Clinical Trial ES 900 - 2019

Clinical Trial - ES 900 - 2019

The primary objective of this clinical trial is to assess the clinical performance of the investigational device. To that end, the Limits of Agreement with respect to comparator devices are analyzed. The Limits of Agreement allow estimating the expected measurement deviation per measurand, which is compared to the "maximum acceptable measurement error", as defined by the Risk Analysis of the investigational device, to assess the risk involved in measurements of the investigational device. Furthermore, the in-vivo repeatability will be quantified for each measurand, as well as the confidence intervals for mean deviation with respect to the current gold standard device.

As a secondary objective of the study, raw measurement data will be collected to allow for improvement of existing algorithms, development of additional measurands and for retrospective analysis.

The EYESTAR900 (the investigational device) is a new device by HAAG-STREIT AG, for measurement of optical biometry and advanced corneal topography by swept-source optical coherence tomography (OCT).
