Abstract:
Purpose:To compare the ocular biometry and postoperative refractive outcomes using two devices; the swept-source opticalcoherence tomography biometer (Argos) versus the partial coherence interferometer (IOL Master®500, Carl Zeiss Meditec AG,Jena, Germany).
Methods:The axial length (AL), anterior chamber depth (ACD) and keratometry (K) in 221 cataract eyes were measured withArgos and IOL Master®500. One month after surgery, refraction of the respective eyes was conducted and the mean absoluteerror (MAE) calculated for analysis of the refractive outcomes.
Results:Measurement was not possible in 13 eyes with the IOL Master®500 but was possible with Argos. Measurement was notpossible in one eye with either biometer. Agreement in measured ocular biometry between the two devices by intraclass correlationcoefficient (ICC) and Bland-Altman plot (ICC AXL = 0.999, ACD = 0.975, K = 0.978) was excellent. The AL and ACD measuredwith Argos were significantly longer than measured with IOL Master®500 (p= 0.005, p= 0.000). The MAE showed no significantdifference between the Argos and IOL Master®500 (p= 0.087).
Conclusions:The measurement of ocular biometry was better in Argos than in IOL Master®500. The accuracy of the intraocularlens power calculations of Argos was clinically acceptable and compatible with a conventional device.
