Approximately 25,000 Americans develop infectious keratitis annually. The annual incidence of microbial keratitis associated with contact lens use is approximately 2-4 infections per 10,000 users of soft contact lenses and 10-20 infections per 10,000 users of extended-wear contact lenses. Approximately 10% of these infections result in the loss of 2 or more lines of visual acuity. [3]
