Abstract
The present invention relates to compositions which maintain the structural integrity of the anterior chamber of the eye during ophthalmologic surgery, thereby protecting the tissues that form and line the anterior segment from potential damage and simultaneously providing sustained delivery of a miotic or mydriatic agent. The present invention provides for compositions which comprise a viscoelastic polymer, wherein sustained release of a miotic or mydriatic agent is mediated by ionic interactions, as well as for compositions wherein sustained release of a miotic or mydriatic agent is mediated by microcapsules or copolymer micelles.
Claims5
A composition for intracameral use in ophthalmologic surgery comprising biodegradable microcapsules that maintain the structural integrity of the eye which comprise a viscoelastic polymer and an agent selected from the group consisting of miotic agents and mydriatic agents.
