Bausch + Lomb Corp. reported its U.S. launch of an ophthalmic viscosurgical device (OVD) designed to protect patients during cataract surgery. The Totalvisc viscoelastic system is a dual action chemical protection system that employs viscoelastics which have the properties of both a fluid and an elastic.
