Objective To assess the agreement of ACD measurements among Galilei II, Pentacam and IOLMaster in myopic eyes. Methods Forty eyes of forty healthy myopia volunteers, whose spherical equivalent were -1.00~-8.00 D, with an average of -4.40±1.80 D, were enrolled in this prospective study. ACD were randomly measured by Galilei II, Pentacam and IOLMaster. The differences between ACD measurements by the 3 devices were analyzed by Bonferroni-corrected repeated-measures analysis of variance. Pearson correlation and Bland-Altman analysis were used to assess the correlation and agreement among the 3 measurements. Results The ACD (mean±standard deviation) with Galilei II, Pentacam and IOLMaster were 3.81±0.20 mm, 3.72±0.20 mm and 3.71±0.20 mm, respectively. Good correlation were found between any two of 3 devices (r=0.984, 0.970, 0.968, P<0.01). The difference between Galilei II and Pentacam was 0.10±0.04 mm and statistically significant (P<0.01). The difference between Galilei II and IOLMaster was 0.10±0.05 mm and statistically significant (P<0.01). The difference between Pentacam and IOLMaster was 0.00±0.05 mm without statistically significant difference (P>0.05). The 95% limits of agreement between Galilei II and Pentacam, Galilei II and IOLMaster, Pentacam and IOLMaster were 0.026~0.167 mm, 0.004~0.195 mm and -0.096~0.102 mm, respectively. Conclusion In myopic eyes, Pentacam measured similar ACD values with IOLMaster. Galilei II measured slightly deeper ACD than either Pentacam or IOLMaster, the differences were within clinically acceptable level. Therefore, they can be regarded clinically interchangeable in measuring myopic eyes.
