Book Synopsis Corneal Collagen Cross Linking by : Mazen M. Sinjab

Download or read book Corneal Collagen Cross Linking written by Mazen M. Sinjab. This book was released on 2016-11-09. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Corneal Collagen Cross-linking and Its Many Benefits written by Craig Jensen. This book was released on 2014. Available in PDF, EPUB and Kindle. Book excerpt: Corneal collagen cross-linking has been around for thousands of year. Only recently has it been studied more in depth as a way to control keratoconus. Up until recently, this has been the only treatment considered in collagen cross-linking. However, more recent studies have found many alternative treatment options for corneal collagen cross-linking. Currently, studies into benefits of collagen cross-linking range from treating thin corneas, and those with other form of ectasia, to treating edematous or bullous corneas. Studies for treatment options have also branched into ways of treating infectious keratitis, to even utilizing collagen cross-linking as a means of controlling low amounts of ametropia, as a stand-alone treatment, or used in conjunction with other refractive corneal surgeries. Currently, Collagen cross-linking is a standard of care in many international countries, however, in the United States, it has yet to pass through national acceptance and approval. The benefits of collagen cross-linking as a treatment option for a broad array of corneal conditions are becoming increasingly obvious.

Book Synopsis Corneal Collagen Cross-linking and Femtosecond Laser in Refractive and Cataract Surgery by : Hui Sun

Download or read book Corneal Collagen Cross-linking and Femtosecond Laser in Refractive and Cataract Surgery written by Hui Sun. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Corneal Cross-Linking by : Farhad Hafezi

Download or read book Corneal Cross-Linking written by Farhad Hafezi. This book was released on 2024-06-01. Available in PDF, EPUB and Kindle. Book excerpt: 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
