Corneal Scarring: Causes, Symptoms, and Modern Treatment Options

Our eyes are delicate organs, and the cornea (the clear, dome-shaped front surface) plays a crucial role in focusing light and helping us see clearly. When the cornea is injured or affected by disease, it may develop scarring. Corneal scarring can block or distort light entering the eye, leading to blurred or cloudy vision. Fortunately, with advancements in eye care, effective treatment options are available to restore sight and protect long-term vision.

In this blog, we’ll explore the causes, symptoms, and modern treatment options for corneal scarring while answering common patient questions.

What is Corneal Scarring?

The cornea is made up of transparent tissue that must remain clear for sharp vision. When the cornea is damaged due to infection, injury, or other conditions, the healing process can sometimes leave scar tissue behind. This scar tissue disrupts corneal clarity, causing visual impairment.

While minor scars may not affect vision significantly, deeper or larger scars can cause major problems and may require medical or surgical treatment.

Causes of Corneal Scarring

Several conditions and injuries can lead to scarring of the cornea. Some of the most common causes include:

  • Infections – Severe eye infections such as bacterial keratitis, viral herpes simplex keratitis, or fungal keratitis can damage corneal tissue.
  • Corneal Ulcers – Untreated ulcers often leave behind permanent scars.
  • Eye Injuries – Trauma from accidents, scratches, or foreign objects can cause scarring during the healing process.
  • Contact Lens Misuse – Overuse, poor hygiene, or sleeping with lenses can increase the risk of corneal infections and scars.
  • Chronic Eye Conditions – Diseases such as keratoconus, severe dry eye, or autoimmune conditions (like Stevens-Johnson syndrome) can cause scarring.
  • Surgical Complications – Although rare, certain eye surgeries may result in corneal scarring if healing does not progress normally.

Key Insight: In India, corneal scarring remains one of the leading causes of preventable blindness, highlighting the importance of early diagnosis and treatment.

Symptoms of Corneal Scarring

The symptoms vary depending on the severity and location of the scar. Patients may experience:

  • Blurred or cloudy vision – Reduced clarity or “foggy” vision.
  • Eye pain or discomfort – Especially if scarring follows an infection or ulcer.
  • Light sensitivity (photophobia) – Bright light causes irritation or pain.
  • Glare or halos – Especially noticeable at night while driving.
  • Redness and swelling – Indicating ongoing irritation or inflammation.
  • Distorted vision – Straight lines may appear bent or wavy.

If you notice any of these symptoms, it’s important to seek professional eye care immediately.

Modern Treatment Options for Corneal Scarring

Thanks to advances in ophthalmology, patients with corneal scars have multiple treatment options. The choice depends on the depth, location, and extent of scarring.

1. Medications and Eye Drops

  • Antibiotics, antivirals, or antifungals are prescribed if scarring is due to an active or recent infection.
  • Steroid eye drops may help reduce inflammation and limit scar tissue formation.
  • Medications are most useful in the early stages or for preventing the worsening of scars.

2. Laser Treatments (PTK – Phototherapeutic Keratectomy)

  • PTK is a specialised laser procedure that removes superficial corneal scars and smoothens irregular surfaces.
  • It can improve vision significantly in cases of shallow scarring.
  • Recovery is usually quick, though multiple sessions may be needed.

3. Corneal Transplant Surgery

For deeper or more severe scars, surgery may be required:

  • Penetrating Keratoplasty (PKP): Full-thickness corneal transplant, replacing the damaged cornea with donor tissue.
  • Lamellar Keratoplasty (DALK/DSAEK/PDEK): Partial-thickness transplant, replacing only the affected corneal layers.
  • These surgeries can restore clear vision in advanced cases.

4. Advanced Options

  • Stem Cell Therapy: Research is underway to regenerate damaged corneal tissue.
  • Artificial Cornea (Keratoprosthesis): In extreme cases where transplants fail or are not possible.

Recovery After Corneal Scarring Treatment

  • Medication-based treatments typically improve symptoms in weeks.
  • PTK recovery may take a few days to weeks.
  • Corneal transplant recovery can take several months, with vision improving gradually.
  • Regular follow-up and aftercare are crucial to prevent complications.

Home Care and Prevention

While not all scars are preventable, many cases can be avoided with proper care:

  • Practice good eye hygiene – Wash your hands before touching your eyes or lenses.
  • Follow contact lens guidelines – Keep lenses clean and never wear them overnight.
  • Use protective eyewear – Safety glasses during sports, construction, or other risky activities.
  • Seek early treatment for eye infections or injuries – Delaying increases the risk of scarring.
  • Regular eye check-ups – Especially for people with diabetes, dry eyes, or autoimmune conditions.

FAQs About Corneal Scarring

Minor scars may fade over time, but most do not heal completely without treatment.

It depends on the treatment- weeks for medications, months for corneal transplant surgery.

Mild scars may not impact vision much, but significant scarring often requires surgical correction.

If you experience sudden vision changes, pain, or cloudy vision, seek immediate medical help.
