A comparative study was made between group (A) which included 30eyes who had phacoemulsification using the ‘bevel down quick chop’technique and group (B) which included 30 eyes who hadphacoemulsification using the ‘stop and chop ‘ technique. The two groupswere compared in terms of equivalent ultrasound time, total energyconsumption, the effect on the corneal endothelium efficiency in differentgrades of nuclear hardness, the effect on corneal wound burn and surgicallyinduced astigmatism.In the ‘quick chop’ group, the mean equivalentultrasound time was 15.93 seconds and the mean total energy consumed was1704.51 joules. In the ‘stop and chop group, the mean equivalent ultrasoundtime was 27 seconds and the mean total energy consumed was 2889 joules.The mean endothelial cell loss after 3 postoperative months was 279cells/mm2 (11.07%) in the ‘quick chop’ group compared to 407 cells/mm2(16.08%) in the ‘stop and chop’ group. The two groups had similar effectson surgically induced astigmatism with a mean value of 0.874 D in the‘quick chop’ group and 0.75 D in the ‘stop and chop’ group. We come toconclude that the ‘quick chop’ technique was effective in reducing theequivalent phaco time, total energy utilized and corneal endothelial cell lossin different grades of nuclear hardness as compared to ‘stop and chop’.
