PURPOSE. Ophthalmic parameters can be measured with different techniques and devices. Our aim was to measure anterior segment parameters using 2 optical devices and to compare the data to ultrasonic technique. %26lt;br%26gt;METHODS. Axial length (AL) was measured with IOLMaster; anterior chamber depth (ACD) was determined using IOLMaster, Visante (R) optical coherence tomography (OCT), and Pentacam (R) HR; and central corneal thickness (CCT) were measured with Pentacam (R) HR and with ultrasound. %26lt;br%26gt;RESULTS. In 45 eyes of 45 patients (age 62.73 +/- 15.31), the AL was 23.35 +/- 1.49 mm. The CCT was 541.7 +/- 39.9 mu m with Visante OCT, 549.7 +/- 39.2 mu m with Pentacam (R) HR, and 534.3 +/- 41.3 mu m with ultrasonic device. The ACD was 3.0 +/- 0.42 mm with IOLMaster, 3.26 +/- 0.95 mm with Visante OCT, and 3.06 +/- 0.41 mm with Pentacam (R) HR. In case of CCT measurements, data obtained with Pentacam HR correlated with the results of ultrasonic measurements (r=0.89; p%26lt;0.001) and Visante OCT measurements (r=0.88; p%26lt;0.001). Regarding ACD results, a significant correlation was observed between Pentacam HR and IOLMaster (r=0.95; p%26lt;0.0001) but they did not significantly correlate to Visante OCT data (r=0.23; p=0.12). Correlation was significant between AL and ACD measured with IOLMaster (r=0.67; p%26lt;0.001). %26lt;br%26gt;CONCLUSIONS. The CCT and ACD data show strong correlation between different devices.
