Book Description
The cornea is a vital part of the eye that plays a crucial role in our vision. As students interested in the field of ophthalmology, it is essential to understand the significance of the cornea and its role in maintaining clear and healthy eyesight. The cornea is the transparent, dome-shaped front surface of the eye, covering the iris, pupil, and anterior chamber. It acts as a protective barrier, shielding the eye from dust, debris, and harmful UV rays. Additionally, the cornea plays a significant role in focusing light onto the retina, allowing us to see objects clearly. One of the primary functions of the cornea is to refract light. When light enters the eye, it is bent or refracted by the cornea. This refraction helps to focus the light rays precisely onto the retina, which is responsible for converting the light into electrical signals that are interpreted by the brain as images. Therefore, any irregularities or abnormalities in the shape or thickness of the cornea can lead to vision problems such as nearsightedness, farsightedness, astigmatism, or even blurred vision. Maintaining the health of the cornea is of utmost importance. Various external factors can affect the cornea, including injuries, infections, and diseases. Students studying ophthalmology must understand the various corneal diseases and conditions that can impact vision. Some common corneal conditions include corneal ulcers, dry eye syndrome, keratitis, and corneal dystrophies. Recognizing the symptoms and understanding the treatment options for these conditions is vital in providing appropriate care to patients. Furthermore, the cornea is a unique tissue that has the ability to regenerate. This property makes corneal transplants possible, where a damaged or diseased cornea can be replaced with a healthy donor cornea. Learning about corneal transplantation and the factors that affect its success is crucial for students interested in ophthalmology.

Book Description
The field of cornea has seen tremendous advances over the last 40 years—this uniquely comprehensive book will discuss the history of these advances, current best practices in important diseases of the cornea and ocular surface, and examine future directions in diagnosis and management. Written by leading experts, many of whom trained under Claes Henrik Dohlman, MD, PhD, whose influence and many invaluable contributions have defined and shaped the field of cornea, each chapter will reflect the state of the art in the various aspects of cornea. Foundations of Corneal Disease: Past, Present, and Future contains six different sections, opening with an introduction which delves into the evolution of subspecialty training in cornea, and provides a historical perspective of our understanding of ocular surface disease. Section Two addresses perspectives on important corneal and external diseases including infectious keratitis, dry eye, and herpes simplex. Section Three and Section Four address surgery and surgical alternatives, and frontiers in corneal research. Section Six closes this book with a discussion of special topics: imaging the cornea, corneal blindness, eye banking, and clinical trials in dry eye, and explores future directions in this fast-paced field. Foundations of Corneal Disease: Past, Present, and Future contains is an ideal guide for corneal specialists, ophthalmology residents and fellows planning to enter cornea, corneal scientists, and to those in ophthalmology and visual science interested in a comprehensive resource on cornea and the history of this field.

Book Description
"Essentials in Ophthalmology" is a new review series covering all of ophthalmology categorized in eight subspecialties. It will be published quarterly, thus each subspecialty will be reviewed biannually. Given the multiplicity of medical publications already available, why is a new series needed? Consider that the half-life of medical knowledge is estimated to be around 5 years. Moreover, it can be as long as 8 years between the first description of a medical innovation in a peer-reviewed scientific journal and publication in a medical textbook. A series that narrows this time span between journal and textbook would provide a more rapid and efficient transfer of medical knowledge into clinical practice, and enhance care of our patients.

Book Description
This outstanding volume in the Essentials in Ophthalmology series presents recent developments in the diagnosis and treatment of corneal disease. Its intention is not to replace the relevant textbooks, but to serve as a bridge between primary and tertiary literature. The superbly structured volume covers a dizzying array of topics including Herpes simplex keratitis; amniotic membrane transplantation for the treatment of corneal ulceration in infectious keratitis; and Chlamydial infection, all three of which are hugely relevant today. All the topics have direct clinical importance and will not only keep ophthalmologists up to date, but will inform them of how to treat their cornea patients with optimal diagnostic and therapeutic procedures.

Book Description
This comprehensive volume presents data describing the role of oxidative stress in anterior eye disease. The content is divided into three logical parts: basic science of the cornea, basic science of the lens, and clinical practices. The first two parts include eighteen chapters that discuss topics ranging from oxidative stress and dry eye disease, endogenous protection of corneal cells against oxidative damage, the therapeutic potential of corneal stem cells, etiology of cataracts and preventive measures, corneal degeneration through oxidative stress and cataract formation, and function and dysregulation of ion channels and transporters in the ocular lens, among others. The concluding part is comprised of four chapters devoted to advancements in corneal surgery, cataract and diabetic retinopathy, the clinical treatment of cataracts including traumatic cataracts, and cataracts in the pediatric age group. Studies on the Cornea and Lens is an essential addition to the library or department of physicians and researchers who treat or research these ocular conditions, particularly cataracts. It is also a key resource for cell biologists studying oxidative stress. This book is an authoritative contribution to Springer’s Oxidative Stress in Applied Basic Research and Clinical Practice series.
