The very act of educating our colleagues is laudatory by nature. This is the goal of most textbooks. Specifically, in this text, Dr Amar Agarwal, known as both an impressive educator and author, has assembled a group of experts in field of contact lens analysis, design and fitting. With their intelligent support, he has attempted to provide us with an in-depth analysis of the theory, science and art, of contact lens fitting.
Expert authors, in the subjects of physiology, and pathophysiology of the cornea and tear film, provide a basic understanding of the environment for successful contact lens fitting.
Building upon these basic scientific principles, specific areas of contact lens applications are then sorted out. The carefully chosen chapter subjects deal with specific problem areas, which are often encountered, in the clinical setting. With a problem-solving methodology in mind, tactics of fitting contact lenses are then discussed.
Each chapter is practical, instructive and, above all, valuable in a rational sense. The “step by step” approach adopted by all the authors adds a unique, physician-orientated methodology, which is easily appreciated by the reader.
The goal of providing one textbook, which can serve as a reference for practicing ophthalmologists to perfect their ability to use contact lenses for a multitude of therapeutic applications, is skillfully achieved.

13Preface
Contact lenses form an integral part of practice even in this age of lasers, phakic IOLs, intrastromal rings etc and contrary to the common view, fitting of contact lens and its complications is not out of the preview of the practicing ophthalmologist.
For this purpose, we have tried to bring out a very comprehensive at the same time informative book about contact lenses by a group of experts in the field. Such a book is incomplete without the basic knowledge of physiology and pathophysiology of the cornea and tear film. The first section covers this area, while the second section goes into the details of the various kinds of lenses and the methodology of fitting. The chapter on contact lenses for children will be especially useful for the ophthalmologists. The third section covers all the other msicellaneous topics.
This book will be useful for all from post graduates to leading ophthalmologists. It especially serves as a quick reference to contact lens fittings and its associated problems by delving into how to deal with them.
