Being diagnosed with keratoconus can feel overwhelming – for patients and often for their loved ones too. At Vision Care Clinic (VCC), we understand how worrying it can be to feel your vision changing or to receive a new diagnosis that sounds unfamiliar. Corneal Consultant, Mr Kieren Darcy, is a specialist in this field and supports people at every stage – from those newly diagnosed to individuals who have been managing the condition for many years.

What Is Keratoconus?

Keratoconus is a progressive eye condition that affects the cornea: the clear, dome-shaped window at the front of the eye. In keratoconus, the corneal tissue becomes thinner and weaker over time. As a result, it begins to bulge outward in a cone-like shape and thinning in places.

This irregular shape causes:

•               Blurry or distorted vision

•               Increased sensitivity to light

•               Difficulty with night driving

•               Frequent changes in glasses prescriptions

Because the cornea plays a key role in focusing light, even small changes to its shape can significantly affect vision.

What Causes Keratoconus?

The exact cause is not fully understood, but several factors are known to play a role:

•               Genetics: It can run in families.

•               Eye rubbing: Strongly associated with progression.

•               Allergies or atopic conditions: These may increase eye rubbing and inflammation.

•               Biomechanical weakness of the cornea: Making it more prone to thinning.

Keratoconus usually begins in the teenage years or early adulthood, but it can appear later in life as well.

A Diagnosis Can Be Frightening — We’re Here to Help

Many patients contact us if their optometrist suspects keratoconus or soon after diagnosis, as they feel an urgency to act quickly, due to the progressive nature of the dystrophy, especially in younger individuals, and this naturally creates anxiety.   Therefore, accurate diagnosis and monitoring using advanced corneal imaging is key.

Our specialist, Mr Kieren Darcy, has extensive experience identifying and managing keratoconus at all stages. He will guide each patient through their options, ensuring they feel informed and supported.

Early, precise assessment is important – but you are not alone, and effective stabilisation treatments are available.

Two Main Pathways of Keratoconus Care

Different treatments are suitable depending on whether the condition is early, progressing, or more advanced.

1. Stabilising the Cornea in Early or Progressive Keratoconus

Corneal Collagen Cross-Linking (CXL)

Corneal Cross-Linking is the gold-standard treatment for stopping keratoconus from getting worse.

What is CXL?

CXL strengthens the cornea by increasing the chemical “cross-links” between collagen fibres. This is achieved by:

1.             Applying vitamin B2 (riboflavin) eye drops

2.             Activating them with a controlled UV light

3.             Causing the collagen fibres to interlink more tightly, making the cornea firmer and more stable

The goal with this procedure is to stop progression; CXL doesn’t reverse keratoconus, it helps prevent further deterioration and preserves existing vision for the long term.

CAIRS (Corneal Allogenic Intrastromal Ring Segments)

If the cornea has already become too thin, standard CXL alone, may be too late. In these cases, CAIRS can offer a solution.

What is CAIRS?

CAIRS is a technique where donor corneal tissue is placed into precise channels within the patient’s cornea. These channels are created using a femtosecond laser.  The added tissue reinforces and strengthens weak areas, helps reshape the cornea, can improve stability and may reduce the corneal irregularity

It is a promising option for patients with more advanced thinning.

2. Improving Vision — Laser & Specialist Contact Lenses

Advanced Customised Laser Treatments

For some individuals, especially those whose keratoconus is stable or can be combined with CXL to lock in a regularisation, customised laser treatments can improve the regularity of the cornea, reduce visual distortion and improve the quality of vision.  In some cases, patients can experience a reduction in glasses dependence.

While not suitable for everyone, carefully selected patients can experience a significant improvement in clarity.

Specialist Contact Lenses

If keratoconus has stabilised, many patients achieve excellent vision with advanced contact lens designs. that vault over or correct the irregular cornea.

Mini-scleral lenses, vault over the irregular cornea and rest on the sclera, which is the white part of the front of the eye. Offering increased comfort and improved quality of vision.  Alternatively, customised lenses like EyePrintPro – made using a 3D impression of the eye are used if a patient can benefit from a  precise fit, to the cornea.

These lenses can provide crisp, stable vision even in cases where glasses are no longer effective.

Living with Keratoconus Today

Compared to a decade ago, the outlook for keratoconus patients has transformed. Today, individuals benefit from:

•               Earlier and more accurate diagnosis

•               Highly successful stabilisation treatments such as CXL and CAIRS

•               Modern options to regularise and improve corneal shape

•               Advanced specialist lenses to restore high-quality vision

With the right care plan, many patients maintain good vision and lead full, active lives without interruption.

Helpful Keratoconus Communities & Forums

Connecting with others can be invaluable. These UK patient-led communities offer support, shared experiences, and educational resources:

•               Keratoconus UK support Group (Facebook)

•               UK Keratoconus Self Help and Support Association (Facebook)

•               Keratoconus Support Group (Facebook)

•               Keratoconus GB Living with Keratoconus (Facebook)

We have no involvement or interest in any of the platform above, but may give reassurance, practical tips, and a sense of community for patients and families.
