For decades, eye doctors have used and in some offices still use a device called a keratometer to measure corneal curvature in two places on the eye.
Our Corneal Topography measures curvature at up to 22,000 locations, much more fully detecting eye shape for contact lens fitting, detection of "irregular astigmatism," detection of eye disease, and detection of refractive surgery complications.
We routinely perform corneal topography on contact lens patients to help you get the best fit possible.
