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; and determine a tear film hydration state associated with the optical target based, at least in part, on the received ocular aberrometry output data; determine when a portion of the optical target or when a preset percentage of optical target is detected as below a predetermined minimum aberrometry hydration threshold; and a projection device to project saline onto the optical target when the portion of the optical target or when the preset percentage of optical target is detected as below the predetermined minimum aberrometry hydration threshold.
