Preface

The New Orleans Academy of Ophthalmology proudly presented its 51st Annual Symposium from February 22nd to February 24th, 2002. Entitled “Wavefront and Emerging Refractive Technologies,” it proved to be an exciting update on the principles of wavefront technology, as well as a glimpse into the future of this exploding field.

Dr. Marguerite McDonald is to be thanked for heading up the program committee that organized an excellent meeting. Amber Howell, executive director of the academy, also deserves recognition for working to make the meeting the success that it was. Dr. George Ellis, Jr., president during the meeting, and the members of the executive committee all also deserve thanks.

The internationally recognized faculty assembled by Dr. McDonald generously shared their experience and techniques with a large audience, and then expanded on their presentations in the many round tables and question and answer sessions. All of those sessions have been transcribed and included in the following text, since they are part of the magical educational experience that the New Orleans Academy meeting offers.

Editing this text has been both a challenge and an honor. I am deeply grateful to the New Orleans Academy of Ophthalmology for allowing me to learn from its meetings for so many years. This volume is but a small token of the gratitude owed to this organization for the knowledge it has imparted to me, and to many others during its 51 years.

The publication of this book would not have been possible without the generous support of the Eye, Ear, Nose & Throat Foundation. On behalf of the members of the New Orleans Academy of Ophthalmology, I thank the foundation for allowing our educational mission to continue.

Jill B. Koury, M.D.
