Corneal topography provides us with a detailed description of various curvature and shape characteristics of the cornea. This information is very helpful for the illustration of corneal astigmatism, detection of corneal pathologies and perfection of contact lens fitting.
Becoming familiar with the basics of topography will allow you to choose the appropriate map for any given patient situation as well as understand the data associated with these maps. This article explains the different topography map types, how to classify corneal astigmatism and corneal shapes associated with various pathologies and how to design contact lenses with the information provided. Even though the image presentations may vary between topographers, this information is universal.
