What is corneal topography and how does it help diagnose astigmatism?

ANSWER

Corneal topography is advanced technology that provides the most detailed information about your cornea’s shape. The doctor will tell you to look at something specific. Meanwhile, the device collects thousands of tiny measurements. A computer then builds a color map of your cornea from the data. Your doctor will refer to it if you need surgery for astigmatism or cataracts, or to fit your contacts. It can also help diagnose keratoconus, a disease that causes large amounts of astigmatism.
