To recapitulate the considerations that have led to the publication of the 3rd edition of Textbook on Corneal Topography Including Pentacam and Anterior Segment OCT are that the manual is prepared with the idea that revisions must be made periodically in order to have an available text that represents the status and details of corneal topography. The book provides a detailed text to assist with the interpretation and diagnosis of corneal surface disorders and also provides an up-to-date reference book for all the ophthalmologists.
