Abstract

A system for removing cells from an interior portion of an eye, including a continuous passageway adapted to pass a fluid therethrough. A first cutting device is coupled to an exterior portion of the continuous passageway for dislodging cells from the interior portion of the eye. The first cutting device moves relative to the exterior portion of the continuous passageway due to the passing of the fluid through the continuous passageway.

       13 . An instrument according to  claim 11 , wherein: 
 said first tube is adapted to rotate about said second and third tubes.    
   
   
       14 . An instrument according to  claim 11  wherein: 
 said third tube is adapted to insert a heated solution into said inflatable instrument to inflate said inflatable instrument.    
   
   
       15 . An instrument according to  claim 11 , wherein: 
 said inflatable instrument includes a brush.    
   
   
       16 . A method for removing cells from inside of an eye, the method comprising the steps of: 
 inserting into said eye a first instrument having a surface which contacts and dislodges cells from an interior portion of the eye;    inserting into said eye a second instrument having a first tube adapted to irrigate a fluid;    inserting into said eye a third instrument having a second tube adapted to aspirate said fluid and cells from inside of said eye;    irrigating said fluid through said first tube to dislodge cells from a portion inside said eye; and    aspirating said fluid and cells from inside said eye through said second tube.    
   
   
       17 . A method according to  claim 16 , further comprising the step of: 
 creating at least one incision in a surface of said eye; and    wherein said inserting steps insert said second and third instruments into the same said incision or different incisions in said surface of said eye.    
   
   
       18 . A method according to  claim 16 , wherein: 
 said inserting steps insert said second and third instruments into a capsule of said lens of said eye.    
   
   
       19 . A method according to  claim 16 , wherein: 
 said inserting steps insert said second and third instruments through a cornea and an anterior chamber of said eye.    
   
   
       20 . A method according to  claim 16 , wherein:
