What is hyaluronic acid in contact lens solution?
It can be argued that “biomimicry” can enhance ocular surface wetting. And polymers like hyaluronic acid do just that. e problem for contact lens wear is that the front surface of a hydrogel or silicone hydrogel contact lens isn’t a biological surface. Although hyaluronic acid may be a natural wetting agent found in the eye, the front surface of a contact lens bears little relation to the front surface of the eye. e contact lens doesn’t have the eye’s mucin structure to hold biological substances like hyaluronic acid to their surfaces. In this situation, “biomimicry” doesn’t apply.
A contact lens kit may include one or more soft contact lenses stored in an ophthalmologically acceptable solution of hyaluronic acid or a salt of hyaluronic acid. A method of disinfecting a soft contact lens, storing a soft contact lens, or facilitating insertion of a soft contact lens in an eye, may include placing the soft contact lens into an ophthalmologically acceptable solution that comprises (a) hyaluronic acid or a salt of hyaluronic acid, and (b) at least one compound to disinfect, store, or facilitate insertion of the contact lens.
