An ophthalmological measurement apparatus (10) for determining the axial length (LA) of an eye (4) includes an optical interferometric first measurement system (1) for determining a relative position (A) of the retina (41) of the eye (4), a non-interferometric second measurement system (2) for determining a relative position (B) of the cornea (42) of the eye (4), and processing means (3) for determining the axial length (LA) of the eye (4) on the basis of the relative position (A) of the retina (41) and of the relative position (B) of the cornea (42). The design of the ophthalmological measurement apparatus (10) with an interferometric and a non-interferometric measurement system for a different measuring range in each case on a measurement axis (z) enables the substantially simultaneous determination of the relative positions (A, B) both of the cornea (42) and of the retina (41) without this requiring differently dimensioned optical acquisition systems for determining interference patterns of light reflected at the retina (41) and at the cornea (42).
