i've heard similar things about northwestern from faculty at my school. program has been in a slump for some time, and they are having trouble with surgical volume - residents are sent on rotation to louisiana to boost surgical numbers. reputation-wise its not a powerhouse, not the best in chicago by any means (for ophthalmology, that is). Duke has a strong reputation (top tier) and superstar faculty in several departments (cornea, retina in particular). downside: location. do your research and choose wisely.
