3D Suture Technique (3D ST™)

3D ST™ is the latest, most innovative suture technique for double eyelid surgery that mimics the natural Asian eyelid fold in anatomy and functionality. 3D ST™ is performed exclusively by Dr. Kenneth Kim, innovator and patent holder of the 3D ST™.

Unlike the previous suture techniques, 3D™ allows for deeper crease formation as well as improved functionality of the eye muscle.

While surgeons could use previous suture techniques to control the height of the crease, height itself does not always provide the most natural and dynamic result that a patient desires. In addition, surgeons must consider the strength of the eye elevating muscle before performing the suture technique to determine whether a patient’s muscle is powerful enough to hold an extra fold. Otherwise, a weak eye elevating muscle cannot bear the weight of the extra fold, causing a shallow or loosening fold. Although patients may desire a suture technique for fast recovery and a natural looking crease, previous suture techniques are not advised for patients with ptosis. Unlike previous suture techniques, the 3D ST™ is innovative in that this technique can be performed for patients with mild ptosis. This technique is ideal for patients with the following indications:

  • Patients who have had prior double eyelid surgery and require a less invasive procedure to prevent additional scar tissue
  • Patients with mild to moderate ptosis
  • Patients with regional weakness in the eye muscles (i.e., eyelids that dip down either toward the nasal or the outer side of face)

Traditionally, surgeons performed ptosis correction procedures by opening eyelids anteriorly by making an incision directly on the eyelid, which allowed surgeons to only perform an incisional method for creating the double eyelid crease. Even though patients may have had ideal thickness and eyelid tissue composition for suture technique, they may have had ptosis that forced them to choose incisional technique. The recent advent of the 3D ST™ allows the surgeon to create double eyelid crease with suture method while also correcting ptosis (Refer to Ptosis Correction Surgery). 3D ST™ considers three significant factors in creating truly attractive, natural looking eyes: the shape of the eyelid curvature, the depth of the crease, and the fullness of the double eyelid crease. 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.
