PURPOSE: The objective of this study was to assess the concordance between the values obtained in measuring central corneal thickness using the OrbscanIIz® and the contact ultrasonic pachymeter available in our public ophthalmology service. METHODS: Measurements were taken from 88 eyes of 44 patients using the two instruments. The data obtained were statistically analyzed using version 22 of the IBM SPSS® program. RESULTS: The mean of central corneal thickness measurements obtained from OrbscanIIz® was significantly higher than that obtained from ultrasound pachymetry. However, the mean of differences between both instruments was only 7.22 μ, which could be considered a clinically insignificant result when considering the good concordance obtained between both systems. CONCLUSION: OrbscanIIz® and ultrasound pachymetry can be interchangeable in the usual public clinical practice when measuring central corneal thickness. This is the first research found in the literature that uses a concordance study to compare the data resulting from central corneal thickness measurements obtained by an OrbscanIIz® and an OcuScan® pachymeter in our environment.
