方法：按照手术方式不同将本次收治的98例98眼单纯性老年白内障患者分组为对照组与治疗组，各49例49眼。对照组采用超声乳化手术治疗； 治疗组采用小切口非超声乳化术治疗。比较两组手术前后各时间段视力和角膜平均散光值、平均手术时间、并发症。

结果：两组患者术后3mo角膜散光值与术前比较无统计学意义(P>0.05)； 其他时段视力和角膜散光值明显优于术前，具有统计学意义(P<0.05)。两组患者手术时间和术后不同时间段平均视力及角膜散光值、并发症比较无统计学意义(P>0.05)。当晶状体核硬度为Ⅰ～Ⅲ级时，两组角膜内皮细胞计数比较无统计学意义(P>0.05)； 当晶状体核硬度为Ⅳ～Ⅴ级时，两组角膜内皮细胞计数比较具有统计学意义(P<0.05)。

结论：相比超声乳化手术来说，临床采用小切口非超声乳化手术治疗白内障效果与其相当，但临床需根据白内障患者核硬度实际情况来选择合适手术治疗，以提高临床疗效。

METHODS:The selected 98 patients(98 eyes)with age-related cataract were divided into treatment group and control group, according to different operative procedures, 49 patients(49 eyes)in each group. Patients in treatment group accepted phacoemulsification. Patients in control group were treated with small incision non-phacoemulsification cataract surgery. Visual acuity, average value of corneal, astigmatism before and after surgeries, operation time and complications were analyzed.

RESULTS:The difference on corneal astigmatism between the 2 groups at 3mo after surgeries was not statistically significant(P>0.05). The visual acuity and corneal astigmatism at other time points after surgeries were better that those before surgeries, and the differences were statistically significant(P<0.05). The operation time, visual acuity, corneal astigmatism and complications of the 2 groups at different time points after surgeries had no statistically significant differences(P>0.05). If the hardness of lens nucleus was at grade Ⅰ～Ⅲ, the corneal endothelial cells counting of the 2 groups had no statistically significant differences(P>0.05). If the hardness of lens nucleus was at grade Ⅳ～Ⅴ, the corneal endothelial cells counting of the 2 groups had statistically significant differences(P<0.05).

CONCLUSION:Compared with phacoemulsification, the clinical application of small incision non-phacoemulsification cataract surgery has equivalent effect. But to select the proper operation by the hardness of lens nucleus can improve the clinical efficacy.
