Abstract

Purpose: To assess the agreement on biometric data obtained using the Verion image-guided surgery system and the swept-source-OCT biometer IOL Master 700. Materials and Methods: All patients underwent biometry using the SS-OCT and the Image-Guide System. The comparison between instruments was assessed using the Intraclass correlation coefficient (ICC). Level of Agreement (LoA) employing the Bland-Altman analysis. Results: The image-based system produced significantly higher keratometry values, evidencing a low LoA between the SS-OCT and the image-based system, ranging from −1.30 D to 0.65 D (1.95 D), −1.04 D to 0.72 D (1.76 D), and −1.31 D to 0.65 D (1.96 D), respectively. The LoA for the Cylinder ranged from −0.46 D to 0.74 D (1.2 D) and from 0.82 to 0.94 mm for WTW. Conclusions: In our study, the SS-OCT biometer and the Image-based System evidenced statistically significant differences in measuring the main biometric parameters except for the WTW.
