  • Publication number: 20220401356
    Abstract: Methods of treating an eye for an ocular condition such as placing a composite depot comprising a xerogel with embedded degradable particles into an anterior chamber of an eye to deliver a therapeutic agent. The xerogel is a hydrogel after exposure to intraocular fluid and is degradable. The degradable particles comprise the therapeutic agent and hydrolytically degrade in the anterior chamber to provide a controlled release of the therapeutic agent into the eye. Materials and processes for making depots are provided as well as alternative methods of their use.

  • Publication number: 20220370419
    Abstract: Drug delivery involving hydrogels as used for various medical conditions, and includes hydrogels formed in an eye with extended drug release times. An embodiment of the invention is a method of delivering a therapeutic agent to a tissue comprising forming a hydrogel in situ in an eye with a therapeutic agent dispersed in the hydrogel, the agent having a low solubility in water. The agent may be essentially insoluble in water. The hydrogel may be made so that 50% to 100% w/w of the agent is released when the hydrogel is from 100% to 50% persistent, with the persistence being a measure of the dry weight of the hydrogel relative to an initial dry weight of the hydrogel.
