  • Patent number: 8771722
    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.

  • Publication number: 20140038972
    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: 20140031408
    Abstract: Biocompatible intraocular implants include a tyrosine kinase inhibitor and a biodegradable polymer that is effective to facilitate release of the tyrosine kinase inhibitor into the vitreous of an eye for an extended period of time. The therapeutic agents of the implants may be associated with a biodegradable polymer matrix, such as a matrix that is substantially free of a polyvinyl alcohol. The implants can be placed in an eye to treat or reduce the occurrence of one or more ocular conditions.

  • Publication number: 20120276186
    Abstract: The present invention provides a sustained release, biodegradable intraocular latanoprost implant for reducing elevated intraocular pressure in an individual in need thereof. The implant can be configured as a film (e.g., a rolled film) or extruded filament, either of which can be inserted into the eye of the individual to provide for extended release of latanoprost for several days. Upon insertion into the eye, a rolled film may unroll to provide a film having a high surface area to volume ratio for drug diffusion.
