Is it just experience? I feel like I have trouble when the staff doctors grill me on stuff I should know. When I'm actually with a patient, I often times don't ask myself why a patient is giving me a certain response and when I get done talking with the staff I'm like, "Of course! That's why I couldn't refract that patient 20/20" or what ever. Any tips on "troubleshooting" abnormal patients/ atypical cases you've never dealt with before? General rules of thumb for tricky cases?
