Corneal topography

Corneal topography is a non-invasive medical imaging technique used to map the surface of the cornea, the clear dome-shaped surface at the front of the eye. It measures the curvature and shape of the cornea, providing a detailed visual representation of its topography.

Corneal topography is used to:

• Diagnose and monitor corneal diseases, such as keratoconus and Fuchs’ dystrophy
• Plan and monitor refractive surgeries, like LASIK and PRK
• Fit contact lenses, especially in cases of irregularly shaped corneas
• Detect corneal injuries and traumas
• Monitor corneal transplants

The test involves:

• Sitting in front of a corneal topographer machine
• Looking into a bowl-shaped device
• A low-intensity light is projected onto the cornea
• The machine measures the reflection and creates a map of the corneal surface

Corneal topography is usually performed by an eye care professional (optometrist or ophthalmologist) and takes only a few minutes to complete.

Note: While corneal topography is not directly related to dentistry, it is an important diagnostic tool for eye health, and dentists often work closely with eye care professionals to ensure overall patient health.
