Keratoconus Assessment
1
Keratoconus can cause increasing blur, distortion and frequent prescription changes — but early assessment can help guide the right management.
Our Keratoconus Assessment & Management service evaluates the shape, curvature and thickness of the cornea, together with your vision and prescription, to identify changes that may be associated with keratoconus and determine the most appropriate next steps.
What We Assess
| Corneal Shape & Curvature | Uses corneal mapping to assess the shape and curvature of the cornea for irregularities associated with keratoconus. |
| Corneal Thickness | Evaluates corneal thickness where clinically appropriate to support assessment and monitoring. |
| Vision & Refraction | Checks visual acuity, astigmatism and prescription changes that may be related to irregular corneal shape. |
| Progression & Eye Health | Compares relevant findings over time to help identify changes and determine whether further specialist assessment may be needed. |
Who Should Consider This Assessment?
- Frequent or unexplained changes in spectacle prescription
- Patients with high, increasing or irregular astigmatism
- Blurred, distorted or ghosted vision that is not fully corrected with glasses
- Increasing sensitivity to glare, halos or difficulty seeing at night
- People with a family history of keratoconus
- Patients already diagnosed with keratoconus who require ongoing monitoring
More Than Just Astigmatism
Keratoconus occurs when the cornea becomes progressively thinner and develops a more irregular or cone-like shape. This can cause increasing astigmatism, visual distortion and reduced quality of vision that may not be fully corrected with ordinary spectacles.
Detailed corneal assessment helps distinguish keratoconus from more routine refractive changes and provides useful information for ongoing monitoring and management.
Management Depends on the Stage
Management is tailored to the severity and stability of the condition. Depending on your findings and visual needs, our optometrists may discuss spectacle correction, soft contact lenses, hard / RGP lenses or other specialised contact lens options.
If there are signs that keratoconus may be progressing, referral to an ophthalmologist may be recommended for further assessment and discussion of treatments such as corneal cross-linking where appropriate.
Early assessment and regular monitoring are especially important because keratoconus can change over time, particularly in younger patients.
