SYSTEMS AND METHODS FOR DETERMINING CROSS-LINKING DISTRIBUTION IN A CORNEA AND/OR STRUCTURAL CHARACTERISTICS OF A CORNEA
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.

Systems for incising tissue
An elongate electrode is supported between two arms and configured to flex and generate plasma to incise tissue. Each of the arms is configured to penetrate tissue with the electrode supported therebetween to form a pocket with an incision. Each arm may comprise a distal tip shaped to penetrate tissue, and an internal curved structure such as a track is shaped to allow the electrode to slide over the curved structure while the electrode is tensioned. The internal curved structure may comprise an electrically insulating material that provides electrical insulation to the tensioned sliding electrode. An opening formed in a lumen allows the electrode to extended between the curved structure and the exposed portion of the electrode suspended between the two arms. The separation distance between the two arms can be adjusted to vary an exposed length of the electrode to create a pocket incision of varying width.
SYSTEMS AND METHODS FOR EYE TRACKING DURING EYE TREATMENT
A corneal cross-linking system includes a light source configured to emit a photoactivating light. The system includes a spatial light modulator configured to receive the photoactivating light from the light source and provide a pixelated illumination. The spatial light modulator defines a maximum area for the pixelated illumination. The system includes a controller configured to cause the spatial light modulator to project a first pixelated illumination onto the cornea to photoactivate a cross-linking agent applied to a treatment area. The first pixelated illumination has an area that is smaller than the maximum area defined by the spatial light modulator. The controller is configured to determine movement of the cornea. In response to the movement, the controller controls the spatial light modulator to project a second pixelated illumination to the treatment area based on a translation and/or transformation of the first pixelated illumination to continue photoactivating the cross-linking agent.
