Keratoconus is an eye condition where the normally round, dome-shaped cornea (the clear front surface of the eye) becomes thin and gradually bulges into a cone-like shape. This irregular shape affects how light enters the eye, leading to distorted or blurred vision.

Keratoconus usually begins in the teenage years or early 20s, and can progress over time. While it affects people differently, early diagnosis and ongoing management are key to preserving clear vision and preventing complications.

Symptoms of Keratoconus

The signs can vary, but common symptoms include:

• Blurred or distorted vision
• Frequent changes in glasses prescriptions
• Glare and halos around lights
• Increased sensitivity to light
• Ghosting or double vision in one eye
• Difficulty seeing clearly at night

Because keratoconus can progress at different rates, regular monitoring is essential.

How We Diagnose Keratoconus

At Illume Eye Care, we use advanced imaging technology to assess the shape and thickness of your cornea. Corneal topography and anterior segment OCT (a 3D map of the cornea) helps us detect keratoconus early — sometimes before noticeable symptoms occur. Early diagnosis means more options for treatment and better long-term outcomes.

Treatment Options

Treatment depends on the severity of the condition and your individual needs. Options include:

• Glasses or Soft Contact Lenses – useful in the early stages when the corneal shape is only mildly irregular.
• Specialist Contact Lenses – such as rigid gas permeable (RGP), hybrid, or scleral lenses, which create a smooth optical surface to restore clear vision.
• Corneal Collagen Cross-Linking (CXL) – a hospital-based procedure that can help strengthen the cornea and slow or stop progression of keratoconus.
  Advanced Surgical Options – in more advanced cases, corneal transplants or intracorneal ring segments may be recommended by your ophthalmologist.

At Illume, we specialise in fitting scleral and custom-designed contact lenses that provide exceptional comfort and clarity for patients with keratoconus.

Living with Keratoconus

With today’s treatments, most people with keratoconus can enjoy excellent vision and lead active lives. The key is ongoing monitoring, specialist contact lens fitting where needed, and early intervention to prevent progression.

We’ll work closely with you — and, when required, your ophthalmologist — to create a management plan tailored to your eyes.
