Visco-Elastics, Intraocular

Intraocular viscoelastics—more formally recognized by medical authorities and standards bodies as ophthalmic viscosurgical devices (OVDs)—are clear, gel-like surgical adjuvants composed of biocompatible polymers such as sodium hyaluronate, chondroitin sulfate, or hydroxypropyl methylcellulose Rather than exerting a systemic pharmacological effect, they function primarily through their rheological and physical properties to maintain anterior chamber depth, compartmentalize intraocular spaces, and...

Intraocular viscoelastics—more formally recognized by medical authorities and standards bodies as ophthalmic viscosurgical devices (OVDs)—are clear, gel-like surgical adjuvants composed of biocompatible polymers such as sodium hyaluronate, chondroitin sulfate, or hydroxypropyl methylcellulose These agents are primarily indicated for anterior segment and intraocular procedures, most notably cataract extraction, intraocular lens implantation, corneal transplantation, and glaucoma filtering surgeri...

Rather than exerting a systemic pharmacological effect, they function primarily through their rheological and physical properties to maintain anterior chamber depth, compartmentalize intraocular spaces, and cushion delicate tissues such as the corneal endothelium from mechanical trauma during operative maneuvers
