Clinal Assessment of the White Star[○R] Power Control System for Phacoemulsification

Purpose: To compare the clinical efficacy of phacomulsification performed with or without the White Star[○R] (Allergan) power control system. Methods: The study population comprised 26 individuals (37 eyes) with cataract but without any general or ocular complications. Subjects were recruited between No-vember 2001 and January 2002. According to the Emery-Little classification, 11 eyes were grade 2, 20 eyes were grade 3, and 6 eyes were grade 4. One group of patients (12 individuals, 18 eyes) underwent surgery with White Ster, the other group (14 individuals, 19 eyes) underwent surgery with the conventional program. Phacoemulsification in all cases was performed by the same surgeon. Main Outcome measures were operation time, total effective phaco time, average phaco power, irrigation solution volume, flare, value, corneal, thickness, and corneal endothelial cell loss. Results: Operation time was 19.9 ± 4.6 min with and 27.4 ± 8.8 min without the White Star. Conclusions: These results suggest that the White Star power control system improves phaco efficiency and reduces both surgical stress and damage to the corneal endothelium.
