Case series further illustrates the advantage of the biomechanical assessment in cases without topographic or tomographic abnormalities. In this case series 12 cases are presented without any tomographic abnormality in one eye but clear ectasia in the other eye. Biomechanical properties were already altered in the tomographic normal eyes.
