The field of cornea and external diseases has changed dramatically in the last decade. From the new technology that we as ophthalmologists have to help us diagnose ocular surface disease, infectious keratitis, and ocular allergies to the new treatment options for these entities, we have many new tools to help us and to help our patients. Techniques and standards of care in surgery have even changed to the point that the same patient who would have walked into our office 10 years ago and would be offered the then standard penetrating keratoplasty for any corneal disorder could now be offered something different and better: anterior lamellar keratoplasty, endothelial keratoplasty, keratoprosthesis, or even laser-assisted penetrating keratoplasty. Furthermore, we can even better help patients avoid the need for surgery, with advances in contact lens technology and collagen cross-linking. Finally, as our surgical repertoire for corneal procedures has increased, the role of the eye bank in facilitating our procedures and in some cases making it possible at all to do our procedures has increased exponentially.
This book aims to present the latest information in the diagnosis and management of the spectrum of medical and surgical corneal diseases, with special focus on new technology. Each chapter is authored by leading authorities in that area, who share my passion for providing the very best and the most cutting-edge care for our patients.
I would like to express my sincere appreciation to these authors for lending us their expertise and providing their valuable contributions to this book. I would also like to thank Springer Publishing and their staff for making this book possible. Finally, and most importantly, I would like to thank my family for their unconditional love and support: my wonderful wife Linda; our three beautiful children Cassie, Dailen, and Garin; my loving parents Arco and Er-An; and my dear sister Eileen.
