Normally, the cornea is clear and transparent, allowing light to pass through without obstruction and focus accurately on the retina. Since the cornea is responsible for bending light, its clarity is essential for sharp vision.

Corneal scarring occurs when the cornea develops an opacity or irregularity, preventing light from focusing properly. Patients often describe vision as dim, blurred, or cloudy, similar to looking through a fogged-up window.

Not every corneal scar impacts vision. Scars on the peripheral cornea may cause little to no disturbance, while scars in the central cornea, especially over the pupil, can cause significant vision loss.

Corneal scarring can develop due to trauma, improper contact lens use, eye diseases, degenerations, or even systemic health conditions. Below are some of the most common causes:

• Improper contact lens wear – Misuse of contact lenses, such as poor cleaning habits, failure to replace lenses on time, inadequate hand hygiene, or sleeping in lenses, can increase the risk of corneal scarring.
• Corneal abrasion (scratch) or eye injury – While minor scratches often heal without lasting effects, deeper injuries to the cornea may leave permanent scars.
• Keratitis (corneal infection) – Inflammation of the cornea caused by viral, bacterial, or fungal infections. This may occur after trauma or due to improper contact lens hygiene.
• Keratoconus – A progressive eye condition where the cornea thins and bulges outward, often resulting in scarring over time.
• Corneal dystrophies – Hereditary disorders that change the cornea’s structure and may lead to scarring.
• Ocular herpes or herpes zoster – Viral eye infections that create sores on the cornea, which can eventually turn into permanent scarring.
• Stevens-Johnson Syndrome (SJS) – A severe condition that causes painful blisters and lesions on the skin and mucous membranes, often leading to serious eye complications, including scarring.
• Severe dry eye disease – Lack of proper moisture and lubrication on the eye’s surface increases friction and irritation, which can result in corneal scarring over time.

A variety of treatment options for corneal scars exist, depending on their severity and location. For mild peripheral scars, glasses or soft contact lenses may be sufficient. In cases of mild to severe scarring, specialty contact lenses are often the most effective solution. For more advanced scarring, a corneal transplant may be recommended. Additionally, laser procedures such as phototherapeutic keratectomy (PTK) can remove shallow scars, while deeper scars may require surgical intervention.

The right treatment plan for a corneal scar depends not only on its size, depth, and location, but also on the patient’s lifestyle and vision goals. At The Raleigh Contact Lens Institute, we perform detailed examinations for corneal scarring and allow ample time for one-on-one discussions to address every concern.

Because corneal scars vary widely, having expertise in this area is crucial. Our practice is equipped with advanced technology and extensive experience to deliver the best possible outcomes. Among the most effective treatment options, RGP (rigid gas permeable) lenses and scleral lenses provide excellent vision correction for scarred corneas. These specialty lenses are designed to improve clarity, comfort, and long-term eye health.

Our doctors carefully evaluate each patient’s situation, perform a thorough eye examination, and provide personalized recommendations.
