Suction posterior capsulorhexis.
A technique for creating a posterior capsulorhexis during phacoemulsification is presented. It can be used in cases with posterior capsule tears or opacities. The free edge of the capsule is grasped with suction using a 2 mL syringe and a 27 gauge Rycroft cannula introduced via the paracentesis. The edge is then manipulated to produce a continuous curvilinear opening in the posterior capsule. The combination of a closed eye plus the use of a viscoelastic agent in the anterior chamber and capsular bag minimizes the possibility of vitreous prolapse during the maneuver. Occlusion of the cannula tip by the posterior capsule reduces the risk of vitreous aspiration. In-the-bag intraocular lens implantation is readily achieved.
