      This book is written for students of English who are interested in the history of the language and would like to read an accessible but also comprehensive and reasonably detailed introduction. Apart from basic information about language change and the Indo-European background of English, it gives an outline of the major periods of the language (Old English, Middle English, Early Modern English and Late Modern English), with a brief examination of the perspectives of present-day English. Each period chapter provides information about the socio-historical background, the core areas of linguistic structure, discourse, speech acts and genres, and concludes with study questions and exercises.

      New cataract removal techniques, anesthesia and viscoelastic substances, and the implantation of modern intraocular lenses are essential topics in the fast developing field of ophthalmic surgery. This publication provides a comprehensive update discussing these items thoroughly. Special emphasis is given to the management of mature cataract and phacoemulsification in the vitreous cavity. Intraocular lens calculation is highlighted by optical coherence biometry, in particular, the measurements to increase the predictability of intraocular lens implantation. Implantation techniques, incision architecture and wound construction as well as Scheimpflug-photography of foldable intraocular lenses and the prevention of PCO (posterior capsular opacification) are covered. The last two articles emphasize the implantation of special intraocular lenses including piggyback intraocular lens and multifocal intraocular lens implantation. Anterior eye segment surgeons looking for an update on modern cataract surgery will find a wealth of timely information on new techniques and results in small incision cataract surgery in this publication.
