Intracapsular aspiration.
Through a 2-mm. limbal incision, the aspiration of the lens is accomplished; this assures a strong eye immediately after operation. It frees the eye from the complications associated with the large incision required for linear extraction of the lens. Intracapsular aspiration of the entire lens cortex and nucleus is performed through a 2-mm. hole in the anterior capsule near the equator. Posterior synechiae are prevented by leaving the anterior capsule intact and in apposition with the posterior iris surface, assuring a round, mobile pupil. An axial 5-mm. hole placed through the collapsed anterior and posterior lens capsule usually remains free of secondary membrane formation, obviating the need for further surgery. The complication of vitreous presentation in the corneoscleral incision is managed by performing an anterior vitrectomy with an instrument that cuts and aspirates the vitreous.
