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.

This book addresses customized laser vision correction, an integral management option for the treatment of irregular corneas. This type of treatment reshapes the corneal surface in order to improve both the quality and the quantity of vision by reducing high order aberrations. Beginning with an introduction to the basics of this science, each type of customized laser vision correction is discussed in a clear and didactic format for rapid attainment of information. Throughout this practical clinical guide, examples are supported with the most recent scientific material and a step-by-step systematic methodology is included to fit all levels of ophthalmologists.

Abnormal or deficient capsular anatomy creates numerous surgical challenges and predisposes eyes to IOL complications. Literally dozens of different approaches have been devised to implant IOLs in the face of compromised capsular support. However, a comprehensive compendium of the most important surgical strategies has not existed, until now. Advanced IOL Fixation Techniques:Strategies for Compromised or Missing Capsular Support provides this much-needed resource with more than 70 different chapters that cover the wide array of surgical approaches. Among the contributors are many of the original innovators of the most important technologies and methodologies. In addition to teaching a specific surgical technique, these authors cover its history, rationale, and clinical results. Editor Dr. David F. Chang is well known and acclaimed for 2 best-selling cataract textbooks—Mastering Refractive IOLs and Phaco Chop and Advanced Phaco Techniques. Along with associate editors Drs. Bryan S. Lee and Amar Agarwal, Dr. Chang has now tackled this new major subject area—how to best fixate IOLs when capsular support is compromised or absent. Part One covers capsular fixation with either zonulopathy or following posterior capsule rupture. Topics include using conventional and modified capsular tension rings, capsular tension segments or capsular anchors, standard and reverse optic capture with anterior capsulorrhexis, sulcus fixation, posterior capsulorrhexis, and capsular membrane suture fixation. Part Two covers noncapsular fixation. Topics include anterior chamber IOLs, iris claw IOLs, iris and transscleral suture fixation of posterior chamber IOLs, and intrascleral haptic fixation using the Yamane double-needle or glued IOL methods. Part Three covers miscellaneous topics such as anterior vitrectomy, IOL power calculation for noncapsular IOLs, and sliding slip knots and suture pupilloplasty. To facilitate skills transfer, most chapters present detailed, step-by-step descriptions of the different techniques. The maneuvers are illustrated by over 1,100 diagrams and high-resolution surgical images. Finally, nearly every chapter is accompanied by narrated instructional videos. Combining over 150 videos, schematic diagrams, surgical images, and detailed written descriptions, Advanced IOL Fixation Techniques provides the most effective way to learn advanced surgical techniques. With its comprehensive and practical approach to covering the gamut of strategies and devices, Advanced IOL Fixation Techniques:Strategies for Compromised or Missing Capsular Support will be an indispensable resource for cataract surgeons at all levels of experience.

The book covers various aspects of the management of keratoconus, which is a leading cause of visual impairment in young adults. It focuses on the epidemiology and risk factors of keratoconus with a special focus on Southeast Asia. Keratoconus affects the quality of vision, thereby affecting the quality of life. While most patients present with defective vision, many are diagnosed accidentally during screening for refractive surgery. The book covers the varied epidemiology of keratoconus across different parts of the world. It discusses many systemic and ocular diseases associated with keratoconus. The book covers the newer diagnostic techniques and various treatment procedures for keratoconus, helping in diagnosing keratoconus in the early stages and closely watching the progression. It discusses various contact lenses to improve vision quality; widely used collagen crosslinking, and its various modifications for halting the progression. It also explains the surgical approach for keratoconus, such as penetrating keratoplasty, lamellar keratoplasty and other lens-assisted procedures. The book is relevant for general ophthalmologists and cornea specialists.

A comprehensive reference for physicians, surgeons, and trainees, Atlas of Corneal Imaging covers all aspects of corneal imaging from basic map interpretation to advanced diagnostic uses and features over 1200 illustrative images and figures representing a wide variety of devices and techniques. Drs. J. Bradley Randleman, Marcony Santhiago, and William J. Dupps Jr guide readers through the process of analyzing corneal images using a multitude of different techniques, technologies, and individual devices. This creates a complete picture of the cornea’s basic methods and pathological processes and allows readers to directly visualize how their technology would display the pathology in question. Atlas of Corneal Imaging is designed to help practitioners recognize subtle findings and evaluate signs of weakening or pathology, no matter how they present or what device is being used. Multiple iterations of the same clinical condition are shown with numerous complementary images for the same eye to provide a comprehensive presentation of each case. Chapters feature information on: Topographic patterns and mapping Corneal ectasia evaluations Cornea and refractive surgery evaluations Clinical correlations with corneal disorders Cornea and refractive surgery complications Evaluation for cataract surgery Atlas of Corneal Imaging fills a significant void in corneal imaging resources available today by presenting an image-first approach to understanding all the many different technologies for imaging the cornea.

Refractive surgery is eye surgery to improve the refractive state of the eye and reduce or eliminate the need for glasses or contact lenses. The most common type of refractive surgery uses lasers to reshape the curvature of the cornea. This book is a practical guide to the latest advances in refractive surgery procedures. Beginning with an introduction to the evolution of refractive surgery, the next section discusses pre-operative workup, patient evaluation, and decision making. The following sections cover different refractive procedures including corneal ablative, refractive lenticule extraction, lens-based surgeries, enhancements and retreatments, and presbyopia (a condition associated with aging). The final section covers a selection of miscellaneous topics such as bioptics, collagen cross-linking, intracorneal ring segments, incisional surgery, and challenging scenarios. Each section is highly illustrated and provides in depth detail on machines and laser platforms, surgical techniques, outcomes, and potential complications and their management.
