There are several common types of double eyelid: 1, buried line: mainly for eyelid skin is very thin, less fat, thin muscle and eyelid fissure is larger, eyebrow-eye spacing is higher, that is, the overall eye conditions of the population is better, common young people, buried line double eyelid recovery faster, routinely in about 2 weeks, all the swelling and bruising will subside, if the failure of the latter part of the repair is relatively simple; 2, Korean style: that is three points, suitable for young people, that is, the skin is relatively not loose, even if there is a slight laxity, three points routinely not necessarily three points, you can also choose two points, if you choose three points, you may not choose to do a full cut. That is, three-point, suitable for young people, that is, the skin is relatively not loose, even if there is a slight relaxation, you can not choose to do a full cut, three-point routine is not necessarily three points, you can also choose two points, if you choose three points, the routine outside can go a little bit of fat, even if the young people with mild skin laxity and the outside of the fat bloat can be solved by three points, relatively speaking, three-point recovery is faster, which between the buried line and the full cut, the recovery of three-point and the recovery of three-point. The recovery time is a little longer than the buried line, and the recovery time may be 3-4 weeks. 3. Full cut: mainly for patients with loose eyelids, fat muscle hypertrophy, narrow eye spacing, accompanied by ptosis, small inner canthus and congenital microphthalmos, the full cut not only removes the excess skin, orbicularis oculi muscle and orbital septum fat, but also repairs the upper eyelid ptosis and shortens or collapses the levator muscle to solve the eye problem. The overall effect will be very good if you do the eye corners at the same time to solve the eye problems. However, the recovery time of full incision will be a little slower than that of threading or Korean 3-point, the early swelling time is a little longer and the swelling will be more serious, the swelling will subside in about 1 month, but it will take 3-6 months to fully finalize the shape of the eyelid. So full incision has both advantages and disadvantages.
