The planned clinical investigation will be conducted to acquire raw data for the development of the algorithm. The data acquisition is intended to obtain first impressions of the potential performance of the changed hardware and software components and to confirm the safety profile assessed by risk analysis.

Affected measurements - OCT measurements
It will be investigated, whether the measurements with the study prototype device are affected by the base movement. \- OCT measurements This outcome will be investigated by comparing the raw data of the study prototype device with the data measured with the marketed IOLMaster 700 and Pentacam / MS-39 devices. Non-optimal positioning and movement could possibly cause blurred images that would prevent a detailed analysis
Time frame: day 1
Affected measurements - Keratometry and Topography measurements
It will be investigated, whether the measurements with the study prototype device are affected by the base movement. \- Keratometry and Topography measurements This outcome will be investigated by comparing the raw data of the study prototype device with the data measured with the marketed IOLMaster 700 and Pentacam / MS-39 devices. Non-optimal positioning and movement could possibly cause blurred images that would prevent a detailed analysis
Time frame: day 1
Affected measurements - - WTW measurements
It will be investigated, whether the measurements with the study prototype device are affected by the base movement. \- WTW measurements This outcome will be investigated by comparing the raw data of the study prototype device with the data measured with the marketed IOLMaster 700 and Pentacam / MS-39 devices.
