Acrysof Toric人工晶体治疗合并角膜散光老年性白内障的疗效观察
Therapeutic Effect of Toric Acrysof Intraocular Lens on the Treatment of Senile Cataract Combined with Corneal Astigmatism
摘要
Abstract
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.关键词
