If you're 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're 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's 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's possible to improve your vision and prevent long-term damage to your eyes.

What is Kertoconus?
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.
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.
