We thank Faschinger and Mossböck for their interest in our article.1 The objective of the study was to assess the safety, tolerability, and reproducibility of IOP patterns of the new CLS. These investigations were essential before proceeding to clinical validation of CLS readings. The results of those studies are forthcoming. In the meantime, we agree that evaluation of the clinical validity of any new tonometer or IOP monitoring device is fundamental. Six decades after the introduction of Goldmann applanation tonometry, we are guardedly optimistic that the glaucoma community will gain access to devices for temporary and permanent continuous 24-hour IOP monitoring.2 The wealth of data that these provide (whether in millivolts or in millimeters of mercury) will challenge the scientific community to come up with new analyses and interpretation algorithms to personalize and potentially improve the management of patients with glaucoma.
