HEMA-contact lens and HEMA-dressing lens-damage to the eye (author's transl)]

3 cases in which HEMA-contact lens, and 2 cases in which HEMA-dressing lens caused corneal damage were analyzed with regard to symptomatology, etiology and sequence of events. Hyperemia of the limbus is the main symptom. Avoidable causes are exaggerated tightness, overwearing, storing up of proteins, rough surface, and incompatibility of soft-lens solutions. Irreversible and largely resistant to therapy is, damage resulting from the synthetic itself.
