PURPOSE
To quantitatively assess early postoperative endothelial damage caused by two phacoemulsification techniques and to ascertain the effect of differences in phacoemulsification time.
SETTING
Department of Ophthalmology, Umberto Hospital, Lugo, Italy.
METHODS
This prospective study evaluated 100 patients who had phacoemulsification using one of two techniques: phaco chop (n = 50) or four-quadrant, divide and conquer phacofracture (n = 50). The endothelium of both groups was analyzed preoperatively and 8 weeks postoperatively by specular microscopy.
RESULTS
Phaco chop led to significantly shorter phacoemulsification time and less endothelial damage. Mean equivalent phacoemulsification time was 25.53 seconds +/- 11.26 (SD) in the phaco chop group and 87.26 +/- 48.03 seconds in the phacofracture group. Endothelial cell loss was 4.72 +/- 1.2% and 13.80 +/- 4.3%, respectively.
CONCLUSION
The phaco chop technique led to shorter phacoemulsification time and less endothelial cell loss.
目的
定量评估两种超声乳化技术引起的术后早期内皮损伤，并确定超声乳化时间差异的影响。
设置
意大利卢戈翁贝托医院眼科。
方法
这项前瞻性研究评估了100例行超声乳化术的患者，他们采用两种技术之一：劈核法（n = 50）或象限劈裂、分而治之的晶状体粉碎术（n = 50）。两组患者术前及术后8周均通过镜面显微镜分析内皮情况。
结果
劈核法导致超声乳化时间显著缩短，内皮损伤更少。劈核法组平均等效超声乳化时间为25.53秒±11.26（标准差），晶状体粉碎术组为87.26±48.03秒。内皮细胞丢失率分别为4.72±1.2%和13.80±4.3%。
结论
劈核法技术导致超声乳化时间更短，内皮细胞丢失更少。
