Asymmetrical results - the right eyelid was visibly larger and wider

Dr. Wang is incompetent and irresponsible. I had a simple eyelid surgery by Dr. Wang, and I look worst after the procedure. As the picture shown, not only my left eyelid fold is barely visible, and the eyelid is obviously uneven. I feel devastated and hide my eyes behind the glasses after the procedure. However, after a follow-up with Dr. Wang regarding this obvious asymmetric of my eyelids, Dr. Wang does not want to take any responsibility for his ridiculous screw-ups. Instead, he blames the eyelid folds unevenness on my facial asymmetric and eyebrow height difference. Dr. Wang also wants to charge me $500 to correct his mistake. I don’t agree that I am the one who should take the full financial responsibility to correct the left eyelid. My eyelids were uneven immediately after the procedure, and the right eyelid was more swollen and bigger compared to my left one. Dr. Wang said that it’s because my right eyelid was “more fatty”. However, when the swelling subsides, it was so obvious that the eyelids were asymmetrical. The right eyelid was visibly larger and wider. I emailed Dr. Wang’s office, and Michelle told me the asymmetric will get better with time. It’s been more than a year after the procedure and I don’t see any improvement. Dr. Wang, what is your liability for making a mistake?
