Corneal thickness maps of a cornea from the same subject obtained sequentially on the same day by (A) Oculyzer II Scheimpflug camera, (B) OptoVue AS-OCT, and (C) Artemis II HF-UBM. We observe “thinner measurements” of corneal thickness (eg, centrally) by the AS-OCT versus the Scheimpflug and the HF-UBM (−15 μm).
Abbreviations: AS-OCT, anterior-segment optical coherence tomography; CCT, central corneal thickness; HF-UBM, high-frequency ultrasound biomicroscopy.
