A multi-country outbreak of fungal keratitis associated with a brand of contact lens solution: the Hong Kong experience.

Objectives: Starting in mid-2005, an increase in fungal keratitis caused by Fusarium spp was observed among contact lens wearers in Hong Kong, Singapore, and the USA. The objective of this study was to describe the outbreak and to determine any association with the use of Bausch & Lomb (B&L) ReNu contact lens solution.

Methods: We defined a case as a disposable contact lens user with ophthalmologist-diagnosed keratitis and a positive culture of Fusarium spp reported to the Department of Health from January 1, 2005 to May 31, 2006.
