Corneal Topography

Corneal Topography

Corneal topography maps the curvature of the front surface of the eye in fine detail, producing a contour map of the cornea.

Where it is used

• Contact lens fitting — particularly for irregular or hard-to-fit corneas.
• Astigmatism — measured precisely rather than estimated.
• Corneal disease — detecting thinning and distortion such as keratoconus.

The scan is quick, requires no contact with the eye, and informs both everyday prescriptions and surgical planning.
