The utility model provides a cataract prevention and treatment instrument which comprises a pulse voltage amplitude adjusting circuit, a pulse frequency adjusting circuit, an amplifying output circuit, a time delay circuit and a power supply. The pulse voltage amplitude adjusting circuit is electrically connected with the pulse frequency adjusting circuit electrically connected with the time delay circuit electrically connected with the amplifying output circuit. The time delay circuit comprises a chip, a potentiometer, a diode, a resistor, a triode, an inductor, a switch and a node. The instrument can be automatically closed in a delaying mode to prevent a user from acupuncture point fatigue and protect the user. The inductance of the amplifying output circuit is improved from first-stage amplifying to second-stage amplifying and enables pulse waveform (symmetrical sharp wave) to be ideal, positive and negative peak-to-peak value voltage is increased appropriately, and a prevention and treatment effect is be
