[Double eyelid Burial] One side of double eyelid loosened after 7 years due to burial

I had eye correction because the muscle that opens one eye was weak, and it eventually resolved. When I first did it, I heard a lot of people around me say that it was very natural and not noticeable. But now, 7 years later, it has resolved. At that time, I was 70% on both sides. I gave it to them, but now I'm going around to get an estimate for one side, and they almost say that they recommend doing both because it's noticeable if you only do one side ㅠㅠ Those who have a thin line and have weak eye opening strength... I think you should consider that it may loosen later ㅠㅠ Reoperation is also stressful, eye correction Even though I received it, it is released ^.^.....
