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 Femtosecond Laser in Refractive and Cataract Surgery written by Hui Sun and published by . This book was released on 2018 with total page 0 pages. 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.
Download or read book Corneal Collagen Cross linking and Its Many Benefits written by Craig Jensen and published by . This book was released on 2014 with total page 44 pages. 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.

This book was released on 2013-03-31 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Keratoconus is degeneration of the structure of the cornea. The cornea is the clear tissue covering the front of the eye. In keratoconus, the shape of the cornea slowly changes from round to conical (PubMed Health). In the early stages, keratoconus can be corrected with the use of lenses, but in the later stages, surgery is the only option. Holcomb C3-R® is a non-surgical technique that involves placing drops of the vitamin Riboflavin into the eye and using a UV light to activate them. The drops strengthen the fibres of the cornea and over time, preserve sight (American Keratoconus Association). This book is a concise guide to the technique of Holcomb C3-R® to treat keratoconus. Authored by the inventor of the procedure, Brian S Boxer Wachler, the text is based on his first hand clinical experience and explains the history and basic science of cross linking, the development and naming of the technique, its uses and complications, and first patient results. Key points Concise guide to technique of Holcomb C3-R® to treat keratoconus Authored by inventor of the technique and based on clinical experience Includes more than 60 full colour images and illustrations

Download or read book Corneal Collagen Cross link Therapy for Keratoconus written by Joren Bonderud and published by . This book was released on 2017 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Keratoconus is a corneal condition that affects 1 in 2000 people. It causes symptoms including blurry, distorted, and irregular vision that cannot be fully corrected by traditional glasses. Patients with this condition can suffer a decrease in the quality of their life, depending on the severity and progression of the disease. In severe cases, a corneal transplant is needed which can be dangerous, expensive, and ultimately unsuccessful. Corneal Collagen Cross-linking is a procedure that involves treating the eye with topical Riboflavin (Vitamin B2) and Ultraviolet light in order to strengthen the thinning corneal tissue. This procedure has given eye professionals hope for reducing the need for corneal transplants. Also, there is evidence that this procedure can reduce the incidence of severe complications. The information in this literature review is provided by the tireless effort of researchers from 1998 until the present.

Book excerpt: First developed in Dresden, Germany, corneal collagen crosslinking (CXL) is a treament that has been around for approximately 15 years. CXL has been used to help slow the progression of actasia and has been used to stabilize corneal disorders such as, keratocconus, pellucid marginal degeneration, and ectasia after LASIK surgery. Due to the success rate and minimal side effects of CXL, researchers have been rying to increae the scope of the procedure to perhaps be used in pediatric keratoconus, keratitis, Fuchs corneal dystrophy, and potentially other corneal dystrophies. Several experimental and retrospective studies have been performed to assess the effects and results of CXL in these corneal dystrophies. Many of theses studies have found some benefits with the use of CXL early in patients with debilitating corneal diseases but how safe is the procedure and its is it effective long term?
