I had a sub-brow lift and buried-incision double eyelid surgery. Asymmetry was visible from the beginning, but on the day the stitches were removed after one week, they had a 1-minute consultation saying the surgery went well and only kept saying the lines would match. In the end, after 6 months, I received a partial AS revision (raising one line and raising the end line on the other side).
Even after the AS revision, it did not improve and the asymmetry was severe (not just my personal opinion; other hospitals also noted asymmetry during consultations), but during photo consultation they flatly said there was no problem. My AS was refused.
It was a bit strange that the director discussed how to set the double eyelid line with the consultant. There were many foreigners, and perhaps because of the YouTube effect, the hospital was chaotic, like a marketplace. They point out what went wrong at other hospitals well, but do not acknowledge the results of their own surgery. After stitch removal, there was no follow-up appointment and no aftercare at all. If a problem occurs, the system is that you have to speak with the consultant. The hospital fee was also expensive, and it is a place I never want to visit again.
