The difference between a scalloped eyelid and a parallel type of eyelid lies in the area of the corner of the eye, where the extension of the eyelid arc extends out from the corner of the eye, or over the head of the eye. If both sides of the eye are opened, after the eye opening is done, both will be parallel type double eyelids. If there is one side of the corner of the eye and one side did not open the corner of the eye, it may be that one side is fan-shaped and the other side is parallel double eyelids, or do double eyelid surgery, one side of the inner double eyelids of the corner of the eye position is low, later you can communicate with the doctor in charge of the repair. The corners of the eyes on both sides of each person are not the same, and can only be approximated, it is impossible to be completely equal, after doing double eyelid, but also need to accept the localization of slightly different.
