초음파유화장치의 화이트스타 방식과 연속방식의 수술 결과 비교

Comparison of Surgical Results between WhiteStar Mode and Continuous Mode in the Phacoemulsification Unit

Purpose: To compare the results of cataract surgery between continuous mode and WhiteStar mode the latter is known to induce less heat production in the anterior chamber Methods: The patients were recruited prospectively since May 2003. They were consecutively assigned to the continuous mode group and the WhiteStar mode group according to preoperative lens color grading in order to equally distribute the lens color grading in both groups. Ultrasound time, operating time, and loss of endothelial cells were evaluated. Results: There was a positive correlation between lens color and ultrasound time and between lens color and operating time (p<0.01). There was no significant difference between the two groups in ultrasound time, operating time or loss of endothelial cells. Conclusions: There was no remarkable advantage in cataract surgery using WhiteStar mode compared with using conventional continuous mode.
