Double Suture Technique (DST) - Permanent?

It is possible that your sutures are still holding or you developed scaring in the eyelid tissue that has preserved the effect or the sutures.  It is unusual to want to have the crease height changed to be higher as this moves an Asian eyelid to a more Western type of upper eyelid.  This change is generally undesirable.  However, it may be that what you are describing is the desire to have more upper eyelid platform expose.  The platform show is determined by how much skin exists above the crease.  A personal assessment is needed to determine precisely what you are looking for and how to accomplish it.

Ten years would be considered a very good outcome from a suture technique. You will more likely want surgery to remove excess skin or other aging-related process than from fold failure. I would be very satisfied to have a 10year + result from DST.

The suture technique can be long lasting. For most patients, the suture stays in place creating the crease and there is some scar formation, as well. However, as a patient ages, the eyelid skin changes along with the brow and soft tissue around the orbit. Because of the changes associated with aging, namely excess tissue, the creases may not be as prominent. A secondary blepharoplasty and even brow lift may be necessary at some point.
