Book Description
Since the advent of keratorefractive surgery and its rising popularity, irregular astigmatism has become an increasingly important issue for ophthalmologists and optometrists. Despite the success of LASIK and PRK, there are more and more patients experiencing visual quality problems due to the non-physiological modification of the corneal structure. Among these complications, irregular astigmatism is perhaps the most difficult to treat. Every physician who performs keratorefractive surgery understands that in reducing a patient.s refractive error, there is a possibility of creating irreversible effects on visual quality. This text is intended to help prevent and reduce the iatrogenic creation of irregular astigmatism, as well as provide effective treatment when postoperative complications do arise. With the maturation of keratorefractive technology in recent years, effective treatment for iatrogenic irregular astigmatism is quickly developing. It provides everything refractive surgeons, ophthalmologists, and optometrists need to know about this important topic.

Book Description
This book explores the development, optics and physiology of astigmatism and places this knowledge in the context of modern management of this aspect of refractive error. It is written by, and aimed at, the astigmatism practitioner to assist in understanding astigmatism and its amelioration by optical and surgical techniques. It also addresses the integration of astigmatism management into the surgical approach to cataract and corneal disease including corneal transplantation.

Book Description
Astigmatism is an optical aberration characterized by rays propagating into two perpendicular planes focusing at different distances, thus providing two different foci delimiting an intermediate area of focus called the Conoid of Sturm. This book discusses the types, diagnosis and treatment options of astigmatism. The topics include management of astigmatism in patients after a corneal transplant; power vectors; toric intraocular lenses for the correction of astigmatism during cataract surgery; irregular astigmatism management; and a comprehensive overview of preexisting astigmatism during phacoemulsification.

Book Description
This book reviews the surgical techniques currently employed for the management of astigmatism, with the aim of providing a clear, comprehensive, step-by-step guide that will help practitioners to optimize outcomes. The book is divided into two sections covering the cutting-edge surgical approaches in cataract and refractive patients. Renowned experts with many years of clinical experience describe options such as incisional techniques, toric intraocular lenses, femtosecond and excimer laser technology. In addition, guidance is offered on preoperative evaluation of astigmatism, candidate identification and classification, and surgical management following penetrating keratoplasty. Supplementary videos of informative sample cases are included to further aid everyday practice.

Book Description
The surgical correction of astigmatism is the last frontier to optimizing visual outcomes for patients. Practical Astigmatism: Planning and Analysis is a comprehensive guide to correcting astigmatism from pre-operative planning to post-operative analysis. This provides readers with unique insight to what actually happened surgically: did the astigmatism over or under correct? Was it on-axis or off-axis? With this book, ophthalmologists will be able to analyze previous procedures with the appropriate nomograms and more often achieve targeted outcomes. Dr. Noel Alpins has developed the Alpins Method of astigmatism to provide accurate planning and analysis of astigmatism procedures. His method focuses on analyzing refractive and corneal astigmatism parameters and using the results in future surgery to improve visual outcomes. The importance of the ocular residual astigmatism (ORA) is detailed when planning astigmatism surgery. Practical Astigmatism features vector planning for refractive laser surgery as well as planning and analysis applied to cataract and limbal relaxing incisions, , in addition to demonstrating graphical analysis of astigmatism using high quality vector and fan diagrams, as used in scientific journals. In addition, hemidivisional analysis of the irregular cornea, corneal coupling in incisional and excimer laser surgery for mixed astigmatism and toric IOL planning with total corneal power using corneal topographic astigmatism (CorT total) are addressed as well. Some Questions Answered Inside: What is the difference between regular and irregular astigmatism? How do I diagnose each, and how does this affect my surgical technique? Can I incorporate corneal astigmatism when performing excimer laser surgery? Why are my LRIs undercorrecting the astigmatism? Is it safe to perform excimer laser on keratoconous patients? Which corneal astigmatism measure do I choose and what do I do following a refractive surprise? Practical Astigmatism: Planning and Analysis will help ophthalmologists, optometrists, and technicians alike address each patient’s unique circumstances and act as your in-depth guide to correcting astigmatism. Testimonials... “For more than three decades I have been listening to, arguing with, and admiring the work of Dr. Noel Alpins in the field of astigmatism. Despite his remote location on the small island of Australia, his knowledge of astigmatism is at the peak of Mt. Everest. There are few others who have devoted their careers to understanding and managing astigmatism for which the world of ophthalmology is truly grateful.” - Robert H. Osher, MD “Noel is an original thinker who took on and conquered the complexities of astigmatism analysis, publishing the seminal papers on the way. His work has formed the cornerstone from which our current understanding and management of astigmatism has been built. He is someone from whom we have all learnt a great deal and this book is a testament to this.” - Dan Z Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO

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.
