I was in need of an eye doctor really bad on my trip when I got an infection. My boss told me the best thing to do was to go to an Apotheke and ask one of the pharmacists. Unlike in the States, German pharmacists have a lot of general knowledge of medical conditions, allowing them to aid you in the hunt for the right medicine AND the right physician. Sure enough, the pharmacist recommended an optician nearby for my eye infection and saved the day.
