目的:比较超声乳化术与小切口非超声乳化术治疗老年性白内障的临床疗效。
方法:白内障患者355例393眼分成A、B两组,其中A组180例193眼施行小切口非超声乳化白内障手术,B组175例200眼施行超声乳化白内障手术。术后观察视力、角膜散光、角膜内皮细胞计数情况。
结果:术后1d,患者视力恢复情况超声乳化手术组明显优于小切口非超声乳化手术组,但术后7d和30d两组无显著差异。术后7d,小切口非超声乳化组角膜散光度明显高于超声乳化组,但术后30d无显著性差异。对核硬度在Ⅳ~Ⅴ级的患者,超声乳化术后角膜内皮细胞计数少于小切口非超声乳化组,统计学分析有显著差异。
结论:应针对老年性白内障患者核硬度的具体情况,选择合适的手术方式进行治疗。

AIM:To investigate and compare the therapeutic effects of phacoemulsification and small-incision cataract surgery on senile cataract.
METHODS: Totally 355 cases(393 eyes)of senile cataract patients were divided into group A and group B by treatment modality. Group A with 180 cases(193 eyes)was treated with cataract surgery through a small-incision, and group B with 175 cases(200 eyes)was treated withphacoemulsification. Postoperative visual acuity, corneal astigmatism and the density of corneal endothelium were compared respectively.
RESULTS: One day postoperatively, the visual acuity inphacoemulsification group was much better than that in small-incision cataract surgery group, but there were no statistically significant differences at 7 and 30 days. The corneal astigmatism in patients with small-incision cataract surgery was higher than that of with phacoemulsification 7 days postoperatively, but there was no significant difference at 30 days. For those patients with Ⅳ-Ⅴ degree of nuclear hardness, the density of corneal endothelium in phacoemulsification group was less than that in small-incision cataract surgery group.
CONCLUSION: Suitable operative mode should be chosen according to the nuclear hardness of senile cataract patients.
