To evaluate the effect of a high-vacuum setting versus a low-vacuum setting on the efficiency of phacoemulsification at low fluidic parameters.
Fyodorov Eye Microsurgery Federal State Institution, Novosibirsk Branch, Russia
Sixty eight patients with cataract were included in the analysis. Phacoemulsification was performed using Centurion with monitored forced infusion. The cataractous lens was split into 2 heminuclei using the stop-and-chop technique. In the first heminucleus, phacoemulsification and aspiration used a high-vacuum setting (500 mm Hg). In the other heminucleus, a low-vacuum setting (300 mm Hg). The order of using the high and low vacuum settings alternated. Intraocular pressure levels was set 30 mm Hg, aspiration - at 20 mL/min, and torsional power - at 50%. The main outcome measures were cumulative dissipated energy (CDE) and active heminucleus removal time.
The active heminucleus removal time and CDE were lower with the high-vacuum setting than with the low-vacuum setting
Phacoemulsification machine with monitored forced infusion allows to safely and efficiently perform cataract surgery using high vacuum setting at low fluidic parameters.
