%X Purpose: To evaluate the safety and efficiency of torsional phacoemulsification on senile dense cataract    Setting: Jakarta Eye Centre, Jakarta, Indonesia    Materials & Methods: Prospective, randomized single blind clinical trial. Twenty-four eyes with hard cataract were randomly divided into 2 groups: 10 eyes had torsional (Group 1) and 14 eyes had longitudinal phacoemulsification (Group 2). Measurement of endothelial cell count (ECC), corneal thickness (CT) and flare at 1 day after the operation are the safety indicators. Effective phacoemulsification time (EPT) and balanced saline solution (BSS) used, as an efficiency indicators, was monitored on the day of surgery. p value of <0.05 was considered statistically significant.    Results: The mean ECC was lower in Group 1 [(2306.0 cell/mm2 ± 348.3 (SD)] than Group 2 [(1997.2 cell/mm2 ± 459.1 (SD)] (p>0.05). The mean CT and flare were, respectively, 601.4 µm±59.39SD) and 8.82 photoncount/sec±4.70 in Group 1; and 606.7±74.9(SD), 12.8 photoncount/sec±7.22 in Group 2 (p>0.05). Three subjects with cataract grade 5 in Group 2 had severe corneal edema. The mean EPT was 17.85 seconds±8.39 (SD) and BSS usage was 45.5 mL±8.8 (SD) in Group 1; and 33.81 seconds ±24.53 (SD), 83.6mL±46.7 SD, respectively, in Group 2. The difference was statistically significant.     Conclusions: This study indicates that torsional phacoemulsification is more efficient in patients with a hard lens nucleus. Phacoemulsification safety also could be increased and patients outcome improved with this modality.
