1. An ocular aberrometry system comprising:
a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system; and
a logic device configured to communicate with the wavefront sensor, wherein the logic device is configured to:
receive ocular aberrometry output data comprising at least the wavefront sensor data provided by the wavefront sensor;
determine a synchronized tear film hydration state associated with the optical target based, at least in part, on the received ocular aberrometry output data, wherein the determining the tear film hydration state comprises:
controlling the wavefront sensor and an imaging sensor of the ocular aberrometry system to image the optical target at approximately a same time and/or according to a same rate; and
combining a Purkinje image data-based tear film hydration state determined based, at least in part, on Purkinje image data provided by the imaging system, with a wavefront sensor data-based tear film hydration state determine based, at least in part, on the received wavefront sensor data, by determining the average, median, and/or other statistical combination of the Purkinje image data-based tear film hydration state with the wavefront sensor data-based tear film hydration state; and
generate user feedback corresponding to the determined tear film hydration state based, at least in part, on the received aberrometry output data and/or the determined tear film hydration state.
