Modern laser vision correction has continually changed since its inception. The evolution of this procedure has been aided by broad technological advancements, increased surgical knowledge, and increased understanding of the cornea and its response to lasers. PRK: The Past, Present, and Future of Surface Ablation will provide a complete vision of the PRK laser correction techniques that have emerged and the technological advancements that have made them possible. The collaboration of Drs. Buratto, Slade, Serrao, and Lombardo, along with a team of international surgeons have produced a complete book specifically designed to assist clinician’s to improve the quality of their patient’s vision With over 85 color illustrations demonstrating the various procedures and concepts, the book will help ophthalmologists develop a more thorough understanding of PRK. PRK: The Past, Present, and Future of Surface Ablation is excellent for surgeons interested in learning the concepts, developing skills, and preparing for the actual laser procedure. This definitive resource couples both the authors' and 9 contributors' diverse experience and knowledge to produce a complete vision of PRK laser vision correction. PRK: The Past, Present, and Future of Surface Ablation will be the definitive resource necessary for all surgeons aspiring to improve their surgical results using the latest techniques available.

Based on feedback, the authors have streamlined their bestselling reference to zero in on just the clinical answers ophthalmologists need in day-to-day practice. This new edition presents unparalleled guidance on nearly every ophthalmic condition and procedure.

Most of the research efforts dealing with airline scheduling have been done on off-line plan optimization. However, nowadays, with the increasingly complex and huge traffic at airports, the real challenge is how to react to unexpected events that may cause plan-disruptions, leading to flight delays. Moreover these disruptive events usually affect at least three different dimensions of the situation: the aircraft assigned to the flight, the crew assignment and often forgotten, the passengers’ journey and satisfaction. This book includes answers to this challenge and proposes the use of the Multi-agent System paradigm to rapidly compose a multi-faceted solution to the disruptive event taking into consideration possible preferences of those three key aspects of the problem. Negotiation protocols taking place between agents that are experts in solving the different problem dimensions, combination of different utility functions and not less important, the inclusion of the human in the automatic decision-making loop make MASDIMA, the system described in this book, well suited for real-life plan-disruption management applications.

These Proceedings of the Fourth International Congress on the Cornea continue a tradition of summarizing the state-of-the art basic and clinical research in cornea and ex ternal diseases since the first Congress was held in 1964. Reflecting the emerging impor tance of refractive surgery, two of the twelve sessions of the Congress were devoted to refractive surgery; this is reflected in an emphasis in these Proceedings. In addition, an en tire session was devoted to the molecular and cellular biology of the cornea with impor tant new information on the role of growth factors and cytokine modulation of corneal wound healing. Within these Proceedings an international group of expert researchers and practitioners provide the latest insights into the tear film and ocular surface, corneal trans plantation and eyebanking, the corneal stroma and endothelium, contact lenses, microbial and nonmicrobial keratitis, keratoconus, and world corneal health. Notable subjects covered include the latest understanding of the barrier function of the ocular surface epithelium, corneal hydration control, the molecular mechanisms con trolling gene expression in corneal wound healing, stromal~pithelial interactions in the cornea, the immunology of blepharitis, the effect of contact lenses on the conjunctiva, morphologic and functional evaluation of the human corneal endothelium, long-term fol low-up of penetrating keratoplasty in keratoconus, the Tampa trephine penetrating kerato plasty, and the refractive results of the Nidek EC-5000 excimer laser.

The nexus of urban governance and human migration was a crucial feature in the modernisation of cities in the Ottoman Empire of the nineteenth century. This book connects these two concepts to examine the Ottoman city as a destination of human migration, throwing new light on the question of conviviality and cosmopolitanism from the perspective of the legal, administrative and political frameworks within which these occur. Focusing on groups of migrants with various ethnic, regional and professional backgrounds, the book juxtaposes the trajectories of these people with attempts by local administrations and the government to control their movements and settlements. By combining a perspective from below with one that focuses on government action, the authors offer broad insights into the phenomenon of migration and city life as a whole. Chapters explore how increased migration driven by new means of transport, military expulsion and economic factors were countered by the state’s attempts to control population movements, as well as the strong internal reforms in the Ottoman world. Providing a rare comparative perspective on an area often fragmented by area studies boundaries, this book will be of great interest to students of History, Middle Eastern Studies, Balkan Studies, Urban Studies and Migration Studies.

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.
