Abstract
-
PURPOSE: To report 4 cases of Acanthamoeba keratitis related to orthokeratology lens overnight wear.
METHODS
Four patients had histories of overnight orthkeratology lens wear of 10 months to 3 years when they presented with corneal ulcers.
RESULTS
The organism isolated by corneal scraping was Aanthamoeba. The patients were treated with polyhexamethylene biguanide (PHMB), and chlorhexidine, resulting in a resolution of ocular inflammation.
CONCLUSION
The risk of Acanthamoeba keratitis as a potential complication of overnight orthkeratology should be considered.
