Abstract
Biocompatible intraocular microspheres can include an active agent and a biodegradable polymer that is effective to facilitate release of the active agent into the vitreous of an eye for an extended period of time. The therapeutic agent of the microsphere can be associated with a biodegradable polymer matrix and can be made by crystallizing the active agent in the matrix. the resulting biodegradable microspheres can be placed into an eye to treat or reduce the occurrence of one or more ocular conditions.
