Cataract

Cataracts are the opaque, or milky, areas that can form in part or all of the crystaline lens of the eye. They often start with only a slight disturbance of normal vision, often going unnoticed for years, and can slowly increase in opacity until they completely interfere with vision. Some of the early effects of a cataract are a decrease in contrast sensitivity and color intensity, but eventually they also decrease visual acuity.

Cataract Surgery and AMD

The AREDS study, funded by the National Eye Institute, showed that cataract surgery improved vision in AMD patients. 1,939 eyes were evaluated for visual acuity after cataract surgery. After one year, the 865 eyes that were still available for study, showed significant statistical gains.

Lens

The lens is a dense, transparent structure made of proteins, located just behind the iris and pupil. Its curvature and density cause light waves to bend as they travel through the lens. After passing through the lens, the light waves converge and project an inverted image on the retina. The retina changes the light waves to electric impulses that then travel along the optic nerve to the brain. This entire series of events results in a visual and understandable representation of light and color.
