Corneal Topography

Corneal Topography refers to the technology used to measure the shape of the cornea. The cornea is the front area of the eye through which we see. We use a computer to take a picture of your cornea that will allow us to analyze reflections and distortions that can be viewed in the form of a color-coded map.

The information provided in corneal mapping has made it possible for optometrists to better manage various eye conditions and procedures. These maps aid in the fitting of contact lenses and help uncover subtle irregularities to the shape of your cornea that may ultimately affect your prescription and even your ability to have refractive surgery.
