Abstract

Presented is a device for use in a surgical procedure on an eye. The device includes an elongated member that includes a first elongated portion, a second elongated portion, and hook portion. The first elongated portion includes a proximal end and a distal end. The second elongated portion includes a proximal end and a distal end. The proximal end of the second elongated portion is coupled to the distal end of the first elongated portion. The second elongated portion extends from the first elongated portion at an angle to the longitudinal axis of the first elongated portion. The hook portion includes a proximal end and a distal end. The proximal end of the hook portion is coupled to the distal end of the second elongated member.

 a hook portion comprising a proximal end and a distal end, the proximal end of the hook portion being coupled to the distal end of the second elongated member. 
   
     
     
         2 . The device according to  claim 1 , wherein the second elongated portion is straight. 
     
     
         3 . The device according to  claim 1 , wherein the second elongated portion is curved. 
     
     
         4 . The device according to  claim 1 , wherein the angle is between 10 and 75 degrees. 
     
     
         5 . The device according to  claim 1 , wherein the overall length of the device is between 5 and 30 millimeters. 
     
     
         6 . The device according to  claim 1 , wherein the hook is curved. 
     
     
         7 . The device according to  claim 1 , wherein the hook is bent at an acute angle. 
     
     
         8 . The device according to  claim 1 , wherein the hook is bent at two locations along its length. 
     
     
         9 . The device according to  claim 1 , further comprising a sleeve disposed around the first elongated portion. 
     
     
         10 . The device according to  claim 1 , wherein the distal end of the hook comprises a rounded or semi-rounded tip. 
     
     
         11 . The device according to  claim 1 , wherein the outer surface of the first elongated portion comprises a plurality of bumps disposed along its length. 
     
     
         12 . The device according to  claim 1 , wherein the cross-section of the device is at least one of square, rectangular, oval, hexagonal, octagonal, and circular. 
     
     
         13 . The device according to  claim 1  further comprising another hook portion comprising a proximal end and a distal end, the proximal end of the hook portion being coupled to the distal end of the second elongated member. 
     
     
         14 . The device of  claim 1 , wherein the first elongated portion has a cross-section different from the second elongated portion. 
     
     
         15 . The device of  claim 1 , wherein the hook portion has a cross-section different from the second elongated portion. 
     
     
         16 . A method of performing a surgical procedure on an eye comprising:
 making an incision in the cornea of an eye; and   inserting into the eye through the incision, and retracting the iris with, a device according to  claim 1 .
