The groupmainly consists of solid ophthalmic preparations, in a lesser extent there are systems developedfromhydrogels, colloidal carriers, etc.The present review lists both insoluble ophthalmic therapeuticsystems and those soluble inwater (degradable, erodible). Insoluble systems includemembrane–controlledophthalmic therapeutic systems (e.g. Ocusert®), therapeutic eye lenses, eye implants, andother insoluble preparations. In the group of soluble preparations, topical inserts and systems aredescribed, which are introduced into eye tissues as implants or injections.
