[Keratoconus progression assessment].

Keratectasias including keratoconus are pathological curvature anomalies of the human cornea, which can progress and lead to permanent visual impairment. Corneal crosslinking can be used to stabilize the disease. Criteria for performing crosslinking have been defined by legislation in Germany, including an increase of the maximum anterior surface curvature Kmax by ≥ 1 diopter within 12 months. Unfortunately, there is still a lack of generally applicable standards for assessment of keratectasia progression. This overview presents the possibilities of topographic, tomographic and biomechanical assessment of progression in keratoconus.
