A mixed keratitis due to Acanthamoeba and Hartmannella species is reported. The patient was a soft contact lens wearer. Early diagnosis was achieved by polymerase chain reaction and culture. The pathogenic potential of the isolated amoebae was proven using cytotoxicity assays. The reported case underlines the difficulties in identifying a corneal amoebic infection. In our case, the early diagnosis of a mixed infection allowed a proper antiamoebic treatment in an early stage of infection. This may have been the reason of a successful outcome after therapy.
