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.
