Understanding Corneal Topography

Once a topography image is captured, it is now time to evaluate the data collected. The topography will give doctors an image of different colors. The colors reflect steep areas (represented in red and orange) and flat areas (represented in blue). Using the scale on the left, we know how steep or flat certain areas of your eye are. Topography is used to detect eye conditions such as keratoconus, corneal ectasia, post-refractive surgery imaging, and much more. Doctors who fit special contact lenses such as scleral lenses or orthokeratology will rely on topography heavily.
