Abstract
A system for detecting position data of an element in the front region of an eye. A first system component continuously detects position changes of the vertex of the cornea of the eye. A second system component directs electromagnetic radiation at topographical structures of the cornea to be ascertained or modified. A control unit includes a processor and memory. Alignment of the first system component with respect to the alignment of the second system component is defined, and the second system component is continuously guided to the respective target position thereof, by the control unit based on the position changes detected by the first system component. Light sources, which illuminate the cornea, are symmetrically disposed around the main axis of the system so that a pattern of reflection points is created on the cornea. The processor determines the current position of the vertex as the center of the reflection points.
