entirely without viscoelastics. Within just a few years this group of substances has enlarged the field of ophthalmic surgery enormously. Many procedures have be- come safer and simpler and other techniques could only be developed because of the availability of visco elastics. Especially cataract surgery and implantation
The ideal viscoelastic substance should be viscous enough to prevent collapse of anterior chamber. It should be cohesive also to be removed easily from the anterior chamber but not so cohesive that it is aspirated during irrigation and aspiration, providing no protection to the corneal endothelial cells2. OVDs are generally

Abstract: Among viscoelastic substances, sodium hyaluronate has become the most popular for intraocular surgeries since the introduction of Healon® (sodium hyaluronate 1%, 4 ? 106 daltons) in. 1979. This review focuses on the recent development of a new generation of sodium hyaluronate agents with new rheologic

Methods. Forty eyes of 36 adult patients were enrolled in this randomized, double- masked clinical trial. They were randomly assigned to receive either DV or AP during phacoemulsification. Both the patients and the evaluators were masked as to which viscoelastic was used during the surgery. The main outcome measures

Ophthalmic viscosurgical devices (OVDs, previ- ously known as viscoelastics (terms which will be used interchangeably in this review) were originally devices in search of a use. Sodium hyaluronate viscoelastic solutions were tried as vitreous substitutes as early as the 1960s, with varying success. But their eventual primary.
