''Once you tell people there's a cure for something, the more likely they are to pressure doctors to prescribe it.'' -Robert Ehrlich, drug advertising executive.

The results of the first clinical trial of an artificial retina implanted into the eye showed that it worked well enough to allow the blind to distinguish light from dark and even to see simple objects.
Each patient had an operation to have the implant fitted over their own damaged retinas. They wore spectacles fitted with miniature video cameras, which transmitted signals to the implanted device.
All the patients could see far better with the device switched on and one of them could even tell the difference between everyday objects.
