Preface

In the age of instantaneous electronic information, a bound textbook may seem to some, perhaps, anachronistic. We, and even more so, our residents and fellows are accustomed to finding quick facts and lengthy lists of citations with but a few key strokes at the computer. The time spent rifling through the pages of journals in a library or working one's way through a hard copy text is, for better or worse, diminishing in favor of the agility of the computer – ever faster, ever smaller, and ever more convenient. Indeed, there are some advantages to modern day electronic texts – universal access in spite of time of day or location, portability, rapidity of information access, and the ability to do complex Boolean searches in moments. Such features save hours of time. For these very reasons, this edition is made available in an electronic format as well as the print version.

At the same time, a multi-authored text which has been forged through the process of gathering the best minds in the field, written and rewritten through a laborious and meticulous editing process, and presented as a comprehensive and authoritative source that can be turned to repeatedly is highly desirable as a bound document – codifying the current state of our knowledge in one place.

The practice of our subspecialty in ophthalmology is more diversified than ever before. The proliferation of new surgical procedures targeted to specific corneal abnormalities, a variety of new diagnostic testing capabilities, and a dramatic broadening of our understanding of the pathophysiology of the cornea and ocular surface have revolutionized what we know about the remarkable structure through which we view the world. We hope that this book will continue to serve as a useful tool to all students and practitioners in our field, both in print and electronic forms.
