Abstract

Accuracy in manual manipulation in a simulated microsurgical environment has been studied. Three vitreoretinal microsurgeons completed a series of static and dynamic tasks. Results for overall rms position error, overall maximum position error, and estimated physiological tremor amplitude were calculated. The rms amplitude of the error vector in three dimensions averaged 166 /spl mu/m in a stationary pointing task, and 2009-4506 /spl mu/m in the dynamic tasks. The maximum error vector magnitude during the stationary task averaged 408 /spl mu/m during the stationary tests, and 3531-6788 /spl mu/m in the dynamic tasks. The rms amplitude of tremor during the stationary task averaged 76-101 /spl mu/m in the three spatial coordinates, with an average vector magnitude of 156 /spl mu/m rms.
