At present, there are many surgical methods for opening the corner of the eye in clinic: "V-Y" suture method, "Z" molding method and four-flap method. The former is suitable for mild epicanthus, while the latter is suitable for all kinds of epicanthus. No matter which method is used to open the corner of the eye, a certain scar will be left at the incision 3 ~ 6 months after operation. At present, the most widely used method is the modified transverse correction of epicanthus, which has good effect and no obvious trace after operation. It is an ideal epicanthus incision.

The price of minimally invasive canthotomy is closely related to many factors. Different conditions of different beauty seekers determine the price of canthus opening, and different surgical methods determine the price of canthus opening, so the price of minimally invasive canthus surgery ranges from several thousand yuan to ten thousand yuan.
