Description
Book SynopsisAstigmatism means the eye is shaped like a rugby ball so light is focused at more than one place in the eye. It is associated with short or long sightedness and can cause blurry vision, headaches and eye strain. Astigmatism is usually corrected with glasses or contact lenses.
This book is a complete guide to the surgical management of astigmatism.
Based on scientific evidence and practice, the text covers numerous diagnostic and treatment techniques for both regular and irregular astigmatism, including laser surgery and incisional and intraocular lenses.
Each procedure is explained in detail describing new diagnostic technologies, patient selection, methods and limitations across applications.
Authored by an internationally recognised team of experts, the comprehensive text is further enhanced by more than 350 clinical photographs, diagrams and figures.
