目的：分析飞秒激光辅助白内障手术(FLACS)在硬核白内障患者中的应用效果。

方法：回顾性分析我院FLACS(观察组)和传统超声乳化术(对照组)治疗的硬核白内障患者各42例42眼的临床资料。记录两组患者手术情况及术后恢复情况。

结果：观察组平均超声功率、实际及有效超声乳化时间、术后3d角膜水肿程度均低于对照组(P<0.05)。两组术后矫正远视力(CDVA)、裸眼远视力(UCDVA)和角膜内皮细胞丢失率变化情况均为：术后3d>术后1wk>术后1mo，而观察组变化幅度大于对照组(P<0.05)。观察组术后各时间点角膜内皮细胞密度高于对照组(P<0.05)。

结论：FLACS治疗硬核白内障效果显著。

METHODS: The clinical data of each 42 cases(eyes)in patients with hard nuclear cataract who underwent FLACS(observation group)and traditional phacoemulsification(control group)were retrospectively analyzed. The operation conditions and postoperative recovery were recorded in the two groups.

RESULTS: The mean ultrasound power, actual phacoemulsification time and effective phacoemulsification time and corneal edema degree at 3d after operation in observation group were lower than those in control group(P<0.05). The changes of postoperative corrected distance visual acuity(CDVA), uncorrected distance visual acuity(UCDVA)and corneal endothelial cell loss rate showed 3d after operation>1wk after operation>1mo after operation, and the changes in observation group were greater than those in control group(P<0.05). The corneal endothelial cell density in observation group at each time point after operation was higher than that in control group(P<0.05).

CONCLUSION: FLACS has significant effects on hard nuclear cataract.
