Corneal cross-linking is a treatment used to strengthen the cornea and help slow or stop keratoconus progression. Learn how it works, who may need it, and why early monitoring is important.

Corneal topography and Pentacam tomography provide detailed information about corneal shape, elevation, and thickness. This clinician-friendly guide explains how to interpret each map, recognize patterns of keratoconus and other thinning disorders, evaluate progression, and avoid common diagnostic mistakes.

Keratoconus is an eye condition that affects the cornea, the clear front window of the eye. In a healthy eye, the cornea has a smooth, dome-like shape. With keratoconus, the cornea gradually becomes thinner and steeper, causing it to bulge forward into a cone-like shape. This change can distort how light enters the eye, leading to blurry, shadowed, or irregular vision. Keratoconus often starts in the teenage years or early adulthood, but it can be diagnosed at different ages.
