What can cause epithelial damage regarding hydrogen peroxide cleaning solutions?

Improper neutralization is a significant factor that can lead to epithelial damage when using hydrogen peroxide cleaning solutions. After cleaning, it is essential to neutralize any residual hydrogen peroxide effectively. If this neutralization process is not properly executed, the leftover hydrogen peroxide can remain active and, over time, may cause irritation or damage to the sensitive epithelial cells in the eye, particularly in contact lens wearers.

The importance of neutralization lies in the fact that hydrogen peroxide is a strong oxidizing agent. In high concentrations, it can damage biological tissues, leading to symptoms such as redness, discomfort, or even more severe complications with prolonged exposure. Ensuring that all traces of hydrogen peroxide are neutralized protects the epithelial layer of the eye from oxidative stress and potential injury. Therefore, thorough neutralization is critical in preventing epithelial damage in individuals using hydrogen peroxide-based cleaning solutions for their contact lenses.
