A device used to measure intraocular pressure within a patient's eye includes a probe typically having an end to which is attached a resilient member with a hollow interior that decreases in volume as the member is pressed against the eye. The greater the intraocular pressure within an eye, the more the volume decreases. A liquid moves in response to this change and this movement is detected to signal if the intraocular pressure is at a safe level.
