Molecular hydrogen effectively heals the alkali-burned cornea via suppression of oxidative stress, decreases the inflammation in the anterior eye segment and prevents corneal neovascularization.
The alkali-burn of the anterior eye segment evokes oxidative stress. The antioxidant mechanisms are exhausted leading to the antioxidant/prooxidant imbalance which is immediately followed by the protease/antiprotease imbalance. This situation results in the excessive inflammation. When the molecular hydrogen is dropped on the anterior eye surface early after the injury, it suppresses oxidative stress and thus decreases the inflammation and promotes the healing process.

The healing of the rabbit eye after alkali burn after the treatment with buffer or buffer with H2. The cornea healed with H2 is transparent with no sign of neovascularization (day 20). The treatment with H2 significantly decreased expression of vascular endothelial growth factor, which is characteristic for neovascularization.
