A cataract is a clouding that develops in the crystalline lens of the eye or in its envelope, varying in degree from slight to complete opacity and obstructing the passage of light. This book reviews research in the field of cataracts inclusive of the application of virtual reality in cataract surgery simulation for ophthalmology training and an analysis of the surface properties of four different intraolcuar lens materials currently used in cataract surgery. Also discussed, herein, is the future of cataract surgeries; disability glare effects and cataracts as a problem of road safety in driving; the pharmacological treatment of ocular inflammatory diseases; among others.

The Ocular Biomechanics Group was established in 2002 with one clear target; to develop a virtual reality model of the human eye that can be used effectively and reliably to predict ocular response to surgery, injury and disease. This ambitious, and seemingly illusive, target helped plan our activities over the last 6 years and will still be focusing our efforts as we strive to create the necessary knowledge using experimental methods, build the predictive tools using programming and analysis means, and validate the findings in both the laboratory and the clinic. This book presents an overview of our biomechanical studies from laboratory material characterisation to finite element numerical simulation. The chapter describes what has been achieved and points at the remaining gaps in our knowledge. It explains that while much remains unknown in ocular behaviour, we are now in a good position to use available knowledge to progress predictive modelling and use it in actual applications such as improving the accuracy of tonometry techniques, planning of refractive surgeries and design of contact lenses. The discussion focuses on the cornea, although scleral biomechanics receive some mention. The chapter also refers to microstructural, biomechanical and topographic studies conducted by other research groups. Coverage of these studies has been necessary to provide a more complete image of current understanding of corneal biomechanics.

The consequences of aging populations combined with the strain to the human eye caused by computers and widespread poor nutritional practices has resulted in an upsurge of research dealing with vision. This new book presents leading-edge research in this field focusing on glaucoma, corneal transplantation and bacterial eye infections.

Retinal tissue may degenerate for a number of reasons. Among them are: artery or vein occlusion, diabetic retinopathy, R.L.F./R.O.P. or disease (usually hereditary). Retinitis pigmentosa, retinoschisis, lattic degeneration, and macular degeneration are characterised by progressive types of retinal degeneration. This book presents the latest research in the field.

The consequences of ageing populations combined with the strain to the human eye caused by computers and widespread poor nutritional practices has resulted in an upsurge of research dealing with vision. This book presents the latest research from around the world in this dynamic field.

Strabismus surgical techniques are now included. There are two new chapters on vision training and case management which will interest optometrists and orthoptists involved in sports vision and in developmental vision therapy. Pre-registration optometrists will find the chapters on routine orthoptic assessment and the PQE examination of particular interest.

Visual dysfunctions can limit children's concentration, self esteem and school success as they struggle to understand fundamentals such as colors, letters and how to judge distance. With the right help, these obstacles can be overcome, allowing children to reach their full potential and see the world clearly. This accessible book explores how visual problems develop and how they can be reversed through effective and efficient visual therapy. It breaks down myths surrounding visual dysfunction and explains in straightforward terms the various conditions that could be impacting a child's perception, even if they have perfect sight. The visual therapy used in behavioral optometry retrains the brain to perform visual skills more effectively. In these pages there is clear guidance on the array of therapies, techniques and aids available, all of which can make a profound difference to a child's life. This introductory guide to behavioral optometry will be a welcome resource for parents and professionals in search of options to help a child who is experiencing visual problems.
