Under the impact of the development of plastic and aesthetic technology, a variety of methods of double fold plastic surgery have been derived, including embedded double fold, Korean double fold, eyelash raising double fold and so on. In addition to the doctor's skills, your own knowledge will also affect the effect of the eyelid surgery.

1. Length of eyes

The length of the eye is an important factor affecting the surgical effect. The longer the eye, the more natural the surgical effect. If people with short eyes want to have an effect, they can open the inner and outer canthus while doing double eyelid surgery, so that the eyes will be more beautiful.

2. Concavity of eyeball

With the eyebrow bone as a reference, the convexity of the eyeball can be divided into three situations: concave, flush and protruding. In the case of sunken eyeballs, the double eyelids can be slightly wider, which is more like the eyes of Westerners. The slightly wide double eyelids do not appear abrupt on the sunken eyes, but more exotic.

Most of Asians' eyeballs are flat, and such eyes are not suitable for making the double eyelids too wide, so as not to leave an unreal feeling. The exophthalmos caused by congenital or long-term glasses is not suitable for double eyelid surgery. Due to exophthalmos, the effect may not be very good after surgery.

3. Distance between two eyes

According to the principle of "three courts and five eyes", a standard face width should be the length of five eyes, and the distance between two eyes should be equal to the length of one eye. People with moderate eye distance can achieve good results by double eyelid surgery. If the eye distance is too wide, people will appear stiff and unnatural; If the eye distance is too narrow, it will appear cramped.

4. Skin condition of eyes

The condition of the eye skin also affects the surgical effect. If the eye skin has good elasticity and less eye fat, the postoperative recovery will be fast and the effect will be natural; If the eyelid has excess fat, it should be removed at the same time as the operation, otherwise the eyelid will appear thick and the effect will not be natural; If the eyelids are obviously flabby, it will increase the difficulty of surgery. The double eyelids are affected by skin wrinkles, and the effect is difficult to guarantee.

5. Coordination of facial features

The coordination of the five facial features refers to the ratio of "three courtyards and five eyes", that is, the general standard ratio of the length and width of a person's face. If this ratio is not met, there will be a distance from the ideal face shape. Today, a more popular standard has emerged on the basis of "three courtyards and five eyes". All parts meet this standard, that is, beauty. The details are as follows: the width of eyes should be 3/10 of the width of the same horizontal face; The chin length shall be 1/5 of the face length; The distance from the center of the eyeball to the bottom of the eyebrows should be 1/10 of the length of the face; The eyeball should be 1/14 of the face length; The surface area of the nose should be less than 5/100 of the total face area; The ideal mouth width should be 1/2 of the width of the same horizontal face.
