目的 对比植入不同球面像差的IOL后,不同全眼的球面像差眼的视觉质量.方法 晶状体超声乳化人工晶状体植入术55例（63只眼）,术中均根据患者角膜球面像差而植入不同球面像差的IOL,依据术后全眼的球面像差值的不同分为3组：A组,术后全眼的球面像差为（-0.20±0.05）μm,B组为（0.00±0.03）μm,C组为（＋0.10±0.03）μm.比较3组术后3个月的裸眼视力（UCVA）、最佳矫正视力（BCVA）、全眼总高阶像差、调制传递函数（MTF）值和患者满意度调查等.结果 术后3个月3组之间UCVA、BCVA差异均无统计学意义（H=4.418,H=0.050;P=0.110,P=0.975）.3组间的全眼总高阶像差比较,差异无统计学意义（H=2.637,P=0.268）.术后3组的MTF值比较,差异有统计学意义（P=0.000）.患者满意度3组差异有统计学意义（F=20.845,P=0.000）.结论 根据角膜球面像差个性化植入IOL,使术后全眼的球面像差为＋0.1 μm时,视觉质量较好,满意度较高.
Objective To compare the visual quality of different total eye spherical aberration after different spherical aberration IOL implantation.Methods Sixty-three eyes of 55 cases underwent phacoemulsification and IOL implantation.All patients were implanted different spherical aberration IOL based on corneal spherical aberration.According to the different postoperative total eye spherical aberration,patients were divided into 3 groups.Group A, postoperative total spherical aberration was spherical aberration,patients were divided into 3 groups.Group A, postoperative total spherical aberration was （-0.2±0.05）μm, group B was （0±0.03）μm and group C was（＋0.1±0.03）μm.Three months after surgery, uncorrected visual acuity, best corrected visual acuity,total high order aberration,modulation transfer function（MTF） and satisfaction of the three groups were compared.Results The differences in postoperative uncorrected visual acuity and the best corrected visual acuity between the three groups were not statistically significant（H=.418,H=0.050;P=0.110,P=0.975）.The difference in high order aberration（HOA） was not statistically significant among the three groups（H=2.637,P=0.268）.The difference in MTF was statistically significant among the three groups （P=0.000）.The difference in satisfaction was statistically significant among the three groups（F=20.845,P=0.000）.Conclusion According to the corneal spherical aberration personalized implanted IOL, making total eye spherical aberration to ＋0.1 μm, the surgery may obtain better postoperative visual quality and higher satisfaction.
