The curvature shape of the eyelid is crucial in altering the character of a person’s face, such as enhancing a sense of alertness or youth. The harmonizing depth of the crease is also important, since a shallow crease can appear too soft and unnoticeable while deeper depth appears harsh and unnatural. The fullness of the crease is a measure of how distended the skin appears within the crease. Attaining balance of the fullness is also crucial in creating a natural crease and bigger eyes.
These three factors have dramatic effects on the appearance of a patient, as any distortion in one of the factors can result in an unnatural eye appearance. 3D ST™ allows the surgeon to have control over all three factors, and it can also be used for revision procedures to achieve all three factors.
