Double eyelid surgery is one of the most common surgeries in plastic and cosmetic surgery, but each person is different, and it is not easy to make each surgery satisfactory. 1, the choice of surgical methods: there are mainly two kinds of incision and buried line. The so-called pressure line, Korean style, minimally invasive, polymer and so on, are also variations of these two ways. There is no surgical method suitable for all patients, and no method is the most advanced. It needs to be decided by your doctor according to your situation. 2, the shape of double eyelids: there are parallel, internal fan-shaped, external fan-shaped. According to the oriental aesthetics, most people choose the small outer fan shape, this issue does not need too much entanglement. 3.Width of double eyelids: generally about 7mm, in most cases to the physician to decide. If you are an actor to exaggerate some, you can explain with the physician. The width of the double eyelid is just an approximation, not the physician can be measured accurately, the final width is also with the healing time and change. 4, whether to open the corner of the eye: open the corner of the eye because more or less some scars, especially the first year will be more obvious. Whether or not to open, need to weigh, and the physician to discuss the decision. 5, the problem of ptosis: our black eye is called the cornea, and there is a pupil in the center. The normal upper eyelid margin is located between the upper edge of the cornea and the upper edge of the pupil. The size of the pupil changes with the intensity of the light, so the normal level of the upper eyelid margin is a fairly large range. The muscle responsible for opening the eye is called the levator muscle. If the levator muscle is not well developed and strong enough, the upper eyelid margin will not be able to reach the normal level of opening the eye, which can be either mild or severe, and in severe cases the pupil will be covered, so the parents will bring it to the doctor when the child is young. Mild is not easy to detect, although also belongs to the normal range, just the eyes are not too open, black eyes more cover a part of the appearance of no spirit, did not wake up, often unconsciously raise their eyebrows when they open their eyes to increase the power to open their eyes. Single eyelids have a considerable number of such mild ptosis, and double eyelid surgery requires the removal of an orbicularis oculi muscle, which damages some of the tissues and may worsen the ptosis, a problem that many practitioners are under-recognized. Your ophthalmologist will say you are normal if your upper eyelid margin is just a little bit above your pupil, and you unconsciously raise your eyebrows to open your eyes wider when you open them, further masking the problem. And as we think more about the aesthetics of our eyes than the pathologic abnormality, there may be some different views or even misunderstandings about this problem. To solve this problem, it is necessary to shorten the upper eyelid muscle at the same time as the incision method of double eyelid surgery, which can make the eyes open a little bit wider and appear to have a sense of humor and much brighter eyes. Otherwise, even if you make double eyelids, it is also a false feeling, no God. 6, scar problem: any surgery has a scar, when the stitches are removed, there is no scar, and only after that it starts to proliferate, peaks in 3 months, and takes 1 year or even longer to fade away. Whether or not it is noticeable in the end is related to many factors, including your personal constitution. When scarring occurs, it also affects the shape and aesthetics of the eyelids. So all surgeries need a recovery period. 7, the problem of restoration: even the best doctor can not guarantee foolproof, no doctor dare to say 100% success and package your satisfaction. It is difficult to judge the swelling of anesthesia with absolute accuracy, and the personal recovery after surgery is beyond the control of the doctor, and it takes a few months of recovery to finalize the shape. Therefore, it usually takes 3 months to repair again. In fact, many good surgical results are also achieved after 1-2 times of repair.
