Which method is critical in the prevention of keratitis related to contact lenses?

Regular cleaning and disinfection of contact lenses is crucial for preventing keratitis, which is an inflammation of the cornea often associated with contact lens use. Maintaining proper hygiene for contact lenses helps to remove harmful bacteria, proteins, and debris that can accumulate on the lenses. These contaminants can lead to infections, including keratitis, if they enter the eye.

Using solutions specifically designed for cleaning and disinfecting lenses is essential, as these products help to kill microorganisms that may cause eye infections. Adhering to a strict cleaning regimen reduces the risk of pathogens making contact with the cornea and subsequently causing inflammation or infection.

Other practices, such as using contact lenses while swimming, wearing them for extended periods, or opting for cheaper alternatives, may compromise lens integrity or hygiene. Swimming with contact lenses can expose them to waterborne pathogens, while extended wear increases the risk of decreased oxygen availability and buildup of deposits, both of which contribute to higher incidences of keratitis.
