Common Topography Indices

Updated: Jan 12, 2023




Here are explanations to some common topography indices that you will find across several corneal topography machines. While there is no standardization currently in the industry and different manufacturing companies have their own terminologies to describe often a common indication in the cornea, I have tried to provide a summary and a picuture against the topography indices explaining the same. Hope it helps.





Not definitive but suggestive only.
