Assessment of Measurement Variability Across Automated Biometry Devices

Berkeley Eye Center·observational·Posted Sep 21, 2023·Updated May 13, 2025

In Brief

An observational study evaluating Orbscan II, IOL Master 700, and 7 other interventions for Myopia. Completed, enrolled 204 participants across 1 site.

Detailed Summary

This is a non-interventional prospective, comparative study of white-to-white, corneal thickness, and anterior chamber depth measurements as taken on the Orbscan II compared to the IOL Master 700 (Zeiss), IOL Master 500 (Zeiss), Atlas 9000 (Zeiss), Lenstar 900 (Haag-Streit), Argos (Alcon), iTrace (Tracey), Pentacam (Oculus), and manual calipers.
