Abstract
Biocompatible intraocular implants include a steroid and an auxiliary agent, where the auxiliary agent is present in an amount sufficient to lessen the severity of at least one side effect compared to the use of an otherwise identical implant lacking said auxiliary agent. The steroid and the auxiliary agent may be present on the same intraocular implant or on different implants. The steroid and auxiliary agent may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. Or, the steroid may be associated with a polymeric coating having one or more openings effective to permit the steroid to be released into an external environment. The implants containing the steroid and an auxiliary agent may be placed in an eye to treat one or more ocular conditions while reducing the side effects otherwise accompanying steroid use.
