An apparatus for determining an orientation of anatomical cornea structures includes: a lighting device, configured to direct a first luminous radiation, polarized with an orientable polarization direction, towards a cornea, when the cornea is in an observation seat； a control device, configured to modify an orientation of the polarization direction； an image acquisition device, arranged so as to receive a second luminous radiation, transmitted through the cornea arranged in the observation seat and illuminated by the first luminous radiation； and an acquisition polarizing filter, arranged so as to intercept the second luminous radiation directed towards the image acquisition device.
