[Infectious corneal complications of contact lenses].

Keratitis in general may be caused by a large variety of microorganisms. The wear of contact lenses, mainly of soft material, increases the risk of corneal infection particularly by pseudomonas and acanthamoeba. The clinical aspects, the diagnostic procedures and the treatments are considered. With any type of lenses, rules of hygiene must be observed avoiding a brief tapwater rinse in order to decrease the risk of infection.
