Abstract: An eye surgery apparatus has imaging optics for generating an observation image of a patient eye. A device determines the azimuthal orientation of the patient eye with respect to a reference which is fixed with respect to the patient eye. The device includes a display unit for simultaneously displaying a section of an observation image of the eye and a reference image thereof. An input interface permits an observer to move the displayed section of the observation image relative to the displayed section of the reference image. A measuring system determines the azimuthal orientation of the observation image and reference image. A computer program calculates the center of the limbus of the observation image and reference image. The display unit displays the pixels of the observation image of the patient eye with polar coordinates. The pixels of the reference image of the patient eye are displayed with polar coordinates.

Abstract: A noninvasive remote parameter sensor and sensing method is provided that is particularly suited for the remote monitoring of skin temperature. The sensor and sensing method utilize luminescence-based sensors that are non-toxic and non-irritating to the skin. The sensor preferably utilizes one or more types of fluorophores that are embedded in a soft hydrogel. The sensor is illuminated with excitation light, and temperature is monitored by detecting and analyzing the emission light from the fluorophores. Because a soft hydrogel is used, the sensor can be gently wiped off the skin at the conclusion of temperature measurements.
