Abstract
The aim of this study was to report a severe case of mixed fungal and bacterial microbial keratitis following implantation of a self-retained cryopreserved amniotic membrane, PROKERA® SLIM (Bio-Tissue, Inc) in a patient with history of neurotrophic ulcer secondary to herpetic epithelial keratitis. Despite maximally tolerated topical and systemic therapy, the patient's eye continued to deteriorate and eventually required evisceration. PROKERA implantation might be associated with severe recalcitrant microbial keratitis. Caution is urged when considering implantation especially in monocular patients.
