1) Eyes with more fat: The eyelids are cut open and the appropriate amount of thick fat layer and muscle is removed to make the eyelids thinner. 2) Eyes with thin and large eyelids: their surgical results are the best. Beautiful double eyelids can also be made with the buried line method. 3) In the case of one eye with double eyelids: it is only when both eyes are operated on at the same time that it becomes more natural and reduces the risk of asymmetry. In this case, the eyelid on the side with double eyelids is made slightly larger than the original one, while the other side is made to look like the opposite side of the eye that was operated on. The eyes are most beautiful when they are symmetrical. 4) Eyes of different sizes: While the difference in the size of the two eyes themselves cannot be completely corrected, you can try to make the difference between the two eyes appear less obvious through double eyelid surgery. 5) Eyes with wide spacing between the eyes.
