ABSTRACT:
An instrument (10) for accurately guiding a superior lens haptic (20) into the capsular bag to insure that both the inferior haptic (21) and superior haptic (20) are positioned within the confines of the capsular bag to effect lens centration. The instrument (10) comprises a stainless steel wire shaft (12) having a loop (16) on one end and a handle (14) on the other end. The wire has a diameter of 0.022 in. and the loop has an internal diameter of 0.6 mm and the orientation of the loop is critical. The shaft is bent at a point where it connects to the loop so that the loop, when observed from the handle, is inclined at an angle of 45 degrees to the right from the axis of the shaft and the side of the loop facing the observer is tilted downwardly from the axis of the shaft to an angle of about 45 degrees. Thus, the loop is inclined laterally and downwardly and when held in the left hand, placed inside the eye with the loop slid over the base of the superior lens haptic, the angulation of the loop points the lens haptic directly toward the equator of the capsular bag.
