Abstract

The disclosure provides a system that may provide a virtual object at a first virtual distance to an eye of a patient; may provide a first light wave to the eye; may receive a first perturbed light wave, based at least on the first light wave, from the eye; may determine first optical corrections based at least on the first perturbed light; may provide the virtual object at a second virtual distance to the eye; after providing the virtual object at the second virtual distance, may provide a second light wave to the eye; may receive a second perturbed light wave, based at least on the second light wave, from the eye; may determine second optical corrections based at least on the second perturbed light; and may determine a corrective optical solution for the eye based at least on the first optical corrections and the second optical corrections.

provide, via the projector, a virtual object at a first virtual distance to an eye of a patient;
provide a first light wave to the eye of the patient;
receive a first perturbed light wave, based at least on the first light wave, from the eye of the patient;
determine first optical corrections based at least on the first perturbed light;
provide, via the projector, the virtual object at a second virtual distance, different from the first virtual distance, to the eye of the patient;

wherein the instructions further cause the system to:
configure the deformable mirror based at least on the corrective optical solution for the eye of the patient;
provide, via the deformable mirror, the virtual object to the eye of the patient; and
receive input from the patient that indicates if the virtual object is acceptably viewed by the eye of the patient.
