ABSTRACT:
A system and method for reducing and removing and ophthalmic lens of a mammalian eye. The system includes a rotary lens-reducing probe device of either straight or curved configuration, said probe device comprising a tubular outer sheath through which a rotatable drive shaft extends. A rotating lens-reducing head member is positioned on the distal end of the drive shaft. The head member is configured and constructed to draw a flow of fluid and lens matter into contact therewith, thereby facilitating complete reduction of the entire lens without requiring significant axial (i.e., longitudinal) movement of the probe within the lens capsule. The distal portion of the tubular sheath is preferably configured to shield a portion of the lens-reducing head, during operation, to avoid inadvertent damage to lens capsule. Also, the distal portion of the sheath may be aimed or positioned to direct the flow of fluid and lens matter created by the rotating head in a preferred flow path within the lens capsule. The device may incorporate means for infusing and/or withdrawing fluid and/or debris into/from the eye.
