MS4 here, just about to graduate and start my prelim year next year before I start ophthalmology training (YEAH!!!). I've been shadowing several private practice ophthos around on my current rotation. We got to talking about where I'd like to practice, home vs. away, big vs. little, wife/kids/etc...and anyway I told them that I would like to go back home. There are currently 3 ophthalmologist in my home town of about 25k. My question is....what is the population size needed on average per ophthalmologist to have a sustainable practice? 10k, 15k, 30k???
