<p>The present invention is characterized by a syringe (30) and a method for injecting a cell-killing substance between the capsule and the natural lens of an eye and for aspirating any of the cell-killing substance escaping from the capsule. A hollow needle (32) having a sharp distal end (60) for puncturing the capsule and positioning between the capsule and the natural lens at an angle substantially tangential to the natural lens and a proximal end, an injection chamber (44) communicating with the proximal end of the needle (62) adapted to be filled with the cell-killing substance, an aspirating tube (34) disposed concentrically around the needle having an open distal end (66) proximally spaced from the distal end of the needle for positioning adjacent the capsule when the distal end (60) of the needle has punctured and passed through the capsule and a proximal end.</p> |
