I understand non-incisional double eyelid surgery can become undone after a couple years. But when the thread loosens, will the lid stay with the new crease where the thread was or will it go back to how it was before surgery? 

I was wondering because when you use double eyelid tape/glue for a while, usually a permanent crease is created. So if the thread has been there for years holding up the eyelid, I would assume that the crease would stay after the thread loosens. Or am I wrong? 

Not sure if anybody knows what I'm talking about but it's just something I've been curious about 🤔
