AB  - PURPOSE: To evaluate the repeatability of a new swept source optical coherence 
      tomography (SS-OCT)-based biometer to measure anterior segment parameters and to 
      assess the agreement with 3 other imaging devices based on different measurement 
      principles. SETTING: Unit of Eye and Vision, Department of Clinical Neuroscience, 
      Karolinska Institute, Stockholm, Sweden. DESIGN: Prospective, comparative case 
      series. METHODS: 3 consecutive measurements were obtained in unoperated eyes with 
      the Eyestar900 (SS-OCT), Lenstar 900, MS-39, and Sirius. The following anterior 
      segment parameters were evaluated: central corneal thickness (CCT), corneal 
      diameter (CD), aqueous depth (AQD), and corneal power metrics. The repeatability 
      limit (Rlim), coefficient of variation (CoV), and a repeated measures 
      Bland-Altman analysis were performed. RESULTS: 74 eyes of 74 participants were 
      measured. The Rlims for CCT, CD, and AQD were lower than 10 mum, 0.3 mm, and 0.10 
      mm for all devices, respectively. The corresponding CoVs for these parameters 
      never exceeded 1.2%. The Rlim for the corneal power metrics never exceeded 0.60 
      diopter (D) for any of the instruments. Lenstar showed the best agreement with 
      the MS-39 to measure CCT, CD, and AQD (limit of agreement interval, LoA: 15.54 
      mum, 0.55 mm, and 0.16 mm, respectively). The mean difference for keratometry 
      parameters was lower than 0.3 D for all device comparisons, and the LoA interval 
      ranged between 0.52 D and 1.21 D. CONCLUSIONS: The repeatability for measuring 
      anterior segment parameters was good, and the agreement among all the instruments 
      was good for CD and AQD measurements. However, for CCT and keratometer 
      parameters, the instruments cannot be used interchangeably due to large LoA 
      interval.
