The BCSC books have lots of important knowledge but are unfortunately very dry and poorly written (due to its committee-based approach). Reading them are important for the OKAPs and boards, but one way to more efficiently increase your study yield is to look up the subject matter online. There are many more useful compendiums (such as eyewiki) that present the information in a dense but efficient manner.
Also, when reading about pathology, don't neglect to look at lots of pictures - an atlas or google/bing image search even. Ophthalmology is similar to dermatology in that we are in a visually-dependent field of medicine, so constant repetition of seeing things help.
