An improved tenometer provides for a bellows and a stepper motor to pressurize the interior of a probe in the barrel into which the probe is fitted for moving the probe outward towards a patient's eye. The device also includes a laser for improved centering of the patient's eye over the eye piece, and a safety detection device for terminating operation of the tenometer if the probe fails to move along the barrel after a given amount of pressure is applied to the interior of the barrel and the probe. A rotatable occluder near the head rest for blocking the eye not being tested and a computer in the instrument records the eye being tested and the test results. |
