Keratoconus
This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information.

Keratoconus (KC) is a corneal disease which will in many cases ultimately require corneal transplantation to maintain vision. Early detection, which is not possible with current technology, would allow early treatment and prevent severe damage to KC corneas inadvertently operated upon for correction of vision. The investigators' aim is to combine measurements of different properties of the cornea to develop means for early detection of KC.
