目的 评价Acrysof Toric 人工晶状体的临床效果和旋转稳定性,以及角膜曲率测量方法对其矫正效果的影响.方法 收集浙江大学医学院附属第一医院眼科植入Toric IOL 的白内障患者20例23只眼.随机根据自动验光仪、角膜地形图和IOL Master测量的角膜曲率值计算植入相应的Acrysof Toric IOL,观察术后3个月裸眼视力(UCVA)、最佳矫正视力(BCVA)、角膜散光、总散光、人工晶状体旋转度,计算术源性散光(SIA),比较术前三种角膜曲率测量方法对散光矫正的影响.结果 术后患眼的UCVA为0.69±0.16,BCVA为0.83±0.15.患眼的总散光从术前的3.23D降至0.59D,下降了约82%.而术前后角膜曲率、角膜散光值差异无统计学意义.对术后总散光与目标残余散光的差值,三种角膜曲率测量方法之间差异无统计学意义.结论 Acrysof Toric 人工晶状体具有良好的散光矫正效果和旋转稳定性.自动角膜曲率测量方法对其散光矫正效果的影响不大.

Objective Objective To evaluate the clinical results and rotational stability of AcrySof Toric intraocular lens (IOLs), and the impact of three measurements of keratometry on the results of astigmatism correction. Methods This prospective study included 23 eyes of 20 patients having cataract surgery. The IOL was calculated randomly using the results of automatic refractor, corneal topography or IOL Mastor. Implantation of the toric IOL was performed. The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA), residual refractive cylinders, residual keratometry, and toric IOL axis were measured. And the differences of three measurements were analyzed. Results The UCVAs were 0.69±0.16 and BCVAs were 0.83±0.15 at 3 months follow-up. The mean refractive cylinder decreased significantly after surgery from 3.23 D to 0.59 D. The pre-surgical and post-surgical keratometry and corneal astigmatism showed no statistical difference. By analyzing the differrence from the post-surgical to the aimed residual astigmatism, there was no significant difference among these three measurements. Conclusions The results indicate that AcrySof toric IOL showed good clinical results and rotational stability. Automatic measurements of keratometry have no significant impact on its correction of astigmatism.
