[Contact lens complications : Diagnosis and treatment].

Contact lens complications are all pathological alterations of the eyes caused by wearing contact lenses. Clinical manifestations particularly affect the cornea and conjunctiva. A differentiation is made between undesired manifestations and disease conditions that at least temporarily make the further wearing of contact lenses impossible. The decisive factor is that for every irritation of the anterior segment of the eye the possibility of contact lens complications is considered and investigated. This article describes the most important contact lens types, the physiology and pathology of corneal metabolism, clinical manifestations and the corresponding treatment.
