Aspergillus fumigatus Keratitis After Laser In Situ Keratomileusis

This report is the first description of Aspergillus keratitis after LASIK. We hypothesize that the infection became established on the stromal bed during surgery and led to melting, anteriorly through the flap and posteriorly through the stroma. Diagnosis was made by a corneal biopsy and inoculation of a wide array of media. This case demonstrates the need to consider atypical organisms, including fungi, in the differential diagnosis of post-LASIK infections when there is no response to therapy and highlights the role of corneal biopsy and flap lifting in the diagnosis of this condition.
