Private Corneal Cross-Linking Services at our Dublin and Galway Clinics
If you are experiencing problems with your vision, such as blurriness or sensitivity to light, you may need to be referred to an ophthalmologist at a hospital for diagnosis and treatment of keratoconus. Keratoconus is a condition that affects the cornea, which is the clear outer layer of the eye. It can cause the cornea to become thin and bulge into a cone-like shape, which can affect your vision and cause discomfort.
If you are referred to an ophthalmologist for keratoconus, they will conduct a series of tests to diagnose the condition and determine the best course of treatment. Treatment options for keratoconus may include prescription eyeglasses or contact lenses, or in some cases, surgery. One common surgery for keratoconus is corneal cross-linking, which involves strengthening the cornea by using a special solution and UV light.
It is important to get diagnosed and treated for keratoconus as early as possible to prevent the condition from worsening and causing further damage to your eyesight. Your ophthalmologist will work with you to create a personalised treatment plan and monitor your progress throughout the treatment period. With the right treatment, it is possible to improve your vision and prevent long-term damage to your eyes.

What is Keratoconus?
Keratoconus is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than its normal gradual curve. Keratoconus can cause substantial distortion of vision, with the patient seeing multiple images, or seeing streaking of objects, or experiencing sensitivity to light. It is typically diagnosed in the patient’s adolescent years and can be most severe between the ages of 20 and 40.
If affecting both eyes, the deterioration in vision can affect the patient’s ability to drive a car or read normal print. In most cases, corrective contact lenses fitted by a specialist are effective enough to allow the patient to continue to drive legally and function normally. Further progression of the disease may require surgery, for which several options are available, including intrastromal corneal ring segments, cross-linking and in 10-15% of cases, corneal transplantation.
Keratoconus affects around one person in a thousand. It seems to occur in populations throughout the world, although it is observed more frequently in certain ethnic groups, such as South Asians. Environmental and genetic factors are considered possible causes, but the exact cause is uncertain.
Symptoms of keratoconus

Loss of vision.
Double vision.
Blurry vision.
Eye strain.
Sensitivity to bright light.

Types of Keratoconus
Advanced keratoconus
In advanced stages of keratoconus, the cornea becomes significantly thin and irregular, resulting in severe visual impairment. Scarring may develop on the cornea, further impacting vision. RGP lenses or specialized contact lenses such as scleral lenses may be necessary for visual improvement. In some cases, corneal transplantation may be considered if vision cannot be adequately corrected with contact lenses.
Mild keratoconus
In the early stages, keratoconus may cause mild irregular astigmatism and slight corneal steepening. Visual symptoms may be minimal, and glasses or soft contact lenses may provide adequate correction.
Moderate keratoconus
As keratoconus progresses, corneal thinning and steepening become more noticeable. Visual symptoms, such as blurred or distorted vision, glare, and sensitivity to light, may worsen. Rigid gas permeable (RGP) contact lenses are often required for better vision correction.
Post-LASIK Ectasia
In some cases, keratoconus-like changes can occur after LASIK or other corneal refractive surgeries. This condition, known as post-LASIK ectasia, involves corneal thinning and bulging, leading to progressive visual deterioration.
Progressive keratoconus
The corneal thinning and bulging characteristic of the condition continue to worsen over time. In progressive keratoconus, the shape of the cornea becomes increasingly irregular, leading to worsening visual symptoms such as blurred or distorted vision, sensitivity to light, glare, and difficulty with night vision.
Corneal Collagen Cross-Linking
This is a technique which uses UV light and a photosensitiser to strengthen chemical bonds in the cornea. The goal of the treatment is to halt the progressive and irregular changes in corneal shape, which are known as ectasia. These ectatic changes are typically marked by corneal thinning and an increase in the anterior and/or posterior curvatures of the cornea, and often lead to high levels of myopia (short-sightedness) and astigmatism (abnormal curvature).
The most common form of ectasia is keratoconus. In the cornea, collagen cross-linking occurs naturally with aging. It has been hypothesized that this natural cross-linkage of collagen explains why keratoconus (corneal ectasia) often progresses most rapidly in adolescence or early adulthood but tends to stabilize in patients after middle-age
What can you expect during the procedure
This is a non-invasive outpatient procedure. Drops are applied to numb the surface of the eyes, so that your ophthalmologist can painlessly remove the outer layer of the cornea. Then
Vitamin B (riboflavin) medicine is applied, and UV light is directed at the cornea. The UV light activates the Vitamin B, which allows new bonds to "cross-link" between the collagen in your cornea.
After the procedure, your eye will be covered by a bandage, and you may need to use steroid and/or antibiotic drops
Please note that we do not offer an emergency service for eye health issues. If you have the following symptoms, you should call 112 or 999:
- Sudden or severe eye pain
- Loss of sight
- Lots of flashing lights
- Chemicals in your eye
- Severe eye trauma
