Abstract
A system for corneal treatment includes a light source that activates cross-linking in at least one selected region of a cornea treated with a cross-linking agent. The light source delivers photoactivating light to the at least one selected region of the cornea according to a set of parameters. The system includes a controller that receives input relating to the cross-linking agent and the set of parameters. The controller includes computer-readable storage media storing: (A) program instructions for determining cross-linking resulting from reactions involving ROS including at least peroxides, superoxides, and hydroxyl radicals, and (B) program instructions for determining cross-linking from reactions not involving oxygen. The controller executes the program instructions to output a calculated amount of cross-linking in the at least one selected region of the cornea. In response to the calculated amount of cross-linking, the light source adjusts at least one value in the set of parameters.
