目的 探讨Acrysof Toric人工晶体治疗合并角膜散光老年性白内障的疗效.方法 选取术前存在角膜散光的老年性白内障患者31例(34眼).采用白内障超声乳化摘除术植入Acrysof Toric人工晶体,分别于术前、术后首日、术后1周、术后1个月、术后3个月时检测患者裸眼视力、最佳矫正视力、角膜曲率,观察Toric人工晶体轴向位置和转动度数.结果 术前患眼最佳矫正视力为0. 1~0. 5,术后3个月时31例患眼裸眼视力>0. 5;26例患眼裸眼视力≥0. 8;32例患眼最佳矫正视力≥0. 8.术前角膜散光度值、预期残余散光度值、术后3个月时残余散光均值三者间差异具有统计学意义(F=9. 251,P<0. 05).术后3 个月残余散光均值明显低于术前角膜散光值,差异具有显著统计学意义(t=17. 264,P<0. 01);术后残余散光值与预期值之间差异无统计学意义(t=0. 517, P>0. 05).术后首日9眼偏离了预定轴位,平均偏差为4. 02°±0. 65°,其中4眼偏差大于10°.术后3个月时与术后首日相比,人工晶体旋转均值为2. 48°±1. 96°,其中仅1眼旋转幅度>10°,余下的33眼旋转幅度均<5°.结论植入Acrysof Toric人工晶体可有效提升合并角膜散光老年性白内障患者的视力,矫正术前角膜散光,且稳定性较佳.

Objective To investigate the clinical effect of Acrysof Toric intraocular lens on the treatment of senile cataract combined with corneal astigmatism. Method A total of 31 senile cataract patients(34 eyes) with corneal astigmatism were selected. AcrySof Toric intraocular lens was implanted by phacoemulsification. Before the operation,and on the 1st day,1st week,1st month and 3th month after the operation,the uncorrected visual acuity,best corrected visual acuity and corneal curvature of the patients were detected,and the axial position and rotation degree of Toric intraocular lens were also observed. Results The preoperative best corrected visual acuities of the patients were from 0. 1 to 0. 5. At the 3th month post operation,the naked visual acuities of 31 cases were more than 0. 5,26 cases of bare eye sight were more than or equal to 0. 8,the best corrected visual acuity of 32 cases were more than or equal to 0. 8. The differences among preoperative corneal astigmatism, expected residual astigmatism,and residual astigmatism after 3 months were statistically significant ( F=9. 251, P<0. 05). After 3 months,the residual astigmatism average mean was significantly lower than the preoperative corneal astigmatism (t=17. 264,P<0. 01). The difference between postoperative residual astigmatism value and the expected value was not statistically significant (t=0. 517,P>0. 05). On the first day after operation,9 eyes deviated from the predetermined axis with average deviation of 4 . 02 ° ± 0 . 65 ° , and the deviation of 4 eyes were more than 10°. Compared with the first day after operation,at the 3th month,the average value of artificial crystal rotation was 2. 48°±1. 96°,with only 1 rotation more than 10°,and the remaining 33 cases were all less than 5°. Conclusion Intraocular lens implantation of Acrysof Toric intraocular lens can effectively improve the visual acuity,corneal astigmatism and the stability of corneal astigmatism in the patients with senile cataract.
