How can patients prevent keratitis?

Maintaining good hygiene with contact lenses is crucial in preventing keratitis, an inflammation of the cornea that can result from microbial infections. When patients do not adhere to proper lens care protocols—such as washing hands before handling lenses, using the correct cleaning solutions, and storing them in appropriate cases—they increase the risk of introducing pathogens to the eye. Contaminated lenses can harbor bacteria, viruses, or fungi that lead to infections, making good hygiene practices vital.

Proper hygiene practices involve not only how lenses are cleaned and stored but also ensuring they are not worn past the recommended duration and replacing them as advised. These steps significantly lower the risk of keratitis by minimizing exposure to potential contaminants that thrive on improperly cared-for lenses.

While using eye drops can be beneficial for maintaining moisture or treating certain conditions, it does not specifically prevent keratitis associated with unsanitary lens practices. Similarly, wearing contact lenses overnight can actually increase the risk of keratitis, as it can limit oxygen supply to the cornea and promote bacterial growth. Reducing screen time may help prevent digital eye strain but does not address the risk factors associated with contact lens wear. Therefore, emphasizing good hygiene with contact lenses is the most effective preventive measure against keratitis.
