eye-surgery robot

>>High precision movements

The surgeon's movements are scaled-down, for example so that each centimeter of motion on the joystick is translated into a movement of only one millimeter at the tip of the instrument. "This greatly increases the precision of the movements", says Meenink.
Haptic feedback The master also provides haptic feedback. Ophthalmologists currently work entirely by sight – the forces used in the operation are usually too small to be felt. However Meenink's robot can 'measure' these tiny forces, which are then amplified and transmitted to the joysticks. This allows surgeons to feel the effects of their actions, which also contributes to the precision of the procedure.
