In Sean McMullen's glittering, dynamic, and exotic world two thousand years in the future, librarians fight duels to settle disputes, there is no electricity, fueled engines are banned by every major religion in Australica, humanity has split into two species, and intelligent cetezoids rule the oceans. In space, the enigmatic Mirrorsun has begun to spin. Immense solar sails are pushing vast amounts of energy into its ancient orbital band, energy that could tear it apart--or be directed down at Earth. Already the hypnotic Call has ceased, and all electrical machines have been reduced to molten metal. A religious prophet has risen and is attempting to bring together the entire continent of Australica under her rule. Meanwhile, her diesel-powered sailwing shot down by religious fanatics, the American princess Samondel is forced to set aside her trade-seeking mission and disguise herself as a student. Her only friends are a disgraced monk who is a member of the secret police and a beautiful young librarian who is a dangerous and unstable psychopath. From these unlikely friendships she must form an alliance between two continents and two species, and prevent ultimate war. Fundamentally, unexpectedly, things are changing everywhere. As catastrophe looms and civilization begins to crumble, the Dragon Librarians of Australica have just one means left to hold their world together: to kidnap every numerate person on the continent and rebuild their out-of-date human-powered computer--the Calculor. At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

An Australia destroyed by a nuclear holocaust is ruled by a computer made of human components imprisoned inside. When a component becomes defective it is shot.

The selection of appropriate formulas and surgical techniques is vitally important to best fulfill each patient's visual needs and expectations. With over 30 years of experience, H. John Shammas, MD clearly explains the importance of intraocular lens (IOL) power calculations during preoperative cataract evaluation and their role in positively improving surgical outcomes. Intraocular Lens Power Calculations addresses both currently used and the latest, more advanced formulas. To fully understand the application of these formulas in various situations, thorough explanations are provided. Numerous highlighted clinical applications, case reports, figures, and tables are also utilized to illustrate and reinforce key points. This well-organized text contains the most up-to-date information on axial length measurement, biometry units, constants, and ways to avoid errors. IOL power calculations and selection are included for an array of conditions ranging from the normal phakic eye to the more challenging high myopic and high hyperopic eyes, piggyback implantation, intumescent cataract, and the aphakic eye. Intraocular Lens Power Calculations updates surgeons, technicians, and students on all the techniques and formulas available to achieve the most accurate and precise calculations, thus paving the way for surgical results that fulfill patients' visual needs.

Zusammenfassung: Cataract surgery, with 25-30 million surgeries per year, has become one of most popular surgeries in the world. The calculation of its power is of utmost importance. As new premium intraocular lenses (IOLs) and modern surgical techniques have been developed, the demand has grown exponentially - not only for eliminating cataracts, but also for getting rid of the need for glasses. This book offers a comprehensive overview of IOL power calculations and its various formulas and methods. Chapters discuss use of the diagnostic biometry devices that provide the measurements and the management of different clinical situations where particular modifications must be applied. Chapters also discuss the newest generation of multifocal and toric IOLs that can only be implanted if no residual refraction is planned for, which implies a perfect mastery of all the IOL calculation process. This book marks the first time in ophthalmological history that all the main leaders in the field have collaborated in a project that will undoubtedly be the reference for the next ten years. Intraocular Lens Calculations is a must-have resource for cataract and refractive surgeons as well as technicians and anyone dealing with this subject
