In this study we have compared the one chop nucleotomy technique (one of the chopping techniques) with the divide and conquer technique (one of the nuclear cracking techniques). The results were recorded including their effects on the corneal endothelium and the corneal thickness. Equivalent phaco time (EPT), total energy used, intra-operative and postoperative complications were also recorded. EPT and total energy were less in the phaco one-chop technique with statistically significant differences.
