There are several methods available for diagnosing Keratoconus. These methods include:
- Eye refraction where an Optometrist uses special equipment to analyze your eyes for vision problems.
- Keratometry which involves your eye doctor focusing a circle of light into your cornea to measure the reflection and check the shape of your cornea.
- Slit-lamp exam involves an eye doctor shining a vertical beam of light on your eye and a microscope to analyze the surface of it. This test assesses the shape of your cornea and can spot other problems too.
- Corneal mapping is a more advanced technique that uses specialized optical coherence tomography and corneal topography to map the shape of your cornea.
- Pachymetry is a test to measure the thickness of the cornea.
