   early symptoms cataract

  Because in the eye rays of light into must pass a lens, if the lens stop light, or make consumers into light slants song, diffusion all can affect vision. Eyesight affected degree depends on the opacity of the site and the density of the lens (cataract maturity).

  In the bright light, the light of the eye pupil narrowing, narrow channels, more likely to stop light into cataract. Therefore, many cataract patients in bright light more poor eyesight. And the light occur around halo, glare and scattering the light. When cataract patients from the shadows into the bright environment, or in the bright lights when reading blurred vision, particularly evident. Also suffer from glaucoma and cataract patients, with shrinkage in drops of the pupil medicine for the pupil narrowing, after eyesight also will be obviously decreased.

  Located in the rear lens capsule cloudy (under) in bright light cataract for visual effect is heavy. Because the lens is very light after only road, the more likely to damage cataract vision.

For no glaucoma cataract patients, the use of the pupil expansion agent may help improve eyesight. In the bright light wear sunglasses, use reflective light and not point-blank light also can reduce the light scattering.

  Any age cataract patients all can surgery, and generally do not need to anesthesia, also need not spend the night in hospital. In the operation, the clouded lens is removed, it generally need to implant a medal plastic crystals or silicon crystal (artificial crystal), if not be artificial lens implantation, while more of the postoperative patients need to wear contact lens.
