Astigmatism means the eye is shaped like a rugby ball so light is focused at more than one place in the eye. It is associated with short or long sightedness and can cause blurry vision, headaches and eye strain. Astigmatism is usually corrected with glasses or contact lenses. This book is a complete guide to the surgical management of astigmatism. Based on scientific evidence and practice, the text covers numerous diagnostic and treatment techniques for both regular and irregular astigmatism, including laser surgery and incisional and intraocular lenses. Each procedure is explained in detail describing new diagnostic technologies, patient selection, methods and limitations across applications. Authored by an internationally recognised team of experts, the comprehensive text is further enhanced by more than 350 clinical photographs, diagrams and figures. Key points Complete guide to surgical management of astigmatism Covers techniques for both regular and irregular astigmatism including laser surgery Internationally recognised team of expert authors Highly illustrated with clinical photographs, diagrams and figures

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.

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.

This comprehensive 2nd edition will build on the highly successful first edition, providing an updated global perspective of the fundamentals of multifocal intraocular lenses. The varying outcomes, limitations, and the neuroadaptation process necessary for an adequate clinical success are thoroughly discussed, along with an overview of the different types of multifocal lenses, including the recently developed extended depth of focus lenses. Multifocal Intraocular Lenses: The Art and the Practice, 2nd edition opens with an introduction that will delve into current technological offerings for the correction of pseudophakic presbyopia, as well as the opportunity for refractive lens exchange in advanced presbyopic ages and the opportunity to use these lenses. The first section will include the historical background and clinical indications, while section two addresses the varying types and models of lenses currently available, including important clinical and technological highlights. Section three and four will follow, and provide an extended look at the Zeiss and Alcon Family Multifocal IOL's. Section five will delve into extended depth of field lenses, and will contain an introduction about the concept, different models and the evidence available about their outcomes. Section six concludes the book, closely examining accommodative intraocular lenses, and a full update will be provided on these lenses, the failures of the past and the hopes for the future. Multifocal Intraocular Lenses: The Art and the Practice, 2nd edition is a thorough, resource for the practical ophthalmologist and ophthalmic surgeon interested in learning more about intraocular lenses, identifying the best technologies and lenses for the benefit of their patients.

Phakic IOLs (intraocular lenses) are surgically implanted lenses used for the permanent correction of common vision errors such as myopia (short-sightedness). These implants, which resemble contact lenses, are placed either between the cornea (the clear lens in front of the eye) and the iris (the coloured part of the eye), or just behind the iris. This second edition provides a comprehensive review of the technology and clinical indication of phakic IOLs, their contraindications, how to handle surgical complications and practical issues in their use in refractive surgery. Divided into two parts, the first section discusses the basic principles of refractive surgery with phakic IOLs and the second part examines their implantation including for astigmatism correction, combined and additive procedures and new trends. Key Points Comprehensive review of technology and clinical indication of refractive surgery with phakic IOLs Examines basic principles and implantation techniques Authored by highly experienced ophthalmic specialists in Europe and the USA First edition published in 2003
