Abstract

Purpose: To compare measurements obtained by Galilei™, Pentacam® (Oculus, Wetzlar, Germany) and Lenstar® (Haag-Streit, Koeniz, Switzerland) and analyze the agreements of the measurements.

Methods: Central corneal thickness(CCT) and Anterior chamber depth(ACD) were measured by Galilei, Pentacam, and Lenstar in 47 eyes of 25 healthy subjects. The measurements were compared among the 3 devices.

Results: The average measurements of CCT by Galilei, Pentacam, Lenstar were 552.6 ± 29.41 μm, 543.9 ± 30.50 μm, 537.5 ± 30.26 μm, respectively. The measurements were significantly correlated with each other (r>0.9, p<0.001), but were statistically significantly different (p<0.001). The average measurements of ACD by Galilei, Pentacam, Lenstar were 3.23 ± 0.360 mm, 3.22 ± 0.403 mm, 3.19 ± 0.367 mm, respectively. The measurements were significantly correlated with each other (r>0.9, p<0.001), but were statistically significantly different (p=0.034). The 95% limits of agreements(LoA) of CCT between Galilei and Pentacam, Pentacam and Lenstar, Lenstar and Galilei were 31.95 μm, 44.76 μm, 46.57 μm, and 95% LoA of ACD were 0.46 mm, 0.32 mm, 0.28 mm, respectively.

Conclusions: CCT and ACD measured by the 3 devices were highly correlated with each other, but the measurements were statistically different. Therefore, those measurements were not interchangeable and these differences should be considered in clinical use.
