First of all, double eyelid surgery is a minor operation, but it also needs certain conditions. For example, the size of the eyeball is 1. Eyes, some are high myopia or hyperthyroidism, and some are the most prominent beautiful eyeballs. This kind of eye skin is not obvious, not obvious, and there is too much fat. Not as good as you think. 2。 Eyelids are particularly relaxed, eyelids are general, and they are a little young. Even though the effect of total eyelid resection is certainly not as effective as that of young people, most of them can only choose total eyelid resection, and the surgical effect is not good. The effect of other methods has hardly changed. 3. the size of the eye crack; The eye fissure is particularly long, which is suitable for cosmetic double eyelid surgery, but it should not be too wide, because it is too wide to have a bad effect after surgery. It seems that the eyes with big eyes are round, and the big ones are definitely not good. On the contrary, the effect is not good and too narrow. It is too small. Article 4. Distance between eyes; If the distance between the eyes is too far and exceeds a certain limit, even if the double eyelids are not beautiful, some other plastic surgery should be done before the double eyelids are done, and double eyelid surgery will be done after other operations, and the effect will be very good.
