Download or read book Step by Step Corneal Topography written by Sunita Agarwal and published by CRC Press. This book was released on 2005-01-13 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given that most ophthalmic surgeons have at some time in their careers struggled with reading a corneal topography map and attempting to ascertain if it is normal or abnormal, this handy step by step guide to corneal topography is an excellent aide-memoire. The illustrious Agarwal family cover the common use of corneal topography - keratoconus detection – as well as more unique areas such as the extensive use of corneal topography for cataract surgery and phakonit, as well as posterior corneal topography, and aberropia. Going one step further than many other texts in the field, this impressive guide also presents splendid information on the use of topography for aberrometry-guided excimer laster applications. Making the difficult and often confusing mixture of art and science that is corneal topography seem more manageable in day-to-day practice, Step by Step Corneal Topography is undoubtedly requisite reading for all ophthalmologists.

Book Synopsis Atlas and Clinical Reference Guide for Corneal Topography by : Ming Wang
Download or read book Atlas and Clinical Reference Guide for Corneal Topography written by Ming Wang and published by CRC Press. This book was released on 2024-06-01 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corneal topography has become essentially a pattern recognition trade, best learned by viewing multiple images of representative patterns. In spite of this, currently available topography books focus only on the technology behind topography, or a particular application of topography, as opposed to presenting a comprehensive collection of topographic patterns that provide quick, consistent pattern recognition and identification. Drs. Wang and Kugler, along with Drs. Morgan and Boerman, look to fill this void with Atlas and Clinical Reference Guide for Corneal Topography. Atlas and Clinical Reference Guide for Corneal Topography is the first corneal topography book that lends itself to efficient image search and reference for busy clinicians at chair side. Organized into both map-based and disease-based sections, the book allows for quick reference in busy clinical situations. Images come from the commonly used topographers, the Zeiss Atlas and the Oculus Pentacam, but the principles of pattern recognition can be applied to any topographer. Due to the text’s large collection of topographic images and corresponding corneal conditions, Atlas and Clinical Reference Guide for Corneal Topography can be used side by side with the topographer. Designed as both a learning tool for students and a reference for clinicians to use when faced with a challenging topography interpretation, Atlas and Clinical Reference Guide for Corneal Topography will be appreciated by a wide spectrum of eye care professionals. General ophthalmologists, cataract and refractive surgeons, corneal specialists, optometrists, and ophthalmology residents and students will benefit from this invaluable atlas for corneal topography.

Book Synopsis Irregular Astigmatism by : Tracy Schroeder Swartz
Download or read book Irregular Astigmatism written by Tracy Schroeder Swartz and published by SLACK Incorporated. This book was released on 2008 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the advent of keratorefractive surgery and its rising popularity, irregular astigmatism has become an increasingly important issue for ophthalmologists and optometrists. Despite the success of LASIK and PRK, there are more and more patients experiencing visual quality problems due to the non-physiological modification of the corneal structure. Among these complications, irregular astigmatism is perhaps the most difficult to treat. Every physician who performs keratorefractive surgery understands that in reducing a patient.s refractive error, there is a possibility of creating irreversible effects on visual quality. This text is intended to help prevent and reduce the iatrogenic creation of irregular astigmatism, as well as provide effective treatment when postoperative complications do arise. With the maturation of keratorefractive technology in recent years, effective treatment for iatrogenic irregular astigmatism is quickly developing. It provides everything refractive surgeons, ophthalmologists, and optometrists need to know about this important topic.
Download or read book Keratoconus written by Jorge L. Alió and published by Springer. This book was released on 2016-12-28 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a degenerative disorder of the eye, keratoconus can cause substantial distortion of vision, with multiple images, streaking, and sensitivity to light all reported by patients. Keratoconus: Recent Advances in Diagnosis and Treatment updates ophthalmologists about the innovations that have occurred within the last decade, discussing the diagnostic imaging techniques that have been developed for keratoconus diagnosis, understanding of how examination techniques are related to the evolution of keratoconus, and how to indicate the different therapeutic tools that have been created for keratoconus over the last several years. Additionally, fundamentals for new diagnostic elements, based on the mathematical, physical and biomechanical data are analyzed in depth for a better understanding of the essential diagnostic steps for the clinician to guide patients towards the most adequate therapeutic tool in the case. Modern keratoplasty techniques, assisted by femtosecond lasers or other devices, are also covered and these techniques, along with the emerging conservative treatments, have added to more precise control of the evolution of the disease.
