There are three main methods to make double eyelids: one is the traditional catgut embedding method; The second is the three-point tangent positioning method; The third method is full cutting and peeling. These three methods have their own advantages and disadvantages. The advantages of catgut embedding are less trauma and quick recovery. The most important thing is suitable for eyes with thin eyelids and good congenital conditions. The disadvantage is that the buried thread is easy to loose, and the eyeliner may be loose or inverted in the later period. Three-point incision positioning method is mainly aimed at cases with thin eyelids and good congenital conditions. Because it doesn't peel off, the eyelid with large skin volume may have entropion, which has the advantages of less trauma, faster recovery, more accurate positioning than embedding thread, and easy control of both sides width. The total excision method is to remove the redundant tissue in the case of more eyelids or more fat, so as to achieve the effect of more upturned eyelids and eyelashes. Most people with single eyelids and swollen thick eyes are most suitable to take full-cut peeling to achieve ideal results. The cost of surgery varies from institution to institution, which is about 5000- 10000.
