Abstract
A system for removing the lens from an eye of a mammal, including a lens-removal device having a probe for penetrating the lens capsule. The probe includes a sheath that shields a rotating impeller at all times, with the impeller being pneumatically actuated to advance to a lens removal position within the sheath. The impeller is pneumatically rotated using a turbine mechanism within a handle for the probe. Irrigation and aspiration are provided to facilitate removal of the lens tissue. The turbine is driven with pulsed air to prevent stiction. A purge/protection cap helps remove air bubbles from the system prior to use and protects the delicate impeller during transport. An operating system is also provided with a foot pedal actuator.
