Of course, double eyelid surgery can only make one eye, but in order to make both eyes look the same, the requirements for doctors are very high. Some people just have double eyelids and single eyelids. As for your situation, you still have to talk to the doctor face to face to confirm the situation.
I don't know where you are. If you are in Hangzhou, I'll recommend an effective doctor in double eyelid surgery. My friend's former doctor, Lv Min, the president of Hangzhou Times Hospital, is very nice and easy to communicate with. You can go to Times Hospital.
