Abstract. A 24-year-old female was referred to us for corneal ulcer in her right eye. She had been wearing soft contact lens over years. She had pain in her right eye 2 weeks before and was diagnosed with suspected dendritic keratitis. Ensuing treatments were futile. Her corrected visual acuity was 0.06 right and 1.2 left. Her right cornea showed erosion and disc-shaped opacity in its center. While the findings were suggestive of acanthamoeba keratitis,instillation of fluconazole and miconazole in addition to repeated debridements was ineffective. Four months after her initial visit,acanthamoeba was cultured from the contact lens and the storage container. Acanthamoeba DNA was isolated from the corneal scrapings processed by polymerase chain reaction(PCR). Eventual cure was obtained after additional instillation of chlorhexidine and polyhexamethylene biguanide(PHMB)that are claimed to be effective for acanthamoeba keratitis.
