If you are ultra short on time an want to know at least something there are 2 GREAT books. Vaughn is actually the bomb also but to really read that book takes time (you could skim it quick but to get a lot out I don't think can be done quickly.) Blueprints makes a really good book that is also small enough that you can carry in your white coat during the rotation. It is actually very, very good. Also I would read all of Clinical Ophtho made ridiculously simple before you start partly because this is definately an acheivable goal and you at least will have a great grasp on myopia, hyperopia, and presbyopia. But it covers way more that that. Also its newest edition includes a CD which shows LASIK, LASEK, and cataract surgery. AND if that wasn't enough it includes tons of pics of eye disease (on the CD). There is absolutely no book for this amount of money (like 20 bucks) that can touch this much clinical info. Good luck I hope you do well. Don't get discouraged if you aren't really impressing anybody though, I think that it is very hard to do on an ophtho rotation just because the field is so specialized and most med schools provide almost zero training in eye disease.
