Viscoelastic choice leaves no need to compromise

Cataract surgeons whose preferred viscoelastic is DuoVisc (Alcon), the product co-packaging 1% sodium hyaluro- nate (ProVisc) and 3% sodium hyaluronate/ 4% chrondoitin sulfate (Viscoat), appreciate its advantage in allowing use of either a cohesive viscoelastic or a dispersive agent during portions of the procedure when each is needed most.
