The most common infection related to contact lens use is keratitis, an infection of the cornea (the clear, round dome covering the eye's iris and pupil). Keratitis can be caused by many things, including herpes, bacteria, fungus and microbes.
Symptoms of keratitis may include:
Keratitis can sometimes cause serious vision loss or even blindness, so it is important to see an optometrist if you are experiencing the above symptoms.
Keratitis is most commonly related to contact lens use, but can be caused by various factors including herpes, bacteria, fungus and microbes. It is not transmitted from person to person, but fungal keratitis is more common in warmer climates. Risk factors for contact lens-related keratitis include use of extended-wear lenses, reduced tear exchange under the lens, environmental factors, and poor hygiene.
Your optometrist will examine your eyes and may use special diagnostic tools to determine the exact cause of the keratitis. Early diagnosis is crucial as keratitis can lead to serious vision complications if left untreated.
Fungal keratitis is treated with topical and oral antifungal medications. Patients who do not respond to medical treatment may require eye surgery, possibly including a corneal transplant. The best way to avoid eye infections due to wearing contact lenses is to follow proper lens care guidelines as recommended by your optometrist.
