This book presents the basic facts of viscoelastic substances. It introduces new, self-obtained data regarding viscoelastic rheological properties and describes the selective usages of viscoelastics in ophthalmic surgery. A clear and understandable presentation of viscoelastic physicochemical properties is emphasized to provide the practicing ophthalmic surgeon a reference guide for the selection of a suitable viscoelastic. The authors detail the broad range of viscoelastic applications, the latest trends in visco-surgery, and describe the complications arising from different surgical techniques with certain viscoelastics. Information on the production of viscoelastic substances is also included. Tables and figures are used to document research results and facilitate understanding, while a subject index and an extensive bibliography provide easy references. This book systematically presents basic knowledge and offers insight into the lastest applications in surgery as well as the most recent, relevant findings in the field of viscoelastic research.
