BOOK REVIEW

Clinical Manual of Contact Lenses, 4th ed., Edward Bennett and Vinita Henry The practice of optometry is an art and a science, and both aspects are well represented in Ed Bennett and Vinita Henry’s Clinical Manual of Contact Lenses.

Philadelphia, PA: Wolters Kluwer/Lippincott Williams & Wilkins; 2014. $99.00

In its fourth edition, this work continues to earn its reputation as a leading comprehensive clinical reference. The authors share their own expertise and incorporate the expertise of a wealth of contributors in a consistent accessible format. It’s a natural choice for students and educators, and anyone who fits contact lenses could benefit from what it has to offer. The range of topics covered in this text is broad, from basic knowledge for the student to advanced techniques for the experienced practitioner, including preliminary examination, gas-permeable and soft lens fitting, astigmatism, presbyopia, a host of specialty lenses, problem solving, and more. This edition has many updates, such as a section on lid wiper epitheliopathy and a chapter on scleral lenses. The content is backed by plenty of science, and the authors do an excellent job of conveying key findings without overwhelming the reader with study details. (That’s what references are for, and they are extensiveVthe overnight wear chapter alone lists 335.) The artistic side is

evident as well. The authors describe their own approaches but take care to include a variety of alternative strategies. Each chapter is well organized and concludes with illustrative examples of the application of the principles to patient cases. The figures are helpful, and the numerous tables are replete with information for easy reference. The index is detailed but even greater search capability is available in the online version of the book, which comes with this edition. There is little to criticize. Certainly, some redundancies may be found between chapters (some facts are relevant to more than one topic), but that is forgivable, considering that it is more likely to be used as a reference than read cover to cover. All in all, there are few flaws in this gem of a book and it is heartily recommended for anyoneVnovice or expertVwho would like to learn more about contact lenses.
