19. A system for removing cells from an interior of an eye, comprising:
-
an instrument adapted to pass through an incision in an eye and having a surface adapted to contact and dislodge cells from said interior of the eye; said instrument including a central axis, a continuous passageway having a first tube portion, a second tube portion, and a substantially U-shaped end portion extending between said first tube portion and second tube portion, a housing, and a component for imparting fluid circulation through said continuous passageway; said first tube portion adapted for infusing a fluid into the eye to dislodge at least some of the cells therein, said second tube for aspirating fluid and dislodging at least some of the cells out the eye; said U-shaped end portion having at least one aperture adapted to allow fluid to pass between the interior of the eye and said continuous passageway; said housing having an upper and a lower portion, said continuous passageway extending through said upper portion, said lower portion having therein a tank system in fluid communication with said continuous passageway; at least one rotatable member coupled to said continuous passageway; whereby said rotatable member induces further fluid circulation facilitating the dislodging of at least some of the cells from the interior of the eye. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
