摘　　要：目的:通过眼内散射光的检查,探讨人工晶状体屈光指数对白内障术后眩光值的影响。方法:采用病例对照研究,选取2013-08/2014-03期间就诊于中国医科大学眼科医院的最佳矫正视力BCVA≥0.5的年龄相关性白内障患者77例77眼,行白内障超声乳化吸除联合后房型非球面人工晶状体植入,所有的人工晶状体均为疏水性丙烯酸酯材料,随机分为3组;选用Tecnis ZCB00(屈光指数1.47)组22例22眼;选用Hoya PY60AD(屈光指数1.52)组24例24眼;选用Alcon SN60WF(屈光指数1.55)组31例31眼;测量患者术后的BCVA、瞳孔直径、散光度数等数据,C-QUANT测量散射光值。结果:各组的年龄、眼轴、BCVA、瞳孔大小、散光度数变化差异无统计学意义(P>0.05)。Tecnis组散射光值1.04±0.15;Hoya组散射光值1.19±0.14;IQ组散射光值1.14±0.18;眼内散射光值各组差异有统计学意义(F=5.352,P=0.007<0.05),BCVA与散射光值相关性分析无统计学意义(r=-0.133,P=0.124>0.05)。结论:选用高屈光指数人工晶状体的患者术后散射光值会更高。AIM： To investigate the influence of IOL refractive index（ RI） on measurement of straylight following cataract surgery.METHODS： In this case-control study,77 eyes of 77 age- related cataract patients who underwent cataract phacoemulsification with posterior chamber aspherical arylic IOL implantation surgery in the Eye Hospital of China Medical University from Aug 2013 to Mar 2014,with a best corrected visual acuity（ BCVA） of 0. 5 or better,were classified into 3 groups randomly using 3 types of IOL： Tecnis ZCB00 Group（ RI = 1. 47, 22 eyes of 22subjects）; Hoya PY60 AD Group（ RI = 1. 52,24 eyes of 24subjects）; Alcon SN60 WF or IQ Group（ RI = 1. 55,31 eyes of 31 subjects）. BCVA,pupil size,astigmatism,axial length,intraocular straylight were measured respectively.RESULTS： Age, axial length, BCVA, pupil size,astigmatism of the three groups were not significant difference（ P 〉 0. 05）. The straylight of Tecnis,Hoya,IQ group were 1. 04 ± 0. 15,1. 19 ± 0. 14,1. 14 ± 0. 18. Straylight levels had significant differences among three groups（ F= 5. 352,P = 0. 007 〈 0. 05）. There was no significant correlation between BCVA and straylight value（ r =- 0.133,P = 0. 124 〉 0. 05）.CONCLUSION： Patients chosen the higher RI IOL may have a higher straylight level after the surgery.
