[Healed (?) amoebic keratitis].

Acanthamoeba keratitis was seen in two contact-lens wearers. In both cases, this finding was verified by microbiological examination of conjunctival swabs and of the lens solution. One patient had perforating keratoplasty. While neither vital amoebae nor cysts could be detected in the host corneal explant, immunohistochemical examination revealed fluorescence-positive fragments which probably correspond to incomplete cycstic walls.
