It's not a hospital, and the authority is hard to say, but now I basically go to Tianjin Eye Hospital, which is basically not recommended by medical university. The year before last, I wanted to see my eyes. Tianjin local students specifically told me not to go to the eye hospital of medical university. The first one should be enough. As for the appointment, I haven't made an appointment yet. I don't know, but if you check their phone numbers, you should be able to make an appointment by phone.
