid surgery only needs to bury the suture, no incision, no scar; 2. Positioning double eyelid can deal with part of the problem of fat in the eye due to the existence of incision; buried eyelid As there is no incision, the fat cannot be removed; 3, the durability of the positioning eyelid surgery is better than the buried eyelid surgery, but both are not permanent; 4, the positioning eyelid surgery is suitable for 18-25 year olds who do not have loose skin on the upper eyelid; the buried eyelid surgery is suitable for young people who have thin upper eyelids and no fat.
