Corneal Topography in Fez: The Key Test for Keratoconus

Corneal topography is the reference examination for screening and monitoring keratoconus. Quick, painless and contactless, it “maps” the surface of your cornea and reveals deformations that are sometimes otherwise invisible.

What is corneal topography?

It is a kind of “relief map” of the cornea. The device projects luminous rings onto the eye and measures their reflection to reconstruct, point by point, the curvature of the cornea. The result is a color map: you can immediately see whether the cornea is regular or deforming.

Why is it essential for keratoconus?

• Detect early : it detects early keratoconus, even before vision clearly deteriorates.
• Confirm the diagnosis : when faced with distorted vision or frequently changed glasses, it gives a clear answer.
• Monitor progression : repeated over time, it allows comparison and detection of any progression.
• Fit contact lenses : it guides the choice and adjustment of rigid or scleral lenses.

How does the examination work?

You rest your chin on a support, fix your gaze on a target, and the device takes the measurement in a few seconds — without touching the eye and without pain. No special preparation is needed. The doctor then explains the resulting map to you.

Key takeaway

Corneal topography is the key tool to detect keratoconus early and monitor it. If your vision is becoming distorted or you change glasses often, it is the examination that brings clarity.
