Claim 0:
1. A system, comprising:
a wavefront aberrometer configured to measure a refraction of an eye;
at least one processor;
a first movable stage, wherein the first movable stage is movable linearly with respect to the eye under control of the at least one processor;
a second movable stage directly mounted on top of the first movable stage, wherein the second movable stage is independently movable linearly with respect to the first movable stage and with respect to the eye in a direction parallel to a linear movement direction of the first movable stage, under control of the at least one processor;
a fixation target for presentation by the system to the eye to cause the eye to accommodate during a process of measuring the refraction of the eye, wherein the fixation target is disposed on the second movable stage; and
an optical system disposed in an optical path between the fixation target and the eye, wherein the optical system is configured for non-telecentric projection of the fixation target upon the eye.
