Dedication, First Edition

This book is dedicated to my beloved parents, Henry and Sheila.

Acknowledgments, Second Edition

My family continues to put up with my workaholic tendencies, and for that I am grateful. To all the ingenious people who find ways to improve on technology in the ophthalmic field, I truly admire you. There are too many to name, and I would not even know who many are, but I am glad these people exist so that we can take better care of our patients and help countless people see better than ever thought possible.

Acknowledgments, First Edition

It is a pleasure to acknowledge the people who have made a contribution to my ability to write this book. First, without the generosity of Dr. Howard Gimbel, I would not have had an opportunity to work in ophthalmology. Judy Gimbel encouraged me to write The Ophthalmic Assisting Guide, followed several years later by the second edition. I am indebted to my family—my wife, Sheila, and daughters, Bridgette and Meagan—who have been supportive during all the days and nights I have spent writing. And, of course, my appreciation to Jan Ledford, the editor of this wonderful series, who has been kindly critiquing my work.

About the Author

Al Lens began his ophthalmic career in 1986 at the Gimbel Eye Centre in Calgary, Alberta, Canada. His keen interest in learning and teaching put him in the position of training ophthalmic assistants. After writing The Ophthalmic Assistant Guide, Al began lecturing across North America at various conferences. His teaching has taken him as far away as Saudi Arabia. He is author of LASIK for Technicians and coauthor of Ocular Anatomy and Physiology and Cataracts and Glaucoma. The latter 2 publications are part of The Basic Bookshelf for Eyecare Professionals Series.
