PPC in lamellar cataract (A–D) and total intumescent cataract (E to H): PPC probe is collapsed and inserted into AC (A), followed by reopening, centration (B, E) and application of suction. A series of nanoelectrical pulse wave forms are delivered (F) and the probe is withdrawn from AC forming a round centred capsulotomy (C), facilitating in the bag IOL implantation (D and H). The instantaneous 360° creation of round regular capsulotomy with simultaneous suction of the liquefied cortex (F, arrow) prevents radial tears. AC, anterior chamber; IOL, intraocular lens; PPC, precision pulse capsulotomy.
