They were originally called viscoelastic substances, or just viscoelastics. Their consistency allows the surgical instruments to move through them, but when there is low shear stress they do not flow, and retain their shape, preventing collapse of the anterior chamber. OVDs are available in several formulations which may be combined or used ...
The Canadian Journal of Ophthalmology is a peer-reviewed medical journal and the official journal of the Canadian Ophthalmological Society. It covers all aspects of ophthalmology. The journal is abstracted and indexed in Science Citation Index Expanded, Embase, MEDLINE, and Scopus. [1]
Unlike purely elastic substances, a viscoelastic substance has an elastic component and a viscous component. The viscosity of a viscoelastic substance gives the substance a strain rate dependence on time. Purely elastic materials do not dissipate energy (heat) when a load is applied, then removed.
The first issue of Investigative Ophthalmology was published in January 1962, with Bernard Becker, MD, as the Executive Editor. The title was changed to Investigative Ophthalmology & Visual Science in 1977. [2] Abstracts from the ARVO Annual Meeting have been published as an issue of IOVS since 1977. [2]
It forms a viscoelastic solution in water. Mechanical protection for tissues (iris, retina) and cell layers (corneal, endothelium, and epithelium) are provided by the high viscosity of the solution. Elasticity of the solution assists in absorbing mechanical stress and providing a protective buffer for tissues. In facilitating wound healing, it ...
