In recent years, keratoconus and keratoectasia have become increasingly important ophthalmic diseases due to the increasing number of keratorefractive surgeries being performed, the subsequent rising number of complications, and the availability of new treatment modalities for keratoconus and keratoectasia other than corneal transplantation. Keratoconus and Keratoectasia by Dr. Ming Wang, along with over 40 contributors, represents the first state-of-the-art, comprehensive synthesis of the current understanding of the etiology, prevention, diagnosis, and treatment of keratoconus and keratoectasia. It is a concise, well-illustrated and clinically indispensable guide for treating these two important ophthalmic diseases and is a must-have for all ophthalmologists, optometrists, residents, fellows, and medical students.
