The Heidelberg Engineering ANTERION Software Comparison Precision and Agreement Study

• ANTERION investigational (Device): Measurements from the investigational device ANTERION with software version 1.5 are to be compared against measurements from the ANTERION with software version 1.2.4 (cleared version)

Primary outcomes

• Central Cornea Thickness [Through study completion, an average of 1 day]: Reproducibility and repeatability of Central Cornea Thickness of ANTERION and the reference device
• Thinnest Point Thickness [Through study completion, an average of 1 day]: Reproducibility and repeatability of Thinnest Point Thickness of ANTERION and the reference device
• Lens Thickness [Through study completion, an average of 1 day]: Reproducibility and repeatability of Lens Thickness of ANTERION and the reference device
• Anterior Chamber Depth [Through study completion, an average of 1 day]: Reproducibility and repeatability of Anterior Chamber Depth of ANTERION and the reference device
• Axial Length [Through study completion, an average of 1 day]: Reproducibility and repeatability of Axial Length of ANTERION and the reference device

Secondary outcomes

• Adverse Events Rate [Through study completion, an average of 1 day]: Adverse events found during the clinical study
