Claim 11:
12. A method comprising:
receiving ocular aberrometry output data from an ocular aberrometry system comprising a wavefront sensor, wherein the ocular aberrometry output data comprises at least wavefront sensor data associated with an optical target monitored by the ocular aberrometry system;
determining a tear film hydration state associated with the optical target based, at least in part, on the received ocular aberrometry output data; and
determining 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
projecting, from a projection device, 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.
