ABSTRACT:
A method and device for delivering a drug to the cornea and anterior chamber of an eye are disclosed. A drug is entrapped in microspheres of poly(lactic acid), poly(glycolic acid), a copolymer of lactic acid and glycolic acid, poly(ethylene-vinyl acetate), or a mixture of poly(lactic acid) and poly(glycolic acid). The microspheres are combined with a hydrophilic polymer and placed in contact with the eye.
