To our knowledge, this is the first case report of a corneal infection caused by A. xylosoxidans, which was isolated and identified from a contact lens, case, and solution using culture and PCR technique as well the first description of ocular surface disease resolution after the treatment with topical polymyxin B or trimethoprim. A. xylosoxidans should be considered as uncommon but potential pathogen capable of infectious spread through contaminated contact lens solution.
SIGNIFICANCE
Standardized guidelines that are clinically practical are needed to assist the prescriber in minimizing the risk of conveying infection through multiuse diagnostic contact lens use and reuse.
Contact lens prescribers face the specter of transferring potential pathogens from one patient to another when reusing diagnostic (trial) contact lenses on multiple patients because infectious organisms have been recovered from worn contact lenses, although there is no evidence of transmission through this mechanism. These pathogens can be introduced into the system from one patient to another, or they may be introduced by clinician lens handling, storage, or both. These pathogens can cause acute or chronic systemic or ocular infection that can lead to significant morbidity (temporary or permanent) that includes vision loss.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
