Device and method for determining geometric measurement values of an eye

A device for determining geometric measurement values of an eye, in particular a human eye, comprising:

• a light projector for projection of a beam of rays through a section of the eye, and
• imaging means for capturing a first image of at least a partial region of the section illuminated by the light projector, at a first observation angle, from a first position outside the beam of rays, and for capturing a second image of the partial region at a second observation angle, from a second position outside the beam of rays,
• wherein it further comprises:
• image processing means to identify eye structures from the first captured image, to identify eye structures from the second captured image, to measure a first distance between the eye structures identified from the first image and to measure a second distance between the eye structures identified from the second image, and
• processing means to calculate at least one of said geometric measurement values from the measured first distance and the measured second distance.
