    en.wikipedia.org/wiki/Ophthalmic_viscosurgical...

    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.

    An OVD is a viscoelastic solution, a gel-like substance used to maintain the shape of the eye at reduced pressure as well as to protect the inside structure and tissues of the eye without interfering with the operation. [1] In 1980, D.M. Colvard made the cataract incision in the sclera, which limited induced astigmatism. [9]

    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]

    The eye will be checked to ensure the IOL remains in place, and once it has fully stabilised, after about six weeks, vision tests will be used to check whether prescription lenses are needed. [35] [8] Where the focal length of the IOL is optimised for distance vision, reading glasses will generally be needed for near focus.

  7. Viscoelasticity - Wikipedia

    en.wikipedia.org/wiki/Viscoelasticity

    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.

  8. Glaucoma surgery - Wikipedia

    en.wikipedia.org/wiki/Glaucoma_surgery

    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 ...

    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]
