This question book used to be the standard one that every Ophthalmology resident and/or fellow bought to prepare for his or her OKAPs and Written Board examinations. Though not bad, the questions are somewhat outdated and there are many typos littered throughout the book. I prefer to use online questions "books" such as ophthoquestions.com and occasionally even the AAO's ProVision service. I just don't think this book is worth $100 anymore.
