Objective: To evaluate the differences and consistency inaxial length, corneal curvature, anterior chamber depth and astigmatism in cataract patientsmeasured by Pentacam AXL and IOLMaster 700. Methods: This was a prospective controlled study. Ninety cataract patients (106 eyes) were enrolled in Xiamen Eye Center of Xiamen University from January to May 2019. Biometry measurements were performed by the same examiner with Pentacam AXL and IOLMaster 700. The axial length (AL), keratometry reading (K1, K2, Km), J0 and J45 vectoral components of astigmatism and anterior chamber depth (ACD) were obtained. The difference between the two instruments was analyzed. Differences and correlations of biometry measurements obtained with the two biometers were analyzed. The agreement between the two biometers was analyzed by Bland-Altman plot. Results: There were no significant differences in AL, Km, J0, J45 or ACD (t=0.035, P=0.972; t=0.348, P=0.728; t=-0.020, P=0.984; t=0.300, P=0.764; t=-0.931, P=0.407) between Pentacam AXL and IOLMaster 700 (23.63±2.06 mm vs. 23.64±2.05 mm, 44.37±1.70 D vs. 44.45±1.71 D, 0.011±0.555 D vs. 0.009±0.598 D, 0.002±0.278 D vs. 0.013±0.289 D, 2.96±0.41 mm vs. 2.91±0.41 mm). All of the biometric parameters showed good correlation (r=1.000, 0.988, 0.911, 0.811, 0.994, P<0.01). The Bland-Altman analysis of AL, J0, J45, ACD with Pentacam AXL and IOLMaster 700 showed a mean difference of 0.01 mm (95%LoA: -0.07-0.05 mm), 0 D (95%LoA: -0.48-0.48 D), -0.01 D (95%LoA: -0.35-0.33 D) and 0.05 mm (95%LoA: 0-0.09 mm) between the 2 devices, respectively, while the mean difference in Km was -0.08 D (95%LoA: -0.59-0.43 D). Conclusions: There is no significant difference in biometric parameters between Pentacam AXL and IOLMaster 700; the 2 devices can be used interchangeably to measure AL, J0, J45 and ACD in cataract patients. However, the Kmvalue is not interchangeable since the devices have a slightly larger variation in measurements.
