ABSTRACT:
An artificial tear suspension system is provided which includes bioerodible mucin-type particles, lipid-type material and aqueous-type material. The bioerodible mucin-type particles are suspended in either the lipid-type material or the aqueous-type material or both. The system provides all of the components of the natural tear film layers, and thus when administered to the eye provides an effective tear film which mimics the natural tear film.
