New article: Repeatability of the Pentacam HR in Various Grades of Keratoconus

To understand the relative importance of tomographic indices of the Pentacam in the follow-up of keratoconus, we looked at their repeatability for varying stages of the disease, as well as for normal eyes. Maximum anterior curvature, often used in keratoconus follow-up, has a variability larger than the minimum threshold for progression (1D), confirming that this an unsuitable parameter for this purpose. Meanwhile, the zonal parameters performed well, suggesting that these parameters deserve further consideration.
