Contact lens-related keratitis is on the rise, according to a recent CDC report. Approximately 41 million US individuals wear contact lenses, and almost 99% of contact lens wearers surveyed reported at least one behavior that puts them at risk for an eye infection. Keratitis (cornea inflammation) is a common eye infection that can be caused by viruses, bacteria, fungi, or parasites that enter the eyes as a result of poor contact lens hygiene.Contact lenses are classified as medical devices and regulated by the FDA. Between 2005 and 2015, there were a total of 1075 contact-lens related adverse events reported, of which:
213 (19.8%) discussed patients with corneal scars, decreased vision, and corneal transplant surgery.270 (25.1%) discussed risk factors for corneal infections, including sleeping in contact lenses, extended wear, using expired lenses or products, storing lenses in tap water, or wearing lenses while swimming.More than 10% demonstrated that adverse events resulted in emergency department visits or immediate care.
