“…Hsieh et al investigated the agreement between corneal power and thickness measurements obtained from the Pentacam and Galilei systems in post-LASIK corneas [ 16 ]. They found consistency between Galilei-derived corneal power values and those obtained by Pentacam, with no significant differences in CCT.…”

Objective The objective of this study was to compare K1, K2, Kmax, and pachymetry values from Pentacam and Galilei scans of corneal topography in order to assess their correlation and interchangeability in clinical practice. Methodology A total of 34 patients (68 eyes) were enrolled in the study. Corneal topography was performed using Pentacam and Galilei devices on the same day. K1, K2, Kmax, and pachymetry readings were obtained from the scans and analyzed using paired t-tests and Bland-Altman plots. Results There were minimal differences in clinical settings between Pentacam and Galilei for K1, K2, Kmax (>0.75 D), and pachymetry values (>15 um). However, there was a statistically significant difference found between Kmax and pachymetry, making their interchangeability questionable. Conclusion Pentacam and Galilei demonstrate a good correlation between corneal keratometric values (K1, K2, and Kmax) and pachymetry values in clinical settings, and they should be used interchangeably with caution.

“…[ 16 ] Otherwise, Galilei ® and Pentacam ® were not interchangeable for post-LASIK evaluation, as data obtained were not identical when assessing these patients. [ 17 ] In corneal edema, ultrasound pachymetry, Pentacam® and AS-OCT were able to reach a high level of agreement in higher degrees of disease, but significant differences were found when patients with lower degrees of corneal edema where measured.

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.
