Abstract
The purpose of this study is to compare and assess the performance and the postoperative outcomes of torsional mode and ultrasound US mode performed in the phacoemulsification of cataract with different nuclear densities This is a randomized comparative clinical study Two groups of 75 eyes the first operated by Ozil® and the second by US were comparable in age gender cataract density corneal incision size and intraocular lens type We assessed peroperative parameters US time UST and cumulative dissipated energy CDE Postoperative outcome measures were corneal edema and final bestcorrected visual acuity The UST was significantly lower in the ozil® group for all nucleus grades 7343 s ± 83 with US vs 4602 s ± 23 with Ozil® p = 00003 The CDE was lower in the Ozil® group for grade III and IV cataract p = 0005 However no significant difference was noted for grade II cataract p = 007 Immediate postoperative corneal edema was significantly harder in the US group p = 000002 The mean one month postoperative visual acuity was 02 ± 003 logMAR and 015 ± 007 logMAR respectively in the US group and the Ozil® group p = 006 Ozil® mode seems to dissipate less energy in the eye than US mode The visual outcome at one month is comparable in the two groups
