  • Publication number: 20230285279
    Abstract: Biocompatible intraocular implants include an alpha-2 adrenergic receptor agonist and a polymer associated with the alpha-2 adrenergic receptor agonist to facilitate release of the alpha-2 adrenergic receptor agonist into an eye for an extended period of time. The alpha-2 adrenergic receptor agonist may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. The implants can be placed in an eye to treat one or more ocular conditions, such as an ocular vasculopathy or glaucoma, including reduction of an elevated intraocular pressure.

  • Publication number: 20160243032
    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.
