Influence of age on the transparency of the lens in normals: a population study with help of the Lens Opacity Meter 701.
The Lens Opacity Meter 701 measures the lens density quantifying the back light scatter of the lens. The instrument emits a modulated dark-red beam which runs along the optic axis of the lens. The stray light is converted into an electrical impulse which is displayed and printed using a numerical scale. The lens density in a normal population was investigated with this instrument in order to study the influence of age on the opacification process.
