Eye therapy

A system for controlling cross-linking in corneal tissue, comprising:

• a vessel that stores a cross-linking agent under O2 pressure higher than ambient pressure and provides a higher equilibrium concentration of O2 for the cross-linking agent, the cross-linking agent being saturated or supersaturated with O2;
• an applicator that applies the cross-linking agent to corneal fibrils in the corneal tissue, the saturation or supersaturation of the cross-linking agent increasing the O2 content in the corneal tissue when the applicator applies the cross-linking agent;
• and
• a light source that provides photo activating light to the corneal fibrils and activates the cross-linking agent, the activated cross-linking agent causing cross-linking in the corneal fibrils to preserve the structure of the corneal fibrils.

A system for controlling cross-linking in corneal tissue, comprising:

• a vessel that stores a gel agent under O2 pressure higher than ambient pressure and provides a higher equilibrium concentration of O2 for the gel, the gel being saturated or supersaturated with O2;
• an applicator that applies a cross-linking agent to corneal fibrils in the corneal tissue;
• and
• a light source that provides photo activating light to the corneal fibrils and activates the cross-linking agent, the cross-linking agent causing cross-linking in the corneal fibrils to preserve the structure of the corneal fibrils,
• wherein the gel is applied to the cornea with the cross-linking agent, the saturation or supersaturation of the gel increasing the O2 content in the cornea.
