This edition incorporates most recent information in the field of contact lenses reported in scientific literature. The physiology of contact lens is now better understood and sufficient information on subacute inflammation during sleep is available. There is further clarity on the use of PMMA and HEMA lenses with the stress on their cautious use. The text highlights the superiority of gas permeable lenses and also describes the use of toric lenses and the methods for their stabilization. Clinical application of corneal topography while diagnosing corneal pathologies and fabricating contact lenses has been duly underlined. The new information on contact lens fitting after radial keratotomy has opened up a new chapter in this field. The newer refractive procedure, disinfections find an important place in this text which also stresses on the newer methodologies in lens design, and proper care and fitting for reducing the infective morbidity. The text introduces many new topics which should provide wide information to the contact lens practitioners and help them in tackling many day-to-day problems encountered by them. The Textbook is amply illustrated through 108 colour pictures which have been presented in 32 colour plates interspersed in the text for easy location. Every student of ophthalmology and practitioner interested in contact lenses should find this text a useful source and companion in providing a complete range of information on the subject.
