    Abstract: To treat corneal ectatic disorders, systems and methods can precisely apply photoactivating light to specified areas of a cornea treated with a cross-linking agent. An example system includes a light source that provides a photoactivating light to photoactivate a cross-linking agent applied to an eye. The system includes optical element(s) that transmit the photoactivating light to the eye according to a pattern defined by a plurality of treatment zones. The treatment zones are delivered to different respective areas on the eye. The plurality of treatment zones includes at least a first treatment zone and a second treatment zone. The first treatment zone provides a first dose of the photoactivating light. The second treatment zone provides a second dose of the photoactivating light. The first dose is greater than the second dose. The first treatment zone is disposed within an inner boundary of the second treatment zone.

    Abstract: Formulations, are used for eye treatments, e.g., cross-linking treatments. For example, a therapeutic formulation includes a photosensitizer and delivery agent(s), wherein the delivery agent(s) include at least one of: anesthetic agent(s), analgesic agent(s), tonicity agent(s), or shear-thinning, or viscosity-increasing agent(s). In another example, a method includes applying preparatory formulation(s) to increase a permeability of a corneal epithelium, and applying therapeutic formulation(s) to the epithelium, where the preparatory formulation(s) include zinc metalloproteinase, copper metalloproteinase, papain, bromelain, actinidin, ficain, N-acetylcysteine, ambroxol, carbocisteine, and/or erdosteine. In yet another example, a method includes applying therapeutic formulation(s) to a corneal epithelium to deliver the therapeutic formulation(s) to a stroma, and applying enhancement formulation(s) to the epithelium in response to applying the therapeutic formulation(s), where: the enhancement formulation(s) remove the therapeutic formulation(s) from the epithelium; close tight junctions of the epithelium; promote oxidation for the therapeutic agent(s); and/or further deliver the therapeutic formulation(s) to the stroma.
