Sonography Quotes

The eyes have been used to signify a perverse capacity - honed to perfection in the history of science tied to militarism, capitalism, colonialism, and male supremacy - to distance the knowing subject from everybody and everything in the interests of unfettered power. The instruments of visualization in multinationalist, postmodernist culture have compounded these meanings of dis-embodiment. The visualizing technologies are without apparent limit; the eye of any ordinary primate like us can be endlessly enhanced by sonography systems, magnetic resonance imaging, artificial intelligence-linked graphic manipulation systems, scanning electron microscopes, computer-aided tomography scanners, colour enhancement techniques, satellite surveillance systems, home and office VDTs, cameras for every purpose from filming the mucous membrane lining the gut cavity of a marine worm living in the vent gases on a fault between continental plates to mapping a planetary hemisphere elsewhere in the solar system. Vision in this technological feast becomes unregulated gluttony; all perspective gives way to infinitely mobile vision, which no longer seems just mythically about the god-trick of seeing everything from nowhere, but to have put the myth into ordinary practice. And like the god-trick, this eye fucks the world to make techno-monsters. Zoe Sofoulis (1988) calls this the cannibal-eye of masculinist extra-terrestrial projects for excremental second birthing.

Cataract Treatment Advanced by Laser Eye Surgery It is estimated that half of individuals aged 65 and above will grow a cataract at some period in their life. A cataract is an eye condition that may be hazardous to your eyesight. In a healthy eye, there's a clear lens which enables you to focus. For those who have a cataract, the lens slowly deteriorates over a long period of time. Your vision can be blurry as the cataract develops, until the whole-of the lens is muddy. Your sight will slowly get worse, becoming blurry or misty, which makes it tough to see clearly. Cataracts can occur at any age but generally develop as you get older. Cataract surgery involves removing the cataract by emulsifying the lens by sonography and replacing it with a small plastic lens. This artificial lens is then stabilised within your natural lens that was held by the same lens capsule. The results restore clear vision and generally wholly remove the significance of reading glasses. However, years following the surgery, patients can occasionally experience clouding of their sight again. Vision can become blurred and lots of patients have issues with glare and bright lights. What is truly happening is a thickening of the lens capsule that holds the artificial lens. Medically this is known as Posterior Lens Capsule Opacification. This thickening of the lens capsule occurs in the back, meaning natural lens cells develop across the rear of the lens. These cells are sometimes left behind subsequent cataract surgery, causing problems with the light entering the-eye and hence problems with your vision. Laser Eye getlasereyesurgery.co.uk y Treatment Lasers are beams of power which may be targeted quite correctly. Nowadays the technology will be used increasingly for the purpose of rectifying the vision of patients after cataract operation. The YAG laser is a focused laser with really low energy levels and can be used to cut away a small circle shaped area in the lens capsule which enables light to once again pass through to the rear of the artificial lens. A proportion of the lens capsule is retained in order to keep the lens in place, but removes enough of the cells to let the light to the retina. If you want to read more information, please Click Here
