Book Description
The cornea serves as the gateway into the eye for external images. Maintenance of corneal shapes and transparency is critical for refraction. Small changes in the smoothness of the corneal surface or in the total thickness of the cornea can lead to visual distortion. Recently, however, refractive surgery for the transparent cornea has been introduced. In this procedure, the curvature of the cornea is modified either by cutting the stroma or by laser ablation of normal corneal tissue. Given the clinical efficacy of refractive surgery, it is important to understand the anatomical and physiological structure of the cornea such as corneal collagen cross-linking. Multiple commercial femtosecond lasers have been cleared for use by the US Food and Drug Administration for ophthalmic surgery, including use in creating corneal flaps in LASIK surgery. The newest application of femtosecond lasers in ophthalmology is in cataract surgery. In LASIK surgery, all surgery procedures are done in cornea. In cataract surgery, the cornea is also cut with a femtosecond laser. Over the last decade, the field of femtosecond eye surgery has expanded rapidly, supporting the advantages of combined high-ablation precision and minimized collateral tissue effects. One of the most promising applications for femtosecond laser eye surgery has been corneal surgery, namely laser in situ keratomileusis (LASIK) surgery, where the high-pressure laser plasma non-thermally dissociates the dense corneal tissue, thereby enabling lamellar cornea procedures with minimized side effects with the subsequent excimer laser shaping the corneal surface. Millions of people worldwide have been patients for LASIK surgery and have benefited from new forms of technology. LASIK surgery includes three parts: wavefront detection, femtosecond laser flap creation, and excimer laser cornea correction. Some parts of this book focus on femtosecond laser-assisted LASIK surgery, including basic research for femtosecond laser eye surgery and tissue imaging. The newest application of femtosecond lasers in ophthalmology is cataract surgery. Currently, there are a few lasers at or near the point of commercial release, including LenSx (Alcon Laboratories Inc., Fort Worth, Texas), Catalys (Abbott Medical Optics, Santa Ana, California), LensAR (LensAR Inc., Orlando, Florida), Victus (Technolas Perfect Vision and Bausch & Lomb, Rochester, New York), and Femto LDV (Ziemer Ophthalmic Systems AG, Port, Switzerland). All laser systems share a common platformwhich includes an anterior-segment imaging system, patient interface, and femtosecond laser to imageto calculate and deliver the laser pulses. Some parts of this book explain the principle of OCT-guided femtosecond laser cataract surgery. The combination of femtosecond laser surgery and OCT imaging simultaneously guides the development of next generation femtosecond surgical lasers in cataract surgery and explores femtosecond laser surgical strategies.

Book Description
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.

Book Description
This book provides comprehensive coverage of corneal collagen cross-linking (CXL), a major management modality for keratoconus and ectatic corneal disorders. All aspects are covered, including refractive and non-refractive surgery indications, models of application, safety, efficacy, performance, outcome measures, evidence of CXL, complications, contraindications, use in children, and controversies. The discussion reflects the considerable progress that has been made in understanding of the modality since its development in the late 1990s. Detailed attention is paid to new concepts, changing surgical techniques and indications, the latest evidence-based science and research, and the future of CXL. Guidance is also provided on the use of CXL in combination with other modalities, such as LASIK, PRK, intracorneal ring implantation and others. The text is accompanied by numerous high-quality color illustrations. Corneal Collagen Cross Linking will provide the reader with a sound grasp of the technique and its use and will hopefully also serve as a stimulus to further research and advances.

Book Description
Corneal Cross-Linking, Second Edition represents an innovative approach to treating primary acquired and secondary induced ectatic disorders. In addition, corneal cross-linking (CXL) has promising applications as an alternative in the treatment of corneal infectious and non-infectious melting, as well as conditions such as Fuchs’ endothelial dystrophy. The new and expanded Second Edition of Corneal Cross-Linking by Drs. Farhad Hafezi and J. Bradley Randleman will provide a concise yet comprehensive summary of the CXL process, including the basic science foundations, treatment protocols and outcomes, recognition and management of potential complications, and modification of standard protocol for special circumstances. Given all the changes in this rapidly progressing field, many brief topics from the first edition have now grown into full chapters or sections. These include expanded sections on alternative treatment protocols, corneal imaging and biomechanics, combing cross-linking with other refractive treatments, and a section devoted specifically to the most highly debated controversies in the field today. With each chapter being fully updated plus including over twenty new chapters that covers the latest advances and future directions, Corneal Cross-Linking, Second Edition represents the cutting-edge of CXL research and clinical practice. “Since the publication of the first edition of this book in 2013, our knowledge of corneal cross-linking has again significantly increased, both scientifically and clinically. Today, concise recommendations (guidelines for cross-linking) help the clinician to select the patients, make decisions, and provide optimal treatment” -Eberhard Spoerl, PhD and Theo Seiler, MD, PhD
