Language barrier at Korean plastic surgery clinics - should I worry?

I do not speak Korean and I am worried about communication during my plastic surgery consultation and surgery. How do Korean clinics handle foreign patients who do not speak Korean? Do most clinics have English-speaking staff or interpreters? Is it common for the actual surgeon to speak English? I am concerned about accurately communicating what I want and understanding post-operative instructions. For those who have had surgery in Korea without speaking Korean, how did you manage? Should I hire my own interpreter? Any tips for clear communication about aesthetic goals?
