Which system is considered most effective for removing deposits from contact lenses?

Hydrogen peroxide systems are recognized as the most effective method for removing deposits from contact lenses due to their powerful disinfecting properties and ability to break down organic materials. The mechanism involves a multi-step process where hydrogen peroxide is converted to less harmful substances, such as water and oxygen, which helps to thoroughly cleanse the lenses.

These systems utilize a catalase enzyme during the neutralization process, allowing for effective removal of protein, lipids, and other debris that can accumulate on the lenses. This is particularly important because these deposits can irritate the eye and reduce visual clarity. Hydrogen peroxide systems also typically involve a two-step disinfection system, ensuring that lenses are both cleaned and disinfected without compromising ocular health, making them ideal for individuals who wear lenses regularly.

In contrast, saline solutions do not have the ability to disinfect or remove deposits; they primarily serve as a means of storing and rinsing lenses. Soap-based cleaners can be effective in some contexts but may leave residues that are not ideal for use with contact lenses. Alcohol-based disinfectants are too harsh for lens materials and can lead to lens degradation. Hence, the hydrogen peroxide systems stand out as the superior choice for effective cleaning and disinfecting of contact lenses.
