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.
