In this second installment of The Digital Manual of Ophthalmic Surgery and Theory we examine three pertinent modalities currently available to ophthalmic surgeons. Dr Kimberly Sippel and the corneal experts from Weill Cornell Medical College give an in-depth review of the Boston Keratoprosthesis. International experts on corneal tomography and ectasia, Dr Michael Belin and Dr Renato Ambrosio, Jr, highlight the use of Scheimpflug corneal analysis in the detection of corneal ectasia. Refractive cataract surgery experts Dr Gregory Parkhurst and Dr Stephen Slade discuss the new technology of femtosecond laser-assisted cataract surgery. Each subject is presented in an interactive format with embedded images, video, hyperlinks, and review questions. Residents, fellows, and experienced surgeons alike will benefit from the most up-to-date discussions available from a cohort of international experts.
