a During the cataract surgery, the posterior capsule was damaged when half the nucleus had been excised. Three ports were created using a 27-gauge transconjunctival vitreous surgery system. b The 27-gauge vitreous cutter was pressed against the remaining fragments of nucleus while suction was applied from the vitreous body side, cutting into and extirpating the nucleus without repelling it. c The fragments of nucleus that had dropped onto the retina were picked up from the retinal surface by suction with the vitreous cutter. d Nucleus fragments that had been picked up by the suction power of the 27-gauge TDC vitreous cutter. e The suction power was maintained even while the inner shaft cutting blade was being driven at high speed. f A nucleus of around Emery-Little grade 3 hardness can be dealt with using a TDC cutter alone with a 27-gauge cutter system.

Part of the remaining nucleus was seen to have dropped into the vitreous cavity (fig. 1a). Three ports were created using a 27-gauge transconjunctival vitreous surgery system (fig. 1a). TDC cutter. The vitreous cutter settings were: cut rate, 6,000 cuts per min (cpm); suction, 600 mm Hg, and perfusion pressure, 30 mm Hg. The 27-gauge vitreous cutter was pressed against the remaining fragments of nucleus while suction was applied from the vitreous body side, cutting into and extirpating the nucleus without repelling it (fig. 1b). The fragments of nucleus that had dropped onto the retina were picked up from the retinal surface by suction with the vitreous cutter (fig. 1c). Nucleus fragments that had been picked up by the suction power of the 27-gauge TDC vitreous cutter were retained because suction power was maintained even while the inner shaft cutting blade was being driven (fig. 1d, e), enabling efficient extirpation with the vitreous cutter (fig. 1f).
