Abstract Details


To compare the efficiency, safety and predictability of two fluidics sittings in hard cataract using the Centurion Ozil torsional phaco.


Expert eye centre in Cairo, Egypt


Chop efficiency using the centurion (Alcon) phaco machine. 100 cataracous eyes of grade 3 and four LOCS classification,divided into two groups, group 1 included 50 eyes operated using moderate fluidics parameters of 30 cc/min flow rate FR, 400 mmhg linear vacuum and 50mmhg intraocular pressure IOP. Group 2 included 50 eyes operated using high fluidics parameters of 50 cc/min flow rate FR, 600 mmhg linear vacuum and 50mmhg IOP Comparing the holding efficiency during chopping, anterior chamber AC stability and Consumed energy.


Group one showed better efficiency in holding the nucleus e less number of nucleus slipping from the phaco tip. 0.3+_ 0.1 in comparison to group two 1.7 +_ 0.8 , both groups stable AC. E no pupil diameter changes. Cumulative dissipated energy was less in group one 6.9+_2.8 in comparison to 8.1+_3.1 in group two.


Moderate fluidics showed more safety, efficiency and predictability in denser nuclear cataract more
