dc.description.abstract | BACKGROUND AND OBJECTIVE: To evaluate the amount Of ultrasound energy used, corneal endothelial cell loss, and central corneal thickness using the phaco-chop and stop-and-chop techniques for cataracts with different degrees of nuclear density. PATIENTS AND METHODS: One hundred two eyes of 51 patients with bilateral senile cataract were included. Each eye was randomly assigned to have either phaco-chop or stop-and-chop nucleofractis during phacoemulsification. The groups were divided into two Subgroups according to the nuclear density. The effective phacoemulsification time, endothelial cell density, and central corneal thickness were analyzed. RESULTS: The mean effective phacoemulsification time was similar between the groups In moderately dense nuclei (2.17 +/- 1.33 vs 1.33 +/- 1.05 seconds; P = .41). However, the phaco-chop technique required less effective phacoemulsification time than the stop-and-chop technique in dense nuclei (3.86 +/- 4.18 vs 6.70 +/- 5.43 seconds; P = .01). The endothelial cell loss and the central corneal thickness did not vary significantly between the groups. CONCLUSION: The phaco-chop technique requires lower ultrasound energy for nuclear management than the stop-and-chop technique in dense cataracts and the resulting endothelial loss was similar in both techniques. | - |
