Table 1

Average values of axial length, anterior chamber depth, and central corneal thickness. Mean/SD refers to the mean value/standard deviation of 10 shots within each measurement. Within a sequence of 5 repeated measurements, meanMEAN is the average of the MEAN, sdMEAN is the standard deviation of the MEAN, and meanSD is the average of the SD values. AL refers to axial length, ACD to anterior chamber depth, and CT to central corneal thickness.
