Abstract
An ophthalmic device and system for measuring relative pressure of fluid inside an ocular globe includes an elongated surgical instrument which is adapted to penetrate the ocular globe. A fluid pressure transducer is mounted on the instrument in a position to communicate with fluid inside the ocular globe and generate signals in response to pressure changes in the fluid. The signal is transmitted external of the instrument to a pump or other fluid transfer device which is operatively connected to the transducer for receiving the signals and supplying or removing fluid from the ocular globe in response to predetermined signals. A conduit is operatively connected to the fluid transfer device and adapted to communicate with the interior of the ocular globe through which fluid can flow between the fluid transfer device and the ocular globe.
