6.4 Measured variables
In-vivo repeatabilities reported in this chapter are based on N=46 eyes (one eye per
subject). 32 phakic (healthy and cataract) and 14 pseudophakic eyes were included.
In-vivo repeatability is calculated as the standard deviation of pairwise differences of
three repeated measurements per eye for all eyes. Aphakic and oil-filled eyes can
be measured with the device. The reported in vivo repeatability does not include
these eye types.
