ABSTRACT:
A bioactive agent delivery system comprising an optically transparent contact lens having dispersed therein (1) an ophthalmically bioactive agent capable of diffusion through the contact lens and into the post-lens tear film when placed on the eye and (2) associated with the bioactive agent, an ophthalmically compatible polymeric surfactant in an amount sufficient to slow the rate of migration of the bioactive agent through the contact lens.
