What should an international patient prepare before traveling?

First, obtain a medical visa (S2 or M visa) by providing a hospital invitation letter and treatment plan. Arrange a certified medical interpreter if you do not speak Mandarin, as many hospital staff have limited English. Bring all previous eye exam records, including refraction tests and photos showing eye alignment. Plan for a minimum 1-week stay, and confirm with the hospital whether follow-up care can be done remotely via telemedicine or if you need to return. Also, purchase travel health insurance covering elective surgery.
