Comparison Between Two Ss-OCT Biometry

Status Completed

Clinical Trial Summary

Since recently a second swept-source optical coherence tomography (ss-OCT) optical biometry device was launched (Anterion, Heidelberg Engineering). Aim of this study is a retrospective data collection of patients who were measured with both ss-OCT optical biometry devices and to assess the limits of agreement of the two devices.

Retrospective comparison of two ss-OCT biometry devices concerning comparability of measurements of axial eye length, anterior chamber depth, lens thickness and keratometry.

Clinical Trial Description

This a retrospective study including data acquired from patients that attended pre-surgical examination as it is the standard in the investigator's hospital.

The IOL Master 700 (Carl Zeiss Meditec AG, Jena) and the Heidelberg Anterion (Heidelberg Engineering, Germany) are biometry devices that use swept-source optical coherence tomography technology in combination with a multidot-keratometer, that obtain two-dimensional images of ocular structures.

The difference between the two devices resides in the wavelength of the infrared laser: 1200-1400nm for the Anterion and 1050nm for the IOL Master 700.

The SS-OCT devices provide a scan depth of 44mm and a resolution in tissue of 22 μm for the IOL Master 700 and of 14x16.5 mm and 30 μm for the Heidelberg Anterion. ;
