Abstract: In certain embodiments, an ophthalmic surgical system for adjusting a dimension of an eye includes a camera and a computer. The camera generates a surgical image of the eye in contact with a patient interface, which distorts the cornea. The surgical image includes the pupil with a real pupil diameter. The computer accesses a diagnostic image of the eye with the cornea having a natural curvature. The natural curvature affects the real pupil diameter to yield a diagnostic pupil diameter of the diagnostic image that is different from the real pupil diameter of the surgical image. The computer adjusts the real pupil diameter of the surgical image using an eye model to yield a refracted pupil diameter that takes into account the curvature of the cornea and uses the refracted pupil diameter to compensate for the difference between the diagnostic and real pupil diameters.

Abstract: In certain embodiments, a system for calibrating the focal point of a laser beam comprises a laser, focusing optics, detector optics, a two-photon absorption (TPA) detector, and a computer. The laser generates the laser beam. The focusing optics direct the focal point of the laser beam along a z-axis towards a zero-surface corresponding to a zero-plane, and receives a portion of the laser beam reflected by the zero-surface. The detector optics receive the reflected portion from the focusing optics, and directs the reflected portion towards a TPA detector. The TPA detector senses the peak intensity of the reflected portion, which indicates a proximity of the focal point to the zero-surface, and generates a signal representing the peak intensity of the reflected portion. The computer determines whether the focal point of the laser beam is calibrated in response to the signal representing the peak intensity.

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.
