Abstract: A multifocal capable ophthalmic aberrometer has an afocal relay defining an optical axis, an object plane, and an image plane. The image plane is conjugated to the object plane. A probe beam is projected along the optical axis and is propagated toward the object plane. Reflection of the probe beam from a subject eye located at the object plane generates a wavefront emerging from the object plane. A Hartmann-Shack sensor positioned at the image plane and produces an image of Hartmann-Shack spots of the wavefront. A control electronics acquires the images of the Hartmann-Shack spots in a single measurement. A processing electronics calculates an optical power map of the subject eye with respect to a center of the wavefront and averages the optical power map over the images.

Abstract: The present invention contemplates an ophthalmic adaptive-optics instrument to obtain patient-verified prescription of low- and high-order aberrations. The present invention further contemplates a new and improved method and apparatus of customized corneal ablation using a patient-verified prescription of low- and high-order aberrations. The patient-verified prescription of high-order aberrations characterizes the aberration correction needed for optimal visual acuity and enables customized corneal ablation to achieve optimal visual acuity of each individual patient.
