Stem Cell Deficiency
Limbal Stem Cell Deficiency (LSCD) is a condition affecting the surface of the eye. It occurs when the stem cells located at the limbus, the border between the cornea and the white part of the eye, become damaged or depleted. These specialised stem cells are essential for maintaining a healthy, clear corneal surface.

Why It Matters
The surface of the eye relies on limbal stem cells to remain smooth, clear and comfortable. When these cells are lost or damaged, vision can become unstable and the eye may struggle to heal properly.
What is Limbal Cell Deficiency?
Limbal Stem Cell Deficiency (LSCD) is a condition affecting the surface of the eye, specifically the cornea, the clear front layer responsible for focusing light. It occurs when the limbal stem cells, located at the edge of the cornea, become damaged or depleted. These cells play a vital role in continually renewing and repairing the corneal surface.
When limbal stem cells are not functioning properly, the eye cannot maintain a healthy, smooth cornea. As a result, the surface may become unstable, irritated or scarred, leading to symptoms such as blurred vision, redness, discomfort and sensitivity to light.
LSCD can affect one or both eyes and may develop gradually or suddenly depending on the cause. It is often linked to injury, inflammation, infection, surgery or long-term ocular surface disease. Because the condition affects the eye’s ability to heal itself, early diagnosis by a corneal specialist is important to protect vision and prevent progression.
At Centre for Sight, we use advanced diagnostic technology to assess the corneal surface and determine whether limbal stem cell function is impaired, allowing treatment to be tailored to each patient’s needs.

What are the Symptoms of Limbal Stem Cell Deficiency?
Symptoms of limbal stem cell deficiency can develop gradually and may initially resemble dry eye or surface irritation. Because the condition affects the eye’s ability to repair itself, symptoms often persist despite standard treatments. If ongoing discomfort, redness or vision changes occur, specialist assessment is important to identify the underlying cause and begin appropriate management.
Symptoms of limbal cell deficiency include:
Persistent eye redness
The eye may appear constantly bloodshot due to surface irritation and inflammation.
Blurred or fluctuating vision
Vision may vary throughout the day as the corneal surface becomes irregular or unstable.
Eye discomfort or pain
Patients often describe burning, stinging or a gritty sensation, similar to having something in the eye.
Light sensitivity
Bright light may feel uncomfortable or painful, especially if the corneal surface is damaged.
Excessive watering
The eye may produce more tears in response to surface irritation.
Poor healing of the eye surface
Minor injuries or irritation may take longer than usual to heal.
What Causes Limbal Stem Cell Deficiency?
Limbal Stem Cell Deficiency (LSCD) develops when the specialised stem cells at the edge of the cornea become damaged or are no longer able to function properly. These cells are essential for continuously renewing and repairing the surface of the eye. LSCD most commonly occurs after significant injury to the eye, such as chemical or thermal burns, but it can also develop gradually due to chronic inflammation, severe dry eye disease, autoimmune conditions or recurrent infections. In some cases, repeated eye surgeries or long-term contact lens wear may place stress on the limbal area and contribute to stem cell damage. Rare congenital or genetic conditions can also affect limbal stem cell function from birth. When these cells are compromised, the cornea loses its ability to heal and maintain clarity, which can lead to ongoing irritation, inflammation and visual disturbance. Early specialist assessment is important to identify the cause and prevent progression.
Diagnosis & Assessment
Early diagnosis of limbal stem cell deficiency is important to protect the surface of the eye and prevent long-term damage. Because symptoms can resemble other eye surface conditions, a detailed specialist assessment is needed to confirm the diagnosis and identify the underlying cause.

Treatment Options
Treatment for limbal stem cell deficiency focuses on restoring a healthy eye surface, relieving symptoms and protecting vision. The most suitable approach depends on the cause, severity and whether one or both eyes are affected. Our specialists tailor treatment to each patient to stabilise the surface of the eye and support long-term healing.
Medical Management
In milder or early cases, treatment may involve medicated eye drops, lubricants and anti-inflammatory therapies to improve the ocular surface environment. Managing underlying conditions such as dry eye, infection or autoimmune disease is often essential to reduce irritation and allow the eye to heal more effectively.
Protective Surface Therapies
Specialist treatments may be recommended to protect and support the cornea while it recovers. These can include therapeutic contact lenses, amniotic membrane treatments or surface-healing therapies designed to stabilise the eye and reduce discomfort. These approaches help create the right conditions for regeneration of healthy surface cells.
Stem Cell Reconstruction Procedures
For more advanced cases, surgical treatment may be needed to restore limbal stem cell function. This can involve transplanting healthy stem cells from another part of the eye or from a donor source to rebuild the damaged surface. These advanced procedures are performed by corneal specialists and are designed to improve comfort, restore clarity and prevent further deterioration.

Katie Piper and Limbal Cell Deficiency
Katie Piper was blinded in her left eye from a serious chemical injury. She underwent Ex-vivo limbal stem cell transplantation at Centre for Sight to repair the damage to the area on the front of the eye called the Limbus. It was the first stage in helping to restore her sight.
Since her procedure, Katie’s left eye is less angry and no longer intensely red. Her cornea has cleared significantly and she has experienced an improvement in her sight. You can read more about her story here.
Patient Success Stories
Such great care and service here. I had a household accident last week and came to get my eye looked at, which they went out of their way to accomodate on the same morning of ringing. The team is amazing, the admin, nurses, and consultant were really kind and caring. The follow up care has also been great with calls after a week to check how I’m getting on. Everyone has been so warm and friendly, a huge heartfelt thank you!

The best decision ever! My eye treatment at Centre for Sight has changed my life and enhanced my confidence. Having trifocal lenses implanted by Mr Sheraz Daya has restored my eyesight and I no longer need to use any lenses for reading, driving or any other activities.
From my first encounter with Mr Daya and his team at Centre for Sight, I felt most reassured that I was getting a very professional opinion and treatment. The day of the procedure was made much easier by the comforting support provided to me by Dr Espinosa whilst Mr Daya was performing my eye surgery. Overall, a fantastic experience and a great result.

Limbal Stem Cell Deficiency FAQs
Below are answers to common questions about limbal stem cell deficiency to help you understand the condition, its impact on vision, and when specialist care may be needed.
Is limbal stem cell deficiency permanent?
Not always. In some cases, mild or early LSCD can improve when the underlying cause is treated. More advanced cases may require specialist procedures to restore the eye surface, but effective treatments are available.
Can limbal stem cell deficiency affect both eyes?
Yes. LSCD can affect one or both eyes depending on the cause. Injuries or infections often affect one eye, while systemic or inflammatory conditions may affect both.
Is limbal stem cell deficiency painful?
It can be. Many patients experience irritation, burning or a gritty sensation because the corneal surface becomes unstable and sensitive. Pain levels vary depending on severity.
Can LSCD be mistaken for dry eye?
Yes. Early limbal stem cell deficiency can resemble dry eye disease because both can cause redness, irritation and blurred vision. Specialist examination is needed to distinguish between them.
