Abstract: A method of verifying ophthalmic measurements includes obtaining, via an ophthalmic measurement device, a first measurement of at least one ophthalmic parameter over a first measurement area. The first measurement area corresponds to an unassisted visible area of a patient's eye. A second measurement of the at least one ophthalmic parameter over a second measurement area is obtained via the measurement device. The second measurement area corresponds to an assisted visible area of the patient's eye. The first measurement is compared to the second measurement. It is determined if the second measurement diverges from the first measurement. Responsive to a determination that the second measurement diverges from the first measurement, an alert that the second measurement is inaccurate is generated. Responsive to a determination that the second measurement does not diverge from the first measurement, the second measurement is accepted as accurate.

Abstract: A system and method for visualizing an eye using an optical coherence tomography (“OCT”) device includes a controller having a processor and a tangible, non-transitory memory on which instructions are recorded. The OCT device produces an OCT beam defined by an OCT beam axis. The controller is adapted to receive a first dataset captured with the OCT beam axis at a first tilt angle from a first visual axis. The controller is adapted to receive a second dataset captured with the OCT beam axis at a second tilt angle from a second visual axis. A plurality of lens segments is generated based on the first dataset and the second dataset. The controller is adapted to generate a lens profile based in part on the plurality of lens segments.
