Download or read book Refractive Surgery written by J. Bradley Randleman and published by CRC Press. This book was released on 2024-06-01 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Refractive Surgery: An Interactive Case-Based Approach presents all of the necessary refractive surgery material to make an informed decision regarding diagnosis and management plans. Rather than utilizing the standard organization of most books, where major points are first introduced and then explained through a series of writings and references, this book relies on the clinical decision-making process involved with treating refractive surgery patients. Refractive Surgery: An Interactive Case-Based Approach by Dr. J. Bradley Randleman builds upon foundational initial chapters through the case presentations and focused case discussions, encompassing the major topics in refractive surgery today. For each case, the critical question is simply, “what data in this chart is the most critical to consider when evaluating this patient for surgery?” Refractive Surgery: An Interactive Case-Based Approach is unique in its format. Specifically, the book facilitates active learning by forcing the reader to think through a series of questions surrounding each patient scenario. This active learning not only facilitates better recall of the information presented but also mimics the actual physician-to-patient clinical experience, making this book more relevant than other routine refractive surgery books. Bonus! This dynamic learning tool is also supplemented by interactive online video material to further the learning experience. Enhance the clinical decision-making process by watching the videos and then answering a series of questions that lead to the conclusion of each scenario. By challenging the reader to perform the thinking and decision making up-front, and then providing some guidance on the most salient concepts for each case scenario presented along with resources to gain a deeper understanding of the most complex concepts, Refractive Surgery: An Interactive Case-Based Approach engages more in the learning process and thereby allowing to absorb and retain significantly more information to apply to patient care and the education of others. Ophthalmologists, residents, fellows, resident and fellowship educators, who want to update their refractive surgery knowledge base will appreciate the unique format and style of Refractive Surgery: An Interactive Case-Based Approach.

Download or read book Corneal Biomechanics written by C.J. Roberts and published by Kugler Publications. This book was released on 2017-05-15 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: While lecturing in recent months at a number of prominent institutions, I asked some of the residents and fellows whether and how they might benefit from a book on corneal biomechanics. The typical response was the look of a deer caught in the headlights as they tried to intuit the “appropriate” answer, but had little understanding or insight as to why this would be an important and useful knowledge base for them now, or in the future. I then posed the question differently. “Would a book that explained corneal biomechanical principles and testing devices and their application in detecting eyes at risk for developing keratoconus and post-LASIK ectasia, understanding the biomechanical impact of specific types of keratorefractive surgery and riboflavin UV-A corneal collagen cross-linking, and the impact of corneal biomechanics on the fidelity of intraocular pressure measurement and risk for glaucoma progression be of interest?” Framed in this context, the answer I got was a resounding, “Yes!” Therein lies a fundamental disconnect that highlights both the opportunity and need to educate all ophthalmologists about this nascent field. This comprehensive book is strengthened by the breadth of contributions from leading experts around the world and provides an important resource for ophthalmologists at all levels of training and experience. It gives a panoramic snapshot of our understanding of corneal biomechanics today, bridging the gap between theoretical principles, testing devices that are commercially available and in development as well as current and potential future clinical applications. While there has been a long-held appreciation that all types of keratorefractive surgery have an impact and interdependence on corneal biomechanics and wound healing, the initial finite element analyses that were applied to understand radial keratotomy were limited by incorrect assumptions that the cornea was a linear, elastic, homogenous, isotropic material.1 With the advent of excimer laser vision correction, critical observations indicated that Munnerlyn’s theoretic ablation profiles did not account for either lower or higher order (e.g. spherical aberration) refractive outcomes,2 suggesting that there were important components missing from the equation—e.g., corneal biomechanics and wound healing. In a seminal editorial, Roberts3 pointed out that the cornea is not a piece of plastic, but rather a material with viscoelastic qualities. Since that time, much has been learned about spatial and depth- related patterns of collagen orientation and interweaving, as well as the biomechanical response to different keratorefractive surgeries that sever tension-bearing lamellae, as the cornea responds to and redistributes stress induced by IOP, hydration, eye rubbing, blinking and extraocular muscle forces.3-6 The first reports of post-LASIK ectasia7 highlighted the need to identify a biomechanical signature of early keratoconus as well as corneas at high risk of developing ectasia irrespective of their current topography or tomography. The introduction of two instruments into clinical use—the Ocular Response Analyzer (ORA) and the Corneal Visualization Scheimpflug Technology (Corvis ST)—that allow measurement of various biomechanical metrics further catapulted the field. The availability of these instruments in routine clinical settings allowed the systematic study of the effect of age, collagen disorders, collagen cross-linking, corneal rings, flaps of various depths, contour, sidecut angulation, pockets, and flockets, just to name of few. Future application of biomechanics to the sclera may improve our understanding of the development and prevention of myopia, as well as scleral surgeries and treatments under development for presbyopia. It was appreciated by Goldmann and Schmidt that corneal thickness and curvature would influence the measurement of applanation tonometry. The recent ability to measure some corneal biomechanical metrics have led to IOP measurement that may be more immune both to their influence and the impact of central corneal thickness (CCT). Certain chapters in this book explain how a thin cornea could be stiffer than a thick one and that stiffness is also impacted by IOP, thereby precluding simplistic attempts to adjust IOP measurements using nomograms based upon CCT alone. Also highlighted is how corneal hysteresis, the ability of the cornea to absorb and dissipate energy during the bidirectional applanation response to a linear Gaussian air puff, appears to be an independent risk factor for glaucoma progression and rate of progression.9,10 This comprehensive book starts out with a section devoted to outlining basic biomechanical principles and theories, teaching us the language of what Dupps11 has referred to as “mechanospeak”, thus providing a context and common vocabulary to better comprehend the following chapters. By first defining basic concepts such as stress-strain relationships and creep, this theoretical basis is later applied to explain the pathogenesis of corneal diseases, e.g., explaining how a focal abnormality in corneal biomechanical properties precipitates a cycle of decompensation and localized thinning and steepening, clinically expressed as ectasia progression. These early chapters further detail biomechanical differences between in-vivo and ex-vivo testing, between human and animal corneas and sclera, and between methods of testing. The second section provides a thorough description of two FDA-approved devices to measure corneal biomechanics in the clinic (i.e., the ORA and the Corvis ST), as well as an overview of potential future technologies, including OCT with air puff stimulus, ocular pulse elastography, and Brilloiun microscopy. The third and final section of the book is a thorough treatise on how to interpret the metrics derived from the waveform provided by available clinical devices; their adjunct use in ectasia risk screening; the comparative biomechanical impact of various keratorefractive surgeries and corneal procedures such as PRK, LASIK, SMILE, and corneal collagen cross-linking; the impact of corneal biomechanics on IOP measurement; and potential biomechanical markers of enhanced susceptibility to glaucoma progression. This compendium of our current knowledge of corneal biomechanics, its measurement and application, provides a strong foundation to more fully understand advances in keratorefractive and corneal surgery, diseases, and treatments, all of which are interdependent on and influence inherent corneal biomechanical properties and behavior. Both the robust aspects and limitations of our current understanding are presented, including the challenge of creating accurate and predictive finite element models that incorporate the impact of IOP, corneal thickness, geometry, and scleral properties on corneal biomechanics. This book provides a key allowing clinical ophthalmologists and researchers to grasp the basics and nuances of this exciting field and to shape it as it evolves in the future.

Available in PDF, EPUB and Kindle. Book excerpt: The incidence and prevalence of high myopia has increased significantly over the past decade and is expected to more than double over the next 20 years. These patients are more impacted by their vision than patients with lower refractive errors, and also have more limited safe and effective treatment options available to them. Fortunately, recent developments in the field have improved refractive surgery screening to improve safety, and new surgical options are now available specifically to address these more complex refractive errors. The book will address the unique challenges presented by patients with high myopia and cover the pros and cons of current treatment options. The book will also feature case studies, with detailed images and tables. In addition, the book will discuss promising future options currently in development. Refractive Surgery for High Myopia is a must-have resource for ophthalmologists, refractive surgeons, residents, and fellows.
