摘要：
An ophthalmic apparatus for precisely positioning an optical instrument, such as a wavefront aberrometer, in three dimensions with respect to a patients eye. The ophthalmic apparatus may include an optical instrument directed in a first direction toward a target area to receive light therefrom and a camera directed in a second direction toward the target area to receive light therefrom, the first and second directions being non-parallel. The camera may include imaging optics to form an optical image on a photodetector array using light reflected from the target area. The ophthalmic apparatus may also include a processor configured to correlate a position of the optical image on the photodetector array with the distance between the optical instrument and the target area.
