Contact lens-related keratitis is an infection or inflammation of the cornea linked to contact lens wear.
How lens-related keratitis develops
Bacteria, fungi, or other germs can enter the eye if lenses are not cleaned or used correctly. Even sterile inflammation without infection can occur when lenses do not fit well or are over-worn.
- Symptoms include pain, redness, watering, and sensitivity to light
- Vision may become blurred, especially if a white spot forms on the cornea
- Sleeping in lenses and swimming while wearing them increase risk
- Poor hygiene, such as topping up solution, also raises infection chances
Urgent steps to protect sight
Contact lens-related keratitis is an emergency because scarring can permanently affect vision. Quick action and stopping lens use straight away greatly improve outcomes.
- Remove lenses immediately if the eye becomes painful or red
- Seek same-day eye care, ideally at an emergency eye clinic
- Bring lenses, case, and solutions so they can be tested if needed
- Only restart lens wear when your specialist confirms it is safe
