Contact Lens Fitting Guide: This book is a concise guide to contact lens fitting for optometrists and trainees. Beginning with an introduction to contact lenses and the pre-contact lens fitting eye examination, making sure a patient is suitable for wearing contact lenses, the following chapters describe the fitting of different types of corrective lens – soft, toric and rigid gas permeable. Separate chapters examine the use of therapeutic contact lenses, used to protect the eye whilst it heals after injury or infection, rather than to correct vision; and lenses for presbyopia, age-related long-sightedness.

Clinical Manual of Contact Lenses: Designed to be used as a quick reference, this fourth edition of the Clinical Manual of Contact Lenses allows readers to easily find the topic and information they need without having to search through an entire chapter to find it. Rigid gas permeable lens design and fitting, soft lens problem-solving, astigmatic management, and bifocal correction are just a few of the subjects covered in this manual. Each chapter includes sample cases to reinforce and demonstrate the practical nature of the topic, with nomograms and proficiency checklists summarizing and emphasizing the important points. With this guide, students and practitioners will have a dependable resource to help fit, evaluate, and troubleshoot any contact lenses, especially specialty designs for years to come.

Contact Lenses in Ophthalmic Practice: Even with the advances in intraocular lens technology and the growing diversity of refractive surgery techniques, the role of contact lenses in ophthalmic practice has only increased. This is due in part to the great strides in materials, technology, expanding applications (both refractive and therapeutic) for contact lenses, and the clear recognition that contact lenses will always be an important tool for the ophthalmologist. With the fitting of contact lenses as a medical art, requiring a thorough understanding of anatomy, physiology and optics of the eye, this practice is formulaic only in part. The rest of contact lens practice requires sound medical judgment and decision- making that comes only with “hands-on” experience. The authors address this need by starting with a didactic approach that incorporates frequently-asked questions and straightforward answers so that the ophthalmology resident, intermediate contact lens practitioner, and optometrist will find this to be an indispensable resource.
