4This book is dedicated to my parents, Prof S Abraham and Ms Kamalam Abraham for making me what I am now.
It has been my ambition to write a book on cornea for postgraduate students in ophthalmology.
Cornea is important from patient viewpoint in that even minor affliction may result in gross defective vision, and from surgeon's point of view in that any corneal lesion requires immediate and proper attention. He also has to diagnose almost on the spot since the lesion is obvious and he is compelled to explain then and there itself what the problem is, the treatment and the prognosis. A retinal surgeon can buy time behind the veil of FFA and, during that time, can consult someone or some book. This is almost not possible for corneal surgeon.
So, for an ophthalmologist worth his qualification and experience it is mandatory that he knows corneal diseases well – even if he professes himself to be a retinal surgeon or a neuro ophthalmologist. He has to acquire this knowledge before finishes his academic training and steps into the wide world.
This book does not claim to be a complete treatise on cornea. Its aim is to teach the students pursuing the knowledge of ophthalmology the basis and, to some extent, details of diseases of cornea. I have studiously refrained from burdening the readers with minute details. If this aim is achieved, it will fulfill the purpose of the author in writing this book.
A feedback from teachers and students is most welcome, so that errors which might have sneaked in can be rectified in the next edition.
I am grateful to the Management of Vinayaka Missions for their help and encouragement. I am thankful to my wife, Leela, for bearing with me when I burnt my midnight candles, to my son Dr Marcus Abraham and to other colleagues who guided me in writing certain chapters. I am also thankful to Dr. Kalavathy of Trichy Joseph Eye Hospital for many excellent photos and to my computerists who put up with all my whims and vagaries.
