Multi-dimension aspiration control mode in phacoemulsification.

Abstract

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 (> OR = 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 ..
