Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is responsible for about 70% of the eye's refractive power, this mapping is of critical importance in determining the quality of vision.
The three-dimensional map is a valuable aid that assists our optometrist in the diagnosis and treatment of a number of conditions. The mapping also plays an important role when determining if someone is a good candidate for refractive surgery such as LASIK, or when assessing the fit of contact lenses on the cornea. The results from the three-dimensional map is achieved in seconds and is completely painless.
