Abstract
An opthalmologic device and an opthalmologic measuring method in accordance with an embodiment of the present application in which, cross-sectional images of cross-sectional portions illuminated from different instrument positions by a light projector are captured in Scheimpflug configuration. Furthermore, corresponding top view images are also captured from the different instrument positions. At least one reference section and at least one comparative section are extracted from an initial instrument position or from an advanced instrument position, respectively. The displacement between the reference section and the comparative section is determined and the cross-sectional images are positioned relative to one another, based on the displacement. A coherent examination of the entire eye is made possible in which the relative movements of the eye with respect to the device, particularly rotational movements, are taken into consideration.
