Aims: To compare biometric and topographic measurements obtained with the Aladdin optical biometer and the Pentacam Scheimpflug imaging system in eyes with low and moderate myopia, and to assess agreement between the two devices.Methods: This retrospective study included the right eyes of 58 patients with low or moderate myopia. Myopia was classified according to spherical equivalent. White-to-white corneal diameter (WTW), flat keratometry (K1), steep keratometry (K2), mean keratometry, corneal astigmatism, and anterior chamber depth (ACD) were compared between the devices. Correlations were assessed using Pearson correlation analysis, while agreement was evaluated using the intraclass correlation coefficient and Bland-Altman analysis.Results: The mean age of the patients was 29.62±9.22 years, and the mean spherical equivalent was -2.55±1.35 D. Thirty-four eyes were classified as low myopia and 24 as moderate myopia. Aladdin produced lower WTW, K1, K2, and mean keratometry values than Pentacam, whereas ACD values were higher with Aladdin (p
