What Is Keratitis and How It Affects the Cornea

Keratitis is an inflammation of the cornea, the clear, curved layer at the front of your eye that protects the iris and pupil. This condition can occur with or without an infection.

Infectious keratitis is caused by bacteria, viruses, fungi, or parasites, while non-infectious keratitis may result from minor injuries, such as wearing contact lenses too long or getting a foreign object in the eye. Sometimes, it can also develop in people with autoimmune diseases like rheumatoid arthritis.

If left untreated, keratitis can lead to serious complications, including corneal ulcers or vision loss. However, with prompt attention and treatment, most cases can be managed effectively, protecting your eyesight. If you notice any unusual redness, discomfort, or changes in your vision, you must see a doctor immediately to avoid potential long-term damage.

Common Symptoms and Warning Signs of Keratitis

Keratitis can cause a range of symptoms that are often noticeable and uncomfortable. If you suspect you have keratitis, look out for the following signs:

Eye Redness: The affected eye may appear bloodshot or irritated.
Eye Pain: Discomfort ranging from mild irritation to severe pain.
Gritty Sensation: A feeling like something is stuck in your eye.
Watery Eyes: Excessive tearing or discharge, sometimes yellow or green.
Difficulty Opening The Eyelid: Pain or stickiness may make it hard to open the eye.
Blurry Or Cloudy Vision: The inflammation affects the cornea, making sight less clear.
Sensitivity To Light (Photophobia): Bright lights may cause discomfort or pain.
Swelling: In some cases, the eye or eyelid may swell.

These symptoms can develop quickly and may worsen without treatment. If you experience any of these signs, seeing an eye doctor as soon as possible is essential to prevent complications and protect your vision.

Causes and Risk Factors of Keratitis

Keratitis, or inflammation of the cornea, can have both infectious and non-infectious causes. Understanding these can help prevent and manage the condition effectively.

Non-Infectious Causes

Non-infectious keratitis is often triggered by physical or environmental factors that irritate or damage the cornea. Common causes include:

Contact Lenses: Prolonged or improper use of contact lenses, such as wearing them while sleeping, can scratch or dry out the cornea.
Eye Injuries: Scratches from foreign objects or accidents during surgery can lead to corneal inflammation.
Dry Eyes: Reduced tear production can increase the risk of keratitis.
UV Exposure: Photokeratitis, or sunburn of the cornea, can result from excessive UV light exposure, such as sunlight, tanning beds, or watching solar eclipses without protection.
Eyelid Conditions: Issues like entropion (inward-turning eyelids) can cause the eyelashes to scrape the eye’s surface.
Autoimmune Disorders: Conditions like Sjögren’s syndrome or rheumatoid arthritis may cause dryness, leading to inflammation.
Vitamin A Deficiency: Lack of this essential nutrient can weaken the cornea, increasing the risk.

Infectious Causes

Infectious keratitis occurs when bacteria, viruses, fungi, or parasites invade the cornea. Key causes include:

Bacteria: The most common infectious agents, often associated with contaminated contact lenses or solutions.
Viruses: Herpes simplex and shingles (herpes zoster) can cause recurring keratitis.
Fungi: Injuries involving plant material or dirty lenses can introduce fungi to the eye.
Parasites: Amoebas in lakes, rivers, hot tubs, or tap water can cause acanthamoeba keratitis, particularly in people who swim with contact lenses.

Each type of keratitis requires specific care. If you experience symptoms, seek medical attention promptly to prevent complications.

Treatment Options for Keratitis

The treatment for keratitis depends on its cause and severity. Early and proper care is essential to prevent complications and protect your vision.

Infectious Keratitis

Treatments for infectious keratitis focus on addressing the specific organism causing the inflammation:

Bacterial Keratitis: Treated with antibiotic eye drops, often administered multiple times daily. Severe infections may require oral antibiotics or more frequent applications, including at night.
Fungal Keratitis: This condition requires antifungal eye drops and, in some cases, oral antifungal medication. Treatment may take several weeks to months.
Viral Keratitis: Antiviral eye drops or oral medications are prescribed to manage infections caused by viruses like herpes simplex. Artificial tears can help relieve symptoms. Since viral keratitis has no cure, it may recur, and some patients need ongoing antiviral medication.
Parasitic (Acanthamoeba) Keratitis: Treated with antiparasitic eye drops. However, these infections can resist medications, requiring prolonged treatment over several months. In severe cases, a corneal transplant may be necessary.

If medication fails to resolve the infection or if there is significant corneal damage, corneal transplant surgery may be recommended.

Non-Infectious Keratitis

Artificial tears, eye ointments, or cold compresses can soothe discomfort for mild cases. An ophthalmologist may prescribe topical steroid eye drops to reduce swelling if symptoms are severe.

Important Care Tips

Stop wearing contact lenses immediately if you have symptoms of keratitis.
Complete the full course of prescribed medications, even if symptoms improve.
Visit your eye doctor if symptoms worsen, your vision becomes blurry, or redness and swelling increase.

Prompt and proper treatment can effectively manage keratitis, ensuring a full recovery and protecting your eyesight.

Types of Keratitis and Recommended Treatments

Type of Keratitis	Main Cause	Treatment Approach
Bacterial Keratitis	Bacteria from contact lenses or contaminated water	Antibiotic eye drops or oral antibiotics
Fungal Keratitis	Fungi from soil, plants, or contact lenses	Antifungal drops or oral antifungal medication
Viral Keratitis	Herpes simplex or shingles virus	Antiviral drops or oral antivirals; ongoing care for recurrences
Parasitic (Acanthamoeba)	Amoebas from water or poor lens hygiene	Antiparasitic drops; may require long-term treatment
Non-Infectious Keratitis	Dry eyes, UV exposure, or injury	Artificial tears, steroid drops, or lifestyle adjustments

How to Prevent Keratitis and Protect Eye Health

Keratitis can often be prevented by following good eye care habits, particularly if you wear contact lenses or are at risk of eye injuries or infections. Here are some essential steps to minimise your risk:

Contact Lens Care

Always wash and dry your hands thoroughly before handling contact lenses.
Remove contact lenses before sleeping, swimming, or showering.
Use a recommended cleaning solution to disinfect and store your lenses; never use tap water or saliva.
Clean and replace your contact lens case every 3–6 months, allowing it to air dry between uses.
Replace your lenses per your doctor’s schedule, and avoid wearing expired or damaged ones.
Avoid mixing old and new cleaning solutions in the case.
Have a backup pair of glasses when your lenses cannot be worn safely.

General Eye Care

Wash your hands with soap and water before touching your eyes.
Wear protective goggles or glasses when working with plants, chemicals, or machinery.
Protect your eyes from bright sunlight by wearing sunglasses with UV protection.
Use artificial tears if you have dry eyes or a condition that affects tear production.
Ensure your diet includes vitamin A-rich foods like eggs and dairy, which support eye health.

Preventing Infections

Avoid touching your eyes if you have cold sores or herpes blisters.
Only use eye drops recommended or prescribed by your doctor.
Wash your hands frequently to reduce the spread of viruses.
Keep allergens away to prevent irritation.

Regular check-ups with an eye doctor can also help detect any issues early, ensuring your eyes stay healthy and free from keratitis. Mobi Doctor can help you prevent and manage keratitis with expert online consultations, personalised advice, and effective treatment plans

Keratitis Treatment Online FAQs

Many mild or early keratitis symptoms can be initially assessed online, especially when symptoms involve eye redness, irritation, pain, blurred vision, or light sensitivity without severe vision loss. At Mobi Doctor, licensed EU doctors review your symptoms, contact lens history, and possible infection risks to help determine appropriate treatment or whether urgent in-person eye care is needed.

Keratitis is inflammation of the cornea, the clear front layer of the eye that helps focus vision and protect deeper eye structures. The condition may develop from bacterial, viral, fungal, or parasitic infections, but it can also happen after eye injuries, dry eyes, or prolonged contact lens use.

Common keratitis symptoms include eye redness, pain, blurred vision, excessive tearing, sensitivity to light, and the feeling that something is stuck in the eye. Some people also develop swelling, discharge, difficulty opening the eye, or worsening discomfort when wearing contact lenses.

Contact lenses are one of the most common causes of infectious keratitis, especially when lenses are worn too long, cleaned poorly, or exposed to contaminated water. Sleeping in contact lenses or swimming while wearing them increases the risk of corneal infection and inflammation.

Urgent medical attention is needed if keratitis symptoms include sudden vision changes, severe eye pain, worsening redness, pus-like discharge, or increasing sensitivity to light. Rapid treatment is important because untreated corneal infections can lead to corneal ulcers, scarring, or permanent vision loss.

Keratitis treatment depends on the underlying cause and severity of symptoms. Doctors may recommend antibiotic, antiviral, antifungal, or antiparasitic eye drops for infectious keratitis, while non-infectious cases may improve with lubricating eye drops, cold compresses, or anti-inflammatory treatment.

Eye pain and light sensitivity often happen because keratitis causes inflammation of the cornea, making the eye more sensitive to movement, bright light, and blinking. These symptoms may worsen quickly if infection or corneal irritation continues without treatment.

Dry eyes can increase the risk of keratitis because the tear film helps protect the cornea from irritation and infection. Reduced tear production, prolonged screen use, autoimmune conditions, or chronic eye dryness may leave the eye surface more vulnerable to inflammation and damage.

An online doctor can assess many non-emergency keratitis symptoms and help identify whether infection, dry eyes, contact lens irritation, or another eye condition may be contributing to symptoms. Mobi Doctor doctors may recommend urgent ophthalmology review, eye drops, or further investigation depending on symptom severity and vision changes.
