A CDC report on three cases of fungal keratitis following laser eye surgery at a New York ophthalmology clinic highlights critical infection control failures. For overseas medical aesthetics buyers and distributors, this underscores the importance of rigorous sterilization protocols and device maintenance in clinical settings, especially when sourcing equipment or consumables for aesthetic laser procedures.
Outbreak details
Three patients developed Purpureocillium lilacinum infections after surgery at a single clinic, resulting in vision loss for all and one requiring corneal transplantation. The New York City Health Department investigation found multiple deficiencies in infection prevention and control practices, including incomplete instrument sterilization logs, use of expired topical medications, and exposure to non-sterile water from cool-mist humidifiers in the procedure room.
Device contamination
Laboratory testing identified P. lilacinum DNA in the tubing of a surgical device. The CDC advises against using cool-mist humidifiers in healthcare facilities. After cases were reported in December 2024, surgeries were suspended and resumed in January 2025, with no further cases after implementing recommended IPC measures.
Clinical implications
The report notes that P. lilacinum infections are often associated with soft contact lens use, eye trauma, eye surgery, and immunosuppression. Authors emphasize that because P. lilacinum causes drug-resistant keratitis and detection rates are increasing, it should be considered as a potential cause of infection after eye surgery, even before definitive culture identification.
Sourcing context
For aesthetic clinics performing laser eye procedures or similar treatments, this outbreak reinforces the need for strict infection control protocols. Buyers should verify that suppliers of surgical devices, consumables, and sterilization equipment comply with international IPC standards. Regular audits of sterilization logs and avoidance of expired medications are essential to prevent such outbreaks.
