1. A device for measuring biometric variables of eyes, comprising:
a multi-point keratometer and an OCT arrangement;
the multipoint keratometer comprising an illumination structure;
the illumination structure comprising multiple individual illumination points that are spaced apart from one another;
wherein the illumination points are arranged in three rings concentrically around an instrument axis; and
wherein the three rings include a first ring, a second ring and a third ring and the illumination points on the first ring and the third ring are rotated in relation to the illumination points on the second ring such that each of the illumination points on the first ring is on a common radial with one of the illumination points on the third ring and each of the illumination points on the second ring is not on the common radial.
