Acquisition times were registered for different conditions: time required for one complete measurement with IOLMaster 700 with central topography, time required for one complete measurement with standard IOLMaster 700 (without central topography), time required for one complete measurement with standard IOLMaster 700 plus time required for one complete measurement with Cassini, and time required for one complete measurement with standard IOLMaster 700 plus time required for one complete measurement with Pentacam HR. In addition, the agreement between keratometry (K), total keratometry (TK) and equivalent K reading (EKR) parameters using the three devices was performed.Results: The post hoc Tukey’s test revealed that there were statistically significant differences for all pairwise comparisons (p 0.05).Conclusion: We consider that this is an efficient procedure that improves clinical flow. We also conclude that K readings obtained with the three devices cannot be used interchangeably since there are clinically relevant differences that may affect cataract surgery outcomes.Keywords: IOLMaster 700, optical biometer, cataract, Scheimpflug imaging, color LED
