Abstract:
AIM: To compare the measurement of anterior chamber depth(ACD) inclusive of corneal thickness using intrao-cular lens(IOL) master and ultrasound biomicroscopy (UBM) and evaluate the repeatability of each method.METHODS: Two consecutive measurements of ACD were prospectively performed using IOL master and UBM in 60 eyes in 60 individuals. Mean values were compared using the paired t test. For each individual, ACD measure-ments was performed 5 times to estimate the repeatability of each method by a coefficient of variation(CV).RESULTS: The mean ACD was 2.95±0.25mm with the IOL master and 2.96±0.22mm with the UBM. This diffe-rence was not statistically significant (P=0.631).The coefficient of variation (CV) was 0.56%±0.26% and 0.65%± 0.36% in IOL master and UBM, respectively.CONCLUSION: The mean ACD of IOL master was the same as UBM. The repeatability of IOL master is better than UBM.
