Background And Objective:
Anterior chamber depth (ACD) is an important anterior segment parameter. This study compared ACD measurements conducted with two optical devices in phakic, emmetropic eyes.
Patients And Methods:
Eighty-three phakic eyes of 44 patients with a mean axial length of 23.06 ± 0.94 mm were enrolled in the study. ACD was measured three times with the Scheimpflug-based Pentacam HR (Oculus, Wetzlar, Germany), then three times with IOLMaster (Carl Zeiss Meditec, Dublin, CA), and data were statistically analyzed.
Results:
The measurements resulted in a mean ACD of 3.01 ± 0.34 mm with Pentacam HR and 2.95 ± 0.32 mm with IOLMaster. Distribution of data was normal, and no significant difference in ACD values was detected (P = .29) between the two devices. Correlation between ACD measurements was highly significant (r = 0.85; P < .0001).
Conclusion:
In phakic eyes, ACD measured with Pentacam HR and with IOLMaster showed similar values, and high correlation was observed between these two devices.
