Achromobacter xylosoxidans keratitis masquerading as recurrent erosion after LASIK.

PURPOSE

To describe the clinical stages and management of Achromobacter xylosoxidans keratitis with post-LASIK epithelial ingrowth in two patients.

METHODS

Retrospective chart review.

RESULTS

Both patients had been treated with topical antibiotics and corticosteroids for several weeks prior to presentation. Examination at presentation revealed significant areas of epithelial ingrowth without signs of acute inflammation, prompting an erroneous initial diagnosis of recurrent corneal erosion. A corneal infiltrate was eventually observed and A. xylosoxidans was cultured from both patients. Clinical resolution occurred with treatment consisting of topical fortified antibiotics. In one patient, the flap was lifted to obtain cultures and irrigate the stromal bed with fortified antibiotics.

CONCLUSIONS

Post-LASIK epithelial ingrowth may have served as a risk factor for A. xylosoxidans infection. Classic signs of infectious keratitis were absent, delaying the diagnosis. Three clinical stages described herein may assist the clinician with diagnosis and customized management obviating the need for penetrating keratoplasty.
