ABSTRACT:
A drug delivery system comprising a contact lens having dispersed therein as nanoparticles having a particle size less than about 50 nm, an ophthalmic drug nanoencapsulated in a material from which said ophthalmic drug is capable of diffusion into and migration through said contact lens and into the post-lens tear film when said contact lens is placed on the eye.
