TI  - Comparison of a New Optical Biometer That Combines Scheimpflug Imaging With

AB  - PURPOSE: To evaluate measurement precision and to compare the Pentacam AXL 
      (Oculus Optikgerate, Wetzlar, German), a new optical biometer based on 
      Scheimpflug imaging and partial coherence interferometry (PCI) with that of the 
      OA-2000 biometer (Tomey, Nagoya, Japan), which combines swept-source optical 
      coherence tomography (SS-OCT) and Placido-disk topography. METHODS: Axial length 
      (AL), central corneal thickness (CCT), anterior chamber depth (ACD), aqueous 
      depth (AQD), mean keratometry (Km), astigmatism vectors J0, J45, and corneal 
      diameter (CD) were measured in triplicate by two technical operators. 
      Within-subject standard deviation (Sw), repeatability and reproducibility (2.77 
      Sw), coefficient of variation (CoV), and intraclass correlation coefficient (ICC) 
      were used to assess the Pentacam AXL intra-observer repeatability and 
      inter-observer reproducibility. Paired t-test and Bland-Altman plots were used to 
      determine the agreement between the two biometers. RESULTS: The new optical 
      biometer had high intra-observer repeatability [all parameters evaluated had low 
      CoV (<0.71%) and high ICC (>0.88)]. Inter-observer reproducibility was also 
      excellent, with high ICC (>0.95) and low CoV (<0.52%). The 95% LoA between the 
      new biometer and OA-2000 were insignificant for most of the parameters evaluated, 
      especially for AL. However, the measurement agreement was moderate for CCT. 
      CONCLUSIONS: Intra-observer repeatability and inter-observer reproducibility were 
      excellent for all parameters evaluated using the new optical biometer based on 
      Scheimpflug imaging and PCI. There was a high agreement between the two devices 
      and hence could be clinically interchangeable for the measurement of most ocular 
      parameters.
