A device (100) for measuring aberrations of an eye (3) comprises a first light source (102), a lens (104), and a reflective surface (106). The first light source (102) is adapted to reflect light off the retina (12) of the eye (3) so as to produce a wavefront (112). The wavefront (112) propagates along an optical path (115). The lens (104) receives the light from the wavefront (112). The reflective surface (106) is disposed to reflect the light from the wavefront (112) and the light that is received by the lens (104) is reflected back through the lens (104), so as to produce an image (121) of the wavefront (112). A wavefront sensor (108) is adapted to receive the light from the wavefront (112) that is reflected back through the lens (104) so as to provide a measure of the aberrations of the eye (3). |
