Results with the Lenstar LS 900® are also consistent with previous toric IOL studies in the literature, some of which also used automated devices for keratometry readings. Ahmed et al.

[55] These devices performed accurate measurements, but were mainly replaced by the keratometry measurements that are integrated into the optical biometry devices. The two main light-scatter ...

If the pupils have a diameter as small as 2 mm, readings may still be acquired using the small pupil mode. Up to 10 measurements of Refractometry and Keratometry may be stored for each eye.
