Background: The primary objective of this study was to investigate the level of agreement between IOL-Master and OB-820 ocular biometers.
Materials and methods: In this prospective randomized case series, we measured the anterior chamber depth (ACD), the axial length (AL), the corneal radii (R1, R2), the ratio of mean corneal radius and spherical equivalent and the corneal astigmatism (cylinder [Cyl]) before and after cataract extraction surgery.
Results: Significant differences between pre- and postoperative data were observed for ACD for both biometric devices (P<0.01) and Cyl parameter in IOL-Master. Range and 95% limits of agreement (LoA) were clinically significantly different for AL parameter pre- and postoperatively and for R2 and radius and spherical equivalent postoperatively (P<0.001). The rest of the parameters presented sufficient 95% LoA, which imply good agreement.
Conclusion: In clinical practice, the IOL-master and OB-820 should not be used interchangeably due to discrepancy in the important AL parameter. Both biometers may provide consistent results regarding Cyl, ACD and R1.
