An apparatus for determining aberrations of an eye includes a patient head rest allowing for positioning adjustment. The patient head rest is operable with an optical table having a base. The base includes a probe beam generating apparatus, probe beam directing optics which itself comprises a beam splitter; a mirror; and a lens. The probe beam directing optics is capable of directing a probe beam toward an eye of a patient positioned on the patient head rest. Video image components are provided and comprise a light source, a mirror; and a video camera. The video image components are capable of generating an image of an eye of a patient positioned on the patient head rest. Eye fixation components generate a target that the eye of a patient positioned on the patient head rest can view. The eye fixation components comprise a fixation target, a light source, a lens, and a mirror. Wavefront directing and analyzing components measure a wavefront emanating from the eye of a patient positioned on the patient head rest and determine aberrations of the eye that range from at least about + or - 1 diopters to at least about + or - 6 diopters. The wavefront directing and analyzing components include a lens; a mirror, a microlens array, a camera, and a data processor.

1. A method for determining higher order aberrations of an eye requiring a correction of greater than -6 diopters, the method comprising:directing an optical beam onto a retina of an eye; reflecting the optical beam from the retina of the eye; determining characteristics of a wavefront in the reflected optical beam; and generating data based on the characteristics of the wavefront, which data quantifies at least one higher order aberration of the eye.
