(IOL) power by theoretical formulas.10-12 To date, a few

studies investigated the Nidek optical biometer,13-15

but some of them suffer from methodological biases

(in one case14 both eyes of most patients were enrolled

and in another case15 IOL power calculation was not

based on back-calculated constant optimization).

To validate the Nidek AL-Scan, in this prospective

study, we aimed to confirm whether the biometric

measurements have any statistically significant differ-

ence in mean axial length, K values, and ACD.
