The fat backfilling of externally incised eye bags can usually last for about five years. Generally speaking, with the use of external incision fat backfill, suspension and fixation of the orbital septal fascia, the results can be relatively good, and the duration of maintenance is about five years, but it also depends on the individual’s physical condition, as well as the degree of maintenance of the local skin around the eyes, the patient’s routine, and so on. The incision of fat bags under the eyes will leave a scar in the lower eyelid area, which may cause asymmetry of the lower eyelid incision on both sides after the operation, and there may also be scarring. In the early stage of removing the stitches, it may be necessary to use anti-scarring medication to minimize scarring, which may also cause bilateral asymmetry, and require standardized treatment under the guidance of a doctor.
