Catalytic neutralization of hydrogen peroxide
Hydrogen peroxide contact lens solutions
require the use of a catalytic disc, which is inserted or affixed in the
lens case. This disc helps to neutralise the hydrogen peroxide while
disinfecting the lenses. The lenses must be left in the solution for a minimum
of six hours. This procedure must be strictly followed to avoid
discomfort caused by residual hydrogen peroxide.
Because this method
requires a slightly larger lens case, it also means a higher consumption
of solution.
