Abstract:
In a corneal measurement system, an optical element focuses an excitation light to an area of corneal tissue at a selected depth. In response, a fluorescing agent applied to the cornea generates a fluorescence emission. An aperture of a pinhole structure selectively transmits the fluorescence emission from the area of corneal tissue at the selected depth. A detector captures the selected fluorescence emission transmitted by the aperture and communicates information relating to a measurement of the selected fluorescence emission captured by the detector. A controller receives the information from the detector and determines a measurement of the fluorescing agent in the area of corneal tissue at the selected depth. The system may include a scan mechanism that causes the optical element to scan the cornea at a plurality of depths, and the controller may determine a measurement of the fluorescing agent in the cornea as a function of depth.

Claim (Index 12):
A measurement system for a cornea, comprising:\n a light source configured to emit an incidence light; at least one optical element positioned to receive the incidence light from the light source and configured to focus the incidence light to an area of corneal tissue at a selected depth of the cornea, the area of corneal tissue reflecting the incidence light; a scan mechanism configured to cause the at least one optical element to scan the cornea at a plurality of depths and to focus the incidence light on a respective area of corneal tissue at each depth, the plurality of depths extending from an anterior surface of the cornea to a posterior surface of the cornea; a pinhole structure including an aperture, the pinhole structure positioned to receive, for each depth, the reflected light from the respective area of corneal tissue, the aperture of the pinhole structure configured, for each depth, to selectively transmit the reflected light from the respective area of corneal tissue; a detector positioned to capture the selected reflected light transmitted by the aperture for each depth and configured to communicate, for each depth, information relating to a measurement of the selected reflected light captured by the detector; and a controller communicatively coupled to the detector and configured to receive the information from the detector for each depth and to determine, based on the information for the plurality of depths, at least one of a location of the posterior surface, a distance between the anterior surface and the posterior surface, or a location of a sub-corneal interface.
