As a degenerative disorder of the eye, keratoconus can cause substantial distortion of vision, with multiple images, streaking, and sensitivity to light all reported by patients. Keratoconus: Recent Advances in Diagnosis and Treatment updates ophthalmologists about the innovations that have occurred within the last decade, discussing the diagnostic imaging techniques that have been developed for keratoconus diagnosis, understanding of how examination techniques are related to the evolution of keratoconus, and how to indicate the different therapeutic tools that have been created for keratoconus over the last several years. Additionally, fundamentals for new diagnostic elements, based on the mathematical, physical and biomechanical data are analyzed in depth for a better understanding of the essential diagnostic steps for the clinician to guide patients towards the most adequate therapeutic tool in the case. Modern keratoplasty techniques, assisted by femtosecond lasers or other devices, are also covered and these techniques, along with the emerging conservative treatments, have added to more precise control of the evolution of the disease.

In recent years, keratoconus and keratoectasia have become increasingly important ophthalmic diseases due to the increasing number of keratorefractive surgeries being performed, the subsequent rising number of complications, and the availability of new treatment modalities for keratoconus and keratoectasia other than corneal transplantation. For both the genetic form of the disease (keratoconus) and the acquired form (keratoectasia), new modalities of diagnosis and treatment have enabled physicians to manage and treat these diseases earlier and more effectively, which can delay or even prevent major surgeries. Keratoconus and Keratoectasia: Prevention, Diagnosis, and Treatment by Dr. Ming Wang, along with over 40 contributors, represents the first state-of-the-art, comprehensive synthesis of the current understanding of the etiology, prevention, diagnosis, and treatment of keratoconus and keratoectasia. Diagnostic Modalities Include: - Topographic diagnosis – placido disc and elevational mapping analysis - Posterior corneal analysis, three-point touch method and FFKC criteria 2009 - Corneal pachymetry mapping and progression analysis - Statistical analysis packages for KC - New imaging technologies for the cornea including OCT - Topographic corneal irregularity analysis for premium IOLs - Measuring corneal strength – corneal hysteresis - Corneal epithelial mapping with ultrasound biomicroscopy - Wavefront analysis in keratoconus - Infrared light image screening – a new screening tool for keratoconus Treatments Include: - Non-surgical treatment with contact lenses - Ocular surface treatment - Lamellar and penetrating keratoplasty - Excimer laser surface treatment - Topography-guided excimer laser treatment - Wavefront-guided excimer laser treatment - Intacs intracorneal segment - UV-cross linking - Combination treatment of cross-linking, Intacs and excimer laser ablation - Future treatment Keratoconus and Keratoectasia: Prevention, Diagnosis, and Treatment is a concise, well-illustrated and clinically indispensable guide for treating these two important ophthalmic diseases and is a must-have for all ophthalmologists, optometrists, residents, fellows, and medical students.

This book presents new technologies which are available now for the rehabilitation of visual acuity in patients suffering from keratoconusand for arresting the progression of this frustrating disease. All these current treatment options in differing combinations aim to improve the quality of life of the patients and although successful, they are causing confusion for the ophthalmologists; what procedure to do and when? How to perform? Which combination of treatments to choose? Controversies in the Management of Keratoconusprovidesthe widely used treatment options for keratoconus including collagen corneal cross –linking (CXL) covering all the available techniques, intrastromal corneal ring segments (ICRS) , phakic intra-ocular lenses (IOLs), photorefractive keratectomy (PRK) combined or not with CXL penetrating keratoplasty (PK) and deep anterior lamellar keratoplasty ( DALK). Each treatment is addressed by more than one author with different points of view in order to present the various approaches, the logic behind them and the most relevant clinical data available.A chapter by the editor tries to put some light on how to navigate among these controversies. This book will be of interest to trainees as well as the specialized ophthalmologists.

Keratoconus is a condition in which the cornea assumes a conical shape due to thinning and protrusion. The condition is usually bilateral and asymmetric. Refractive error will constantly change and as it progresses it impairs vision. Patients will have symptoms of visual blur, distortion, glare, photophobia, ocular irritation, pain, red eyes, tearing and monocular diplopia (also known as ghost images). Irregular scissor motion on retiniscopy reflex, abnormal ophthalmoscopy reflex, egg-shape mires on keratometry, Vogt's striae, Fleisher ring, Munson sign and hydrops are the characteristic signs of keratoconus. The etiology is unknown. Atopic diseases, wearing hard contact lenses and heredity have been mentioned as the cause. Among the management options are spectacle correction, soft contact lenses, hard contact lenses, combinations of soft-hard contact lenses, and as last option, surgical procedures. Management depends on the severity and the classification of the cone.

This book, designed for ophthalmologists and particularly for refractive surgeons, aims to develop practical and clinical skills in readers so that they are able to make the right decisions in managing keratoconus. There are four main chapters. The first is devoted to diagnosis and describes the clinical signs, the appearances on microscopy, and the significance of corneal hysteresis and corneal topography. Classifications and patterns of keratoconus are then presented, and the author offers his own new classification of topographic patterns. The third chapter addresses the management of the disease in detail. Both non-interventional and interventional approaches are discussed with due attention to contraindications and complications. In addition, a novel classification of management parameters is suggested, and a systematic approach to management, formulated. In the final chapter this approach is applied to nine cases that serve as clinical examples.

Keratoconus is degeneration of the structure of the cornea. The cornea is the clear tissue covering the front of the eye. In keratoconus, the shape of the cornea slowly changes from round to conical (PubMed Health). In the early stages, keratoconus can be corrected with the use of lenses, but in the later stages, surgery is the only option. Holcomb C3-R® is a non-surgical technique that involves placing drops of the vitamin Riboflavin into the eye and using a UV light to activate them. The drops strengthen the fibres of the cornea and over time, preserve sight (American Keratoconus Association). This book is a concise guide to the technique of Holcomb C3-R® to treat keratoconus. Authored by the inventor of the procedure, Brian S Boxer Wachler, the text is based on his first hand clinical experience and explains the history and basic science of cross linking, the development and naming of the technique, its uses and complications, and first patient results. Key points Concise guide to technique of Holcomb C3-R® to treat keratoconus Authored by inventor of the technique and based on clinical experience Includes more than 60 full colour images and illustrations

Abstract: Advances in anterior segment imaging have enhanced our ability to detect keratoconus in its early stages and characterize the pathologic changes that occur. Computerized corneal tomography has elucidated the alterations in shape of the anterior and posterior corneal surfaces and alterations in thickness as the disease progresses. Automated screening indices such as the keratoconus screening index were developed to assist in detecting keratoconus in suspicious cases. In vivo assessment of keratoconic corneas has revealed that compromised corneal biomechanics can now be measured clinically. Optical coherence tomography has demonstrated alterations in corneal epithelial thickness and distribution in keratoconus, has a role in assessing Descemet's membrane detachment in acute corneal hydrops (ACH) and the depth of the demarcation line following corneal collagen cross‐linking. In vivo confocal microscopy has exhibited cellular changes that occur in keratoconus and provided insight into cellular events that may be related to the development of neovascularization in ACH.
