Keratoconus Care Clinic

Keratoconus Treatment in Brisbane, Booval, Wynnum, & Aspley

Your cornea — the transparent outer covering of your eye — is one of the most important components of your visual system. It is responsible for bending, or refracting, light entering your eye onto your retina. Keratoconus is a condition characterized by the thinning and bulging of the cornea. This abnormality interferes with incoming light and causes increasingly blurry, distorted vision.

If you have developed keratoconus or another corneal disorder, you need a knowledgeable, experienced eye doctor to manage it. The team of doctors at The Eye Health Centre has helped many individuals just like you monitor the disease and undergo treatment when necessary.

Understanding Keratoconus

To function properly, the cornea needs to have a round shape, similar to a basketball. Instead of maintaining a healthy round shape, a cornea with keratoconus thins and bulges into a more cone-like shape.

We do not completely understand what causes keratoconus. Some doctors believe there may be a genetic component, and if you have a parent with keratoconus, you are more likely to get it yourself. Other factors that have been linked to keratoconus include overexposure to sunlight; frequent, vigorous eye rubbing; and chronic eye irritation.

Symptoms

Every case of keratoconus is unique. Symptoms include the following:

  • Blurry or distorted vision at any distance
  • Sensitivity to bright light
  • Glare
  • Difficulty driving at night
  • Halos or streaks around bright lights
  • Frequent changes in eyeglass or contact prescription

Other Ectasia

Terrien’s Marginal Degeneration

Terrien’s Marginal Degeneration is a progressive and degenerative thinning of the cornea, usually in the superior (upper) margin of the cornea. It is more commonly seen in males over the age of 40. As the condition progresses, the corneal thinning can extend the entire circumference of the cornea. It can be inflammatory in nature, with neovascularisation (blood vessel growth), lipid deposits and corneal scarring commonly seen.

Pellucid Marginal Degeneration

Pellucid Marginal Degeneration is a progressive, degenerative, noninflammatory corneal condition. It is commonly confused with Keratoconus as it also results in thinning of the cornea, however the area of thinning is typically localised to the inferior (lower) and peripheral cornea. Like Keratoconus, patient’s often present with irregular astigmatism, and vision that can no longer be adequately corrected in glasses or contact lenses.

Keratoconus Diagnosis

Keratoconus is diagnosed with a comprehensive eye exam and a discussion of your history of symptoms. We will carefully analyze the surface and characteristics of your cornea using advanced diagnostic technology. We will also take precise measurements of your cornea to get a baseline idea of its shape, and continue to take annual measurements to detect and track changes.

Treatment Options

Glasses and Contact Lenses

Keratoconus Diagnosis & Treatment in Brisbane, Booval, Wynnum, & AspleyIn the early stages of keratoconus, glasses and contact lenses usually provide the vision correction needed. Special contact lenses are required for keratoconus; the lenses are specifically designed for the large areas of distorted cornea.

Corneal Crosslinking

Corneal crosslinking is a revolutionary procedure that shows promise for delaying or arresting the progression of keratoconus. A combination of riboflavin (vitamin B12) drops and ultraviolet light is used to strengthen the collagen fibers inside the eye. This helps stabilize and strengthen the cornea, slowing down the bulging. Although corneal crosslinking cannot restore any vision that has been lost to keratoconus, it can delay or prevent future vision loss.

Corneal Transplant

In the most severe cases of keratoconus — when glasses or contact lenses can no longer correct vision — corneal transplant may be the best solution. During the transplant, the thinning, distorted corneal tissue is removed and replaced with healthy donor tissue. Surgery is reserved for rare cases, and the results are usually excellent.
