Contact lens wear by hospital health care staff: is there cause for concern?
Microbial keratitis can occur in association with contact lens wear. The absolute risk of infection is low but may be enhanced as a consequence of increased exposure to potentially pathogenic microbes in a hospital setting. There is variation in risk depending on type of lens worn and its modality of use. Extended-wear lenses carry the greatest risk. Pseudomonas aeruginosa and Acanthamoeba are causes of potentially devastating ocular infections in contact lens wearers. The risk of these infections could be reduced by fastidious hygiene practice. Hydrogen peroxide disinfection is recommended when a storage case is included in the care regimen. This should be cleaned thoroughly and dried prior to disinfection and never exposed to tap water. Daily wear of one-day 'disposable' soft contact lenses or use of rigid gas permeable lenses is recommended for hospital staff. Contact lenses should be removed immediately and discarded or disinfected if the eye becomes contaminated and/or use of an eyewash is required.
