[0040] 1. A computer-implemented method for detecting the corneal apex, wherein a frontal image of the head and a lateral image of the head are provided, these images being calibrated to each other, wherein, from the frontal image and the The profile image determines the spatial position of the corneal apex.
[0041] 2. The computer-implemented method according to item 1, characterized in that triangulation is used in determining the geometric position.
[0042] 3. The computer-implemented method according to item 1 or 2, characterized in that the position of the corneal apex is corrected for calculation.
[0043] 4. The computer-implemented method according to one of the preceding items, characterized in that the position of the corneal apex in space is determined in a first approximation as an intersection point q, which is the side camera that captures the side image Intersection of a first line of sight ( 52 ) tangential to the cornea ( 50 ) of ( 16 b ) and a second line ...
