Corneal topography 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 normally responsible for some 70% of the eye's eye's focusing power, its topography (shape) is of critical importance in determining the quality of vision.

Computerized corneal topography can be beneficial in the evaluation and diagnosis of certain diseases and injuries as well as fitting difficult contact lens wearers.
*Corneal diseases
*Corneal abrasions
*Corneal deformities

The corneal topography equipment consists of a computer that is connected to a lighted bowl. The bowl reflects a pattern resembling concentric rings off of the cornea's anterior surface while a technician takes an image of the eye using a charge-coupled device camera.

Computer software produces a printout of the corneal shape, using different colors to identify different elevations, much like a topographic map of the earth displays changes in the geagraphy. This testing is painless and brief.
