Ophthalmic viscosurgical devices (OVDs) are a class of clear gel-like material used in eye surgery to maintain the volume and shape of the anterior chamber of the eye, and protect the intraocular tissues during the procedure. They were originally called viscoelastic substances, or just viscoelastics.
The association was established in Washington, D.C., in 1928 as the Association for Research in Ophthalmology (ARO). In May 1970, it was renamed to its current name to reflect its broader scope. [2] [3] As of 2019, it has almost 12,000 members from 75 different countries.
The journal was established as an official publication of the Association for Research in Ophthalmology (later renamed the Association for Research in Vision and Ophthalmology). The first issue of Investigative Ophthalmology was published in January 1962, with Bernard Becker, MD, as the Executive Editor.
In August 2007 the company donated $2.5 million to UC-Irvine's Department of Ophthalmology to boost the university's planned Eye Institute. [10] On February 26, 2009, Abbott Laboratories announced that it had completed its acquisition of Advanced Medical Optics (AMO) in a $2.8 billion deal. AMO had become a wholly owned subsidiary of Abbott and ...
The human eye is an organ which reacts to light for several purposes. As a conscious sense organ, the eye allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors. [3]
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.
Researchers in vision science can be called vision scientists, especially if their research spans some of the science's many disciplines. Vision science encompasses all studies of vision, such as how human and non-human organisms process visual information, how conscious visual perception works in humans, how to exploit visual perception for ...
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
