An example system for tracking motion of an eye during an eye treatment includes an image capture device configured to capture a plurality of images of an eye. The system includes controller(s) including processor(s) that receive the plurality of images from the image capture device. The processor(s) implement a plurality of trackers. Each tracker is configured to detect a respective feature in the plurality of images and provide, based on the respective feature, a respective set of data relating to motion of the eye. The respective features detected by the plurality of trackers are orthogonal relative to each other and the respective sets of data provided by the plurality of trackers are independent of each other. The processor(s) coalesce the sets of data from the plurality of trackers and determine an indicator of the motion of the eye based on the coalesced sets of data.

Systems and methods for eye tracking during eye treatment

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.
