摘要

Purpose: Multi-dimension aspiration control mode was put forward in this study. Accuracy of multi-dimension aspiration control model was compared to simple traditional pedal control model. Methods: Induced by high aspiration pressure (200～250 mmHg), hard nucleus (≥ Grade Ⅲ) of senile cataract was chopped before phacoemulsification in 170 patients (174 eyes). Ninety-one patients (94 eyes) accepted multi-dimension aspiration control model in which aspiration direction, distance and targets prevention were adjusted by phaco-tip besides traditional pedal control. Another 79 patients (80 eyes) were compared as reviewed group, aspiration of which was controlled simply by traditional pedal control. Postcapsular rupture rates (PCRR) were compared between two groups. Results: Multi-dimension control model could make the terminal effects cooperate with phacoemulsification more precisely and protect post capsular from damage (χ~2 =5.41, P < 0.02). Conclusion: Multi-dimension control model could improve the accuracy of aspiration effects and protect postcapsular from damage.
