Objective:
To describe a patient who developed contact-lens associated Fusarium sp. keratitis associated with use of sample kits of ReNu with MoistureLoc purchased after worldwide recall of the product from the market.
Methods:
The patient's history, clinical presentation, and laboratory workup were reviewed.
Results:
In April 2008, a 64-year-old woman with a 45-year history of contact lens wear presented with a large central corneal infiltrate after receiving empiric antibiotic treatment before referral. Corneal and contact lens cultures revealed Fusarium sp. The patient had been using sample kits of ReNu with MoistureLoc purchased from a dollar store to clean her lenses.
Conclusions:
Although a worldwide recall of ReNu with MoistureLoc occurred in May 2006, the product may still be obtained in discount stores through sale of professional sample kits. Patients with contact lens-associated keratitis should be questioned regarding specifics of their contact lens hygienic regimen.
Insights
Contact lens wearers using recalled ReNu with MoistureLoc solution, even from sample kits, can develop Fusarium keratitis. This highlights risks associated with using products obtained after market withdrawal.
Area of Science:
- Ophthalmology
- Infectious Diseases
Background:
- Contact lens wear is common, necessitating proper lens hygiene to prevent microbial keratitis.
- Fusarium keratitis is a serious fungal infection of the cornea, often associated with contact lens use.
Observation:
- A 64-year-old woman with a history of contact lens wear presented with a corneal infiltrate.
- The patient used sample kits of ReNu with MoistureLoc, a product previously recalled worldwide.
Findings:
- Cultures confirmed Fusarium sp. infection in both the cornea and on the contact lenses.
- The recalled contact lens solution was purchased from a discount store.
Implications:
- Recalled contact lens solutions, even in sample kit form, can remain available and pose infection risks.
- Thorough patient history regarding contact lens hygiene practices is crucial for diagnosing and managing keratitis.
