Cosmetic surgery abroad – rhinoplasty/nose job in Iran?

I am flying out to Iran next week hoping to have my nose done there. Got a few surgeons lined up and then if I feel comfortable i’m going ahead with it! Has anyone here been abroad for cosmetic surgery, especially rhinoplasty? If so how was it? What are the risks and things I need to know? I am staying with family there so I will be taken care of, etc… just scared as it is a foreign country. I live in the UK where it is too expensive. It costs half the price or even less in Iran and they perform thousands of rhinoplasty operations there each year so it is a good choice?
