摘要：
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.
