Phacoemulsification, the gold standard for cataract extraction, is highly successful. However, the procedure is not without risks and complications. Poor visual outcome, retinal detachment, infection, diplopia, and cornea and iris problems may pose considerable challenges. Additional potential problems arise from implanting the intraocular lens (IOL). Edited by a renowned master surgeon and educator in the field, and authored by a remarkable cast of cataract experts, this is the definitive text on managing cataract surgery, with practical guidance on recognizing and managing complications, should they arise. Experts demonstrate the right way to perform phacoemulsification and diverse surgical and intraocular lens implantation procedures in order to reduce risk and improve patient outcome. This second edition is greatly expanded in size and scope to accomodate the latest state-of-the-art methodologies and refinements in surgical strategies. Since the first edition was published, new techniques for refractive cataract surgery, vitrectomy, IOL exchange, and management of IOL implantation without capsular bag support have been improved. Additionally, new technologies have been introduced such as optical coherence tomography, FLACS (femtosecond laser surgery), and implantation of toric and multifocal refractive IOLs, as well as methods to improve IOL power calculation and decision making. Highlights A stellar group of national and internationally renowned eye surgeons provide invaluable clinical pearls gleaned from years of refining proceduresSurgical videos further elucidate the most optimal surgical strategiesMore than 600 superb illustrationsManagement of challenges including small pupils, IFIS, zonular weakness, inadequate capsular support, vitrectomy, corneal burns, high astigmatism, dysphotopsias, and endophthalmitisThis invaluable reference will help opthalmologists refine their expertise, resulting in fewer risks and more efficacious outcomes. It is a must-have resource for opthalmology residents and proficient surgeons alike.

The main purpose of this book is to remind new engineers in silicon foundry, the fundamental physical and chemical rules in major Front end treatments: oxidation, epitaxy, ion implantation and impurities diffusion.

Cardiac resynchronization therapy is a new therapy for advanced heart failure patients. This therapy has been shown to improve quality of life, exercise capacity, NYHA classification, and even reverse the detrimental «reverse remodeling» that occurs in advanced heart failure – in patients already receiving optimal pharmacological therapy. The typical patient has NYHA III/IV HF symptoms, a QRS > 120 ms, LVEDD > 55 mm, without any indication required for pacing. The therapy is available in an ICD device, too. CRT has been shown to be effective in patients with both ischemic and non-ischemic cardiomyopathy. The implant procedure is part of a learning curve. Many physicians who already perform electrophysiology procedures, or PPM, or ICD implants are the ideal implanter – but are surprised at the challenges this implant presents. This book will help «flatten» the learning curve for new physician implanting, and will provide a "guide' for those who have already started implanting. The success rate is about 90% – so after 10 years of application, we have found that there are still patients who do not get access to this great therapy because of the complexity of the patient's anatomy, or physician skills. The book is written by three authors with a great deal of experience culminating in over 3000 cases between them. This book is intended for cardiologists who currently implant either or both pacemakers and cardioverter defibrillators with cardiac resynchronization therapy (also called bi-ventricular pacing), or plan to implant in the future. This book will be extremely useful for the new cardiologist in training who is learning to implant devices.

The Novartis Foundation Series is a popular collection of the proceedings from Novartis Foundation Symposia, in which groups of leading scientists from a range of topics across biology, chemistry and medicine assembled to present papers and discuss results. The Novartis Foundation, originally known as the Ciba Foundation, is well known to scientists and clinicians around the world.

Preimplantation Genetic Diagnosis (PGD) is the detection and screening of genetic abnormality in gametes prior to fertilisation and embryos fertilised in vitro prior to implantation. This exciting new text provides an introduction and overview of the principles of PGD. An exciting fusion of prenatal diagnosis (PD) with in vitro fertilisation (IVF), this book is will appeal to both the prenatal diagnosis community, of clinical geneticists and foetal medicine specialists within obstetrics and gynaecology, and the IVF community within reproductive medicine. It is also an essential introduction to PD, clinical genetics and IVF for non-specialists. A concise introduction to the field of PGD Detailed explanations of the techniques and procedures used The law and ethical implications of PGD Future uses of PGD

Examines the establishment of the germ layers and other cell lineages in the early embryo including details of cell movements during the beginning stages of primitive streak formation. Discusses patterns of gene expression during the development of such tissues as the limb bud, skeletal, muscle and the central nervous systems placing special emphasis on commitment to particular cell types. Although it concentrates on the mouse as an example of mammalian development–chick, amphibian and Drosophila embryogenesis are employed whenever these organisms are more applicable to the study of a particular problem.
