Abstract: A system for treating an eye includes a laser light source providing photoactivating light. The system includes a scanning system to receive the photoactivating light as a laser beam and to move the laser beam over a cornea treated with a cross-linking agent. The system includes a controller that provides control signal(s) to programmatically control the laser light source and the scanning system. The control signal(s) cause the laser beam to visit region(s) of the cornea more than once according to a scan pattern and expose the region(s) to the photoactivating light. The photoactivating light causes the cross-linking agent in the exposed region(s) to react with oxygen to generate cross-linking activity in the exposed region(s). The scan pattern causes a predetermined period of time to pass between visits by the laser beam to the exposed region(s), the predetermined period of time allowing oxygen in the exposed region(s) to replenish.

Abstract: An automated process receives input tomography data and generates an optimized (customized) treatment pattern for an individual patient without relying on the physician's analysis and judgment. For example, a method for treating a cornea includes receiving tomographic data for a cornea. The method includes identifying a keratoconic defect in the cornea based on the tomographic data. The method includes segmenting the keratoconic defect into treatment zones based on predefined geometric parameters, wherein the treatment zones indicate where a cross-linking agent is to be applied on the cornea and photoactivated to treat the keratoconic defect.

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.

Abstract: 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.

Abstract: Methods employ bioresorbable corneal implants to treat corneal ectatic disorders and/or refractive errors. The corneal implants may be formed from a porous microstructure that can encourage the proliferation of endogenous keratocytes. As such, the corneal implants act as tissue scaffolds that promote tissue growth to increase the biomechanical stability and/or change the shape of the cornea. Over time, the corneal implants may resorb via hydrolysis or enzymatic breakdown, negating the risks of inflammation, scarring, or foreign body response. The corneal implants may also employ drug coating(s) to promote tissue growth.
