The eyes are the window to the soul, and a beautiful pair of eyes can bring unparalleled confidence and beauty to one’s spirit and life. The Oriental eye shape is characterized by single eyelids, small lid fissures, bloated upper lids with subcutaneous fat, wide distance between the eyes, and some people with obvious inner canthus. As the standard of living improves, more and more people with single eyelids are pursuing three-dimensional double eyelids, and thus double eyelid surgery has become the most common cosmetic surgery in beauty clinics. There are two types of double eyelid surgery that are most widely used: the incision method and the buried line method, both of which have corresponding indications and their respective advantages and disadvantages. In general, the incision method is suitable for all patients, especially for those with bloated upper eyelids (commonly known as “swollen eyeballs”), inverted eyelashes, and older patients with loose upper eyelid skin. The incision method provides a stable and long-lasting double eyelid with a strong sense of dimensionality; it also corrects ingrown eyelashes and increases the eyelashes’ aura; it removes fat from the upper lid to make the upper lid less bloated and more beautiful; and it removes part of the skin and lifts the corners of the eyes to rejuvenate the upper lid skin. Some people are concerned that the incision method will leave a visible scar. This concern is not necessary: although there will be a scar in the early stages, it is usually less noticeable after six months, and the scar can only be seen when the eyes are closed, but when the eyes are open, the cut falls in the eyelid groove and is not easily visible. The stitches are usually removed in 4 days, leaving no trace of stitches. In addition, many years of clinical experience has found that even for people with scarring, it is not easy for hyperplastic scarring to occur in certain special areas, such as the upper and lower eyelids, eyebrows and other parts, so open double eyelid surgery can be used for people with scarring (except for eye opening surgery). 2, buried wire method double eyelid surgery buried wire method double eyelid surgery is relatively narrow scope of application. The following conditions are generally required: 1) thin eyelids; 2) narrow eye fissures; 3) young patients with no obvious laxity of the eyelids. However, after surgery, the upper eyelid crease may become shallow and narrow, and a small number of people may lose their eyelids and need to have surgery again. The width of the eyelid is usually between 5.5mm and 7.5mm for Chinese people, and the buried line method can be made wider (because the upper eyelid crease tends to become shallower and narrower after surgery), but too narrow can easily disappear; too wide, which is commonly known as “European eyes”, is not very suitable for Oriental people, because the brow bone is generally lower in yellow people, and the distance between the brow and the lid is shorter. The “European eyes” are generally fake. The blind pursuit of “European style eyes” will not achieve the cosmetic effect, but also bring difficulties to the later repair. The recovery time after double eyelid surgery varies from person to person, generally about 2 weeks has been a good recovery, individual time is a little longer.
