Abstract: A vitreous cutter 10 includes a plurality of vanes 14 rotatably attached within a housing 12. An inlet 16 receives pressurized fluid, which causes rotation of the vanes 14. An outlet 20 allows the pressurized fluid to exit the cutter 10. A cam 24 rotates upon rotation of the vanes 14, which causes reciprocal movement of a vitrectomy probe 28.

Abstract: A peristaltic pump 30 includes a 360° backing plate 14 and 35 and an orbiter 36 for eccentrically orbiting within the backing plate. A loop of tubing 16 surrounds the orbiter 36 and is placed between the orbiter 36 and the backing plate.

Abstract: A microkeratome cutting head assembly 10. A cutting blade 14 of the assembly 10 has a nominal length and presents a forward cutting edge 22. An applanation member 12 for applanating a cornea of an eye includes a trailing portion 18 having a curved section presenting an apex 20. The forward cutting edge 22 of the cutting blade 14 of the nominal length is positioned relative to the apex 20 so that together the forward cutting edge 22 and the apex 20 define a desired thickness of a flap 50 to be created from the cornea 48 such that the flap 50 is essentially not compressed.

Abstract: A compliant device attaching to the end of a robot arm and used in conjunction with a stereo vision system. The compliant device compensating for misalignment error in six degrees of freedom, that is x, y, z, pitch, yaw, and clocking (roll) between the end of the robot arm and a lock-on bushing when the compliant device is being inserted in a lock-on bushing. The compliant device having attached a stereo vision target providing positional feedback on the misalignment error between the lock-on bushing and the final position of the end of the robot arm to the stereo vision system.
