Purpose:
To present four cases of Acanthamoeba keratitis as a complication of orthokeratology.
Design:
Observational case report.
Methods:
Four patients with Acanthamoeba keratitis had histories of overnight orthokeratology lens wear of 6 months to 2 years.
Results:
Three cases were diagnosed with Acanthamoeba keratitis by corneal scraping and one by confocal microscopy examination. The patients were treated with chlorhexidine, metronidazole, and neomycin sulfate, resulting in a rapid resolution of ocular inflammation.
Conclusion:
Overnight wear of orthokeratology lenses may induce Acanthamoeba keratitis.
