I had it done 2 years ago, and the eye-opening correction was really good. I had tri-white eyes and weak eyelid-opening strength, but it was fully corrected. (Mine was a really severe case definitely something that had to be done..) If you like dramatic eyes, it will probably suit you well. Before, my eyes were a bit long, but now they are round. It really feels like being reborn..
The downside is: The incision line for the double eyelids is visible. (It is not severe, but it does not look fully natural) I saw a lot of people saying the doctor is unfriendly, but from my perspective it was not bad. Still, I did think they had a very strong sense of pride. So maybe that is why people feel that way. They are not exactly warm and friendly lol
And if you look around, there are really a lot of complaints about the hospital being unfriendly lol But since there did not seem to be any broker involvement and they do not seem to do much management, that actually made me trust them more. There were more complaints about unfriendly behavior than about dissatisfaction with the surgery
