Corneal mapping, also known as corneal topography, is a non-invasive diagnostic procedure used to create a detailed map of the curvature and shape of the cornea (the transparent front surface of the eye).

The cornea is responsible for most of the eye’s focusing power. Any irregularities in the shape of the cornea can lead to visual distortions. With a corneal topography scan, our eye doctor can identify irregularities or distortions in the cornea.

What is corneal topography used for?

Corneal topography is useful for planning eye surgery, monitoring and treating corneal conditions, and fitting contact lenses. Your eye doctor may recommend a corneal topography scan for several different reasons:

• Contact lens fitting 
• Evaluation of astigmatism
• Evaluation of dry eye
• Pre-operative assessment for LASIK surgery

What to expect when getting a corneal topography scan

During the corneal mapping procedure, a special device called a corneal topographer projects a series of rings onto the cornea and measures their reflections using a computerized analysis.

This data is then used to create a 3D map of the corneal surface. Corneal mapping is a safe, quick, and painless procedure that provides valuable information about the shape and condition of the cornea, which helps us diagnose various eye conditions such as corneal irregularities, keratoconus, astigmatism, and other visual distortions.
