Stay up to date with the latest advances and concepts in contact-lens-related ocular pathology, including findings from the Dry Eye Workshop (DEWS), the International Workshop on Meibomian Gland Dysfunction, a new approach to corneal inflammatory events and microbial keratitis, and new instrumentation and techniques for anterior eye examination. Consult the most comprehensive and widely-used grading system available, as well as 350 new references that reflect an evidence-based approach, and dozens of superb new illustrations that help you instantly recognize clinical signs.
A widely popular option for vision correction, contact lenses are also useful for the treatment of many serious optical disorders. Like any therapeutic tool, however, they have both positive and negative effects, and a variety of complications can result from their use. Diagnosing and treating these complications and injuries - which sometimes mimic eye diseases - can be complex.Drawing on more than 25 years of knowledge and experience, CONTACT LENS COMPLICATIONS is the first text to provide a practical, comprehensive overview of the eye injuries caused by wearing contact lenses.This book is filled with hundreds of outstanding, full-color illustrations of problems associated with contact lenses, including eyelid lesions, eye tears, hygiene complications, and lens accidents. You will learn how to confidently manage these problems and effectively distinguish them from common ophthalmic diseases.Additionally, the book covers: treatment guidelines; patient examination and counseling; types of contact lenses available today; common lens fitting and wearing problems; and much more!- More than 450 exquisite color photographs and illustrations to facilitate quick injury/disease diagnosis- Meticulous, step-by-step techniques for eye examination- Easy-to-understand terminology, even to those new to contact lens patient care- Clear and concise disease prevention guidelines- Practical patient management tipsCONTACT LENS COMPLICATIONS gives medical professionals factual, clear, current information on the injuries and complications caused by wearing contact lenses. Essential for anyone involved in vision care, this authoritative and eminently practical work is certain to become a key resource in the field.
From the reviews: "The full title is Common Contact Lens Complications - Their Recognition and Management and it perfectly sums up the appeal of this little book. ... For students it is a 'must have', but it is a great addition to anyone's reading list, whether student, supervisor or just a jobbing practitioner." Optician
Contact lenses are not without risks. They rest directly on the tear film, which lubricates the cornea and conjunctiva. They have the potential to disrupt the tear film and the normal physiology of the ocular surface. Hypoxia associated with contact lens wear is thought to facilitate the development of complications such as vascularization, edema, corneal ulcers, contact lens-superior limbic keratoconjunctivits (CL-SLK), corneal striae, limbal hyperemia, and epithelial microcysts. Contamination is another major concern. Acanthamoeba keratitis is a rare but dangerous corneal infection with the protozoan commonly found in soil, dust, and freshwater. Different strains of Pseudomonas aeruginosa are common culprits of inflammation and infection as seen with contact lens induced acute red eye (CLARE) reactions and ulcerative keratitis. Contact lens-induced peripheral ulcers (CLPU) are non-infectious peripheral corneal ulcers with infiltrates that must be differentiated from ulcerative keratitis. Giant papillary conjunctivitis (GPC) is a complication with a multifactorial etiology and a strong immunological component. Tear film debris can be associated with mucin balls and contact lens deposits. Proper fitting and follow-up of contact lenses is important to reduce the incidence of many contact lens complications, such as superior epitheal arcuate lesion (SEAL), corneal compression ring (CCR), and CL-SLK. Superficial punctate keratitis (SPK) is very common in contact lens wearers. It may be secondary to many things, including dry eye, solution hypersensitivity, poor fitting lenses, or inadequate oxygen supply to the cornea. The purpose of this literature review is to identify hydrogel contact lens complications, their causes, and management in order to better educate patients about a particular hydrogel contact lens complication. A patient educational CD was developed to allow the patient to take home printed educational material about their contact lens complication.
Thoroughly revised and updated, this popular book provides a comprehensive yet easy to read guide to modern contact lens practice. Beautifully re-designed in a clean, contemporary layout, this second edition presents relevant and up-to-date information in a systematic manner, with a logical flow of subject matter from front to back. This book wonderfully captures the ‘middle ground’ in the contact lens field ... somewhere between a dense research-based tome and a basic fitting guide. As such, it is ideally suited for both students and general eye care practitioners who require a practical, accessible and uncluttered account of the contact lens field. Outlines a rational clinical approach to modern contact lens fitting - practical advice for the clinic and the classroom Logical structure and systematic layout, with relevant chapters grouped into coherent sections for easy reference Up-to-date for accurate information Chapters are contextualised through cross-referencing - helping to reflect the relative importance of different topics Provides an 'historical time line' of contact lens development and explains the current global situation Explains how contact lenses are fabricated, designed, manufactured and measured Reviews the scientific principles that underpin the clinical application of contact lenses New chapter on daily disposable contact lenses. Contributing authors comprising optometrists, ophthalmologists, dispensing opticians, industry experts, researchers and clinicians – all of whom are true international leaders in their sub-specialty areas. Many new line diagrams and clinical photographs to illustrate, inform and explain the concepts outlined in the text. Special consideration is given to the most popular lens replacement systems – daily, two-weekly and monthly. Extensive appendices to assist chair-side decision making in everyday practice. Efron Grading Scales for Contact Lens Complications. Evidence-based approach with numerous up-to-date references at the end of each chapter.
