Contact lens problems can be categorized as follows: infectious, hypoxic/metabolic, toxic, mechanical, inflammatory, and dry eye (Table 5-10).
With the increased use of disposable lenses, better patient education, more convenient care systems, and the availability of more oxygen-permeable lens materials, serious eye infections from lens use have become less common. However, practitioners should be aware of unusual infections that can occur, such as Acanthamoeba, fungal keratitis, and Pseudomonas (Fig 5-16A). Diagnosis and treatment of corneal infections are covered in BCSC Section 8, External Disease and Cornea.
