Corneal mapping, also known as corneal topography, is diagnostic testing that creates detailed, 3D maps of the surface of the cornea (the clear, front window of the eye).   

The cornea is responsible for most of the eye’s focusing power, and any irregularities in its shape can lead to visual distortions. With a corneal topography scan, our optometrist, Dr. Christine Kniffen, can identify irregularities or distortions in the cornea. She then uses this information to develop a personalized treatment plan tailored to your specific needs, promoting optimal eye health and comfort. 

What is corneal topography used for?    

At Casey Optical Co. in Albuquerque, New Mexico, corneal topography is a valuable tool that we use for a variety of reasons. Corneal topography is helpful in monitoring the progression of corneal diseases over time, such as keratoconus. By detecting changes in the cornea’s shape and curvature, our optometrist can develop customized treatment plans to manage these conditions effectively. In some cases, corneal topography may be used to improve the accuracy of contact lens fitting. By analyzing the surface of the cornea, Dr. Kniffen can determine the ideal size, shape, and type of contact lenses that will provide the best vision correction and the most comfort. 

What to expect when getting a corneal topography scan   

Getting a corneal topography scan is non-invasive and painless. Nothing touches your eyes at any time. You will be seated in front of the corneal topographer and asked to stare at a fixed target inside the machine while pictures of your eyes are taken. The scan only takes a few seconds to complete.
