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.
