PULLBACK (Little Maneurver)

PULLBACK TECHNIQUE To ‘‘rescue’’ the capsulorhexis, the tear must be redirected centrally and back to the desired circumferential path. The first step in rescuing the tear , is to fill the chamber completely with an OVD. The force applied to the capsule flap is then reversed in direction but maintained in the plane of the anterior capsule. To reverse the force, it is necessary to first unfold the capsule flap so it lies flat against the lens cortex, as it did prior to being torn Force can then be applied with the capsule forceps holding the capsule flap as near to the root of the tear as possible and pulling backward, along the circumferential path of the completed portion of the capsulorhexis. Traction should be applied in the horizontal plane of the capsule, not upward. The initial pull should be circumferentially backward, and then, while holding the flap under tension, directed more centrally to initiate the tear. The tear will uniformly and predictably propagate toward the center of the capsule
