Claim 0:
1. A method for determining an ocular aberration of at least one eye of a user, the method comprising the following steps:
a) measuring at least one optical wavefront comprised by at least one light beam, wherein an ocular aberration of the at least one eye of the user is determined from the at least one optical wavefront; and
b) generating multiple diffraction orders in the at least one light beam in two meridians in a manner that the multiple diffraction orders are spatially separated in the at least one eye of the user and on the wavefront sensing unit,
wherein, the multiple diffraction orders include at least a zeroth diffraction order and at least two first diffraction orders in each meridian, wherein at least nine light spots are generated across the wavefront sensing unit in the two meridians.
