Question: What is corneal topography, and why would someone need this test during an eye examination?
General Eye Health
Answer: Corneal topography is a scan that maps the shape and curvature of the cornea, which is the clear front surface of the eye. It is useful for detecting irregular astigmatism, keratoconus, dry eye-related surface issues, and for fitting contact lenses more accurately. It can also help explain why some people still feel blur even with glasses.
