I highly recommend the book clinical ophtho made ridiculously simple. The book even includes a great CD with videos of cataract surgery and essentially a small ophthalmology atlas on it. And if that isn't good enough the book is only like 20 bucks. I would never buy basic ophthalmology as basically every program I did an away rotation at tried to give me the book to read and it will have no value to you when you go into ophtho. However, it is a great book that you should read, but in my opinion not worth your student loan cash. Good luck this is an awesome field, I have no regrets.
