Review of eye surgery from 3 years ago

About 3 years ago, I had double eyelid surgery at H Plastic Surgery Clinic in Busan. After consultations at a few places, I trusted that it was a place that made eyes look pretty and had double eyelid surgery there, and I ended up with double eyelids that looked natural and pretty to anyone. I liked them too, and they were natural-looking double eyelids to the point that people around me or people meeting me for the first time could not tell whether I had double eyelid surgery. Two years later, I woke up and the double eyelid on one eye had become two lines. At first, I thought maybe it was because I was tired from work and did not think much of it, but not long after, the other eye also became two lines. Should I go back to the place where I had it done and have surgery there? Or should I look for another place? I am considering revision surgery.
