We are also proud to offer our patients corneal topography services. Also known as photokeratoscopy or videokeratography, corneal topography is a non-invasive and painless imaging technique that enables us to create a 3D map of the surface curvature of the cornea – the outer structure of the eye – within seconds.
Your cornea is responsible for 70% of your eyes’ refractive power, so these maps allow us to identify the first symptoms of vision-threatening eye conditions, fit contact lenses and assess the suitability of your eyes for laser eye surgery.
So how does the procedure work?
Your optometrist will sit you facing a bowl featuring illuminated concentric rings. This pattern is focused on the surface of your cornea and reflected back into a digital camera, revealing a topological map of your cornea. This is an incredibly useful tool for assessing your eye health and making sure your contact lenses are the perfect fit.
