PURPOSE
To evaluate the safety and usefulness of phaco-chop cataract extraction.
SETTING
A university-associated, multispecialty ophthalmology practice.
METHODS
Fifty-three patients in a university-associated ophthalmology practice had cataract extraction, 32 by the phaco-chop technique and 21 by four-quadrant divide and conquer phacoemulsification. Phacoemulsification energy and complication rates were compared.
RESULTS
Mean phacoemulsification energy was significantly lower in the phaco-chop group (mean 782 J +/- 446 [SD]) than in the divide and conquer group (mean 3264 +/- 1218 J)(P < .00001). No complications occurred in either group.
CONCLUSION
The phaco-chop technique provided safe, effective cataract extraction with significantly less energy than that required for divide and conquer phacoemulsification.
目的
评估超声乳化劈核白内障摘除术的安全性和有效性。
地点
一所大学附属的多专科眼科诊所。
方法
一所大学附属眼科诊所的53例患者接受了白内障摘除术，其中32例采用超声乳化劈核技术，21例采用象限分离式超声乳化术。比较了超声乳化能量和并发症发生率。
结果
超声乳化劈核组的平均超声乳化能量（平均782 J±446[标准差]）显著低于分离式超声乳化组（平均3264±1218 J）（P<.00001）。两组均未发生并发症。
结论
超声乳化劈核技术提供了安全、有效的白内障摘除术，所需能量明显低于分离式超声乳化术。
