7 Claims

1. A device for quantitative assessment of orbital soft tissue restriction, comprising:

(a) a motion-generation unit, wherein the motion-generation unit comprises stacked vertical, rotational and translation motor stages;

(b) a suction cup suitable to fit a front part of an eye;

(c) a primary resistance measurement sensor, wherein the resistance measurement sensor is configured in between the motion-generation unit and the suction cup;

(d) secondary resistance measurement sensors, wherein the secondary resistance measurement sensors are linked to the vertical and rotational motor stages;

(e) a controller controlling the rotational motor stage and the translation motor stage in the motion-generation unit to generate and control a motion path of the suction cup and therewith a motion of the eye;

(f) a controller controlling a vertical excursion of the device and neutralizing force applied to globe and orbital soft tissues of the eye; and

(g) a data collection unit to collect data from the resistance measurement sensors during the execution of the motion path of the suction cup, wherein the collected data provides insight in an orbital range of motion or an orbital soft tissue resistance as a function of the motion path of the suction cup.
