'Corneal Topography'

A 3-Dimensional Map of Your Eye

OM_Marco _Suppl _March _A01_Fig 04

Corneal topography, also known as photokeratoscopy or videokeratography, allows your Bayfields Optometrist to create a 3-Dimensional map of your eye and forms part of our extensive Bayfields Eye Examination and Contact Lens Fitting.

This ‘map’ is essential in helping to assess the health of your eye, the quality of your vision and is also used by the Optometrist as part of any assessment for suitability for contact lenses.

The process is based on placido reflective image analysis, where multiple light concentric rings are projected onto the cornea. The reflected image is captured on a charge-coupled device (CCD) camera. Computer software then analyses the data and displays the results in various formats for the Optometrist.

Corneal topography is a non-invasive, medical imaging technique for mapping the surface curvature of the cornea (the outer structure of the eye.) Please feel free to discuss corneal topography with a Bayfields Optometrist at your next Bayfields Eye Examination.
