doheny....
Positives: beautiful location, great autonomy at LA county 1 and 3rd years. Good volume (~125-50 phacos). Big name faculty (esp retina), residents seem to get great fellowships. I think you will be well trained and extremely efficient as a graduate from there. The Chair seems to be very supportive, approachable, and down to earth.
Negatives: the 1st, 3rd years are worked to the bone at County. Many looked dog-tired. Not in of itself, bad, but there is very little ancillary support (techs) at County, and I'm not sure how much you are taught by the bigwig Doheny faculty except for the second year. At county, it looks like you have huge volume immediately, like the first month of 1st year, and there is not that much teaching. Guidance is available from seniors , but they are also busy as 3rd years. I think the County attendings are volunteers.
Misc: one odd thing seems to be the Assistant Chief of Service position. Usually a 1-2 yr position at most progs, but the current ACS has been there for 5 years, and looks to be there indefinitely. If one has questions, you ask your senior, if not ask ACS, if not then an attending. The ACS is mostly at County (2/3 of your time as a resident) has a big role in resident teaching. However the relationship of the ACS with some of the residents seems uneasy. Since you're spending most of your time at County, I think it is key to be ok with working independently (know how do to a through exam) immediately when you start, be able to deal with county staff and mentality, and to get along well with the ACS.
In general, I always wonder what a good balance is on: great autonomy but little supervision (county, va, etc) vs. less autonomy but good teaching (univ hospital etc.)
