[Acanthamoeba keratitis after use of soft contact lenses--case report].

The case history of a 39-year patient suffering from a deep inflammation of cornea and not responding to conventional antibiotic treatment is presented. The patient was using soft contact lenses during the period of initial symptoms; moreover, he was bathing in thermal bathing pool. A cultivation examination of smears from the area of corneal defect revealed the presence of Acanthamoeba lugdunensis in combination with bacterial infection by Pseudomonas aeruginosa. The available data indicate that it is the first case of acanthamoeba karatitis (AK) after the application of contact lenses in Slovakia. A long-term local treatment with propamidin isethionate (Brolene gtt, ung.) resulted in healing up. The subsequent vision after 16 months since the initial symptoms proved to be 6/12 (0.5). The healing of the centrally localized defect changed the curvature of cornea with consequent hypermetropic shift. The defect completely corrected the patient's myopia (-8.5). The paper describes present possibilities of AK therapy.
