目的：比较不同多焦点人工晶状体(MIOL)植入治疗白内障术后患者的视觉质量。

方法：选取2016-02/2017-06于本院行白内障超声乳化摘除联合MIOL植入手术的年龄相关性白内障患者78例78眼。根据植入MIOL的不同分为A、B、C组，各26例26眼。A组植入区域折射型MIOL SBL-3，B组植入阶梯渐进衍射型MIOL SN6AD1，C组植入全光学面衍射型MIOL Tecnis ZMB00。比较三组患者术后3mo的视力恢复情况、对比敏感度、离焦曲线、对比度视力以及视觉质量满意度。

结果：三组患者术后不良反应发生情况比较，差异无统计学意义(P>0.05)； 三组患者裸眼中视力、裸眼近视力、矫正远视力下的中视力、矫正远视力下的近视力的比较，差异均有统计学意义(P<0.05)，且A、B组均显著优于C组(P<0.05)。三组患者术后在明光、明光眩光下4种空间频率(3、6、12、18c/d)以及暗光、暗光眩光下3种空间频率(3、6、12c/d)的对比敏感度比较，差异均有统计学意义(P<0.05)，且A组患者均显著优于B、C组患者(P<0.05)。三组患者术后离焦曲线表明A、B组患者在-1.5、-2.0、-2.5D处视力高于C组患者(P<0.05)。三组患者术后对比度为20%、9%的对比度视力比较，差异均有统计学意义(P<0.05)，且A组显著优于B、C组患者(P<0.05)。三组患者术后视觉质量满意度比较，差异有统计学意义(P<0.05)，且A组显著优于B、C组(P<0.05)。

结论：区域折射型MIOL SBL-3不仅可提供较理想的远、近、中视力，还可提供更佳的对比敏感度及对比度视力，从而提高了患者对视觉质量的满意度。

METHODS:Totally 78 cases(78 eyes)of cataract patients who receiving phacoemulsification and implantation of different MIOL were enrolled from February 2016 to June 2017 in our hospital. According to the different type of implanted MIOL, the 78 cases(78 eyes)were divided Group A, B and C, each group was 26 cases(26 eyes). Patients in the Group A were implanted regional refraction MIOL SBL-3; patients in the Group B implanted step progressive diffraction MIOL SN6AD1; patients in the Group C implanted all-optical plane diffraction MIOL Tecnis ZMB00. The visual acuity, contrast sensitivity, defocus testing, contrast visual acuity and satisfaction of visual quality were compared in 3 groups at postoperative 3mo.

RESULTS: There was no statistically significant difference in postoperative adverse reactions between the three groups(P>0.05). There was statistical difference in uncorrected intermediate visual acuity, uncorrected near visual acuity, distance-corrected intermediate visual acuity and distance-corrected near visual acuity in 3 groups(P<0.05), and those in the Group C were significantly worse than those of Group A and B(P<0.05). There was statistical difference in contrast sensitivity at four spatial frequencies(3, 6, 12, 18c/d)in light and light glare and three spatial frequencies(3, 6, 12c/d)in dark and dark glare in 3 groups(P<0.05), and those in the Group A were significantly better than those of Group B and C(P<0.05). According to the defocus testing of 3 groups, the visual acuity at -1.5D, -2.0D and -2.5D in Group A and B was significantly higher than Group C(P<0.05). There was statistical difference in contrast visual acuity at 20% and 9% of contrast ratio in 3 groups(P<0.05), and those in Group A were significantly better than Group B and C(P<0.05). There was statistical difference in visual quality satisfaction in 3 groups(P<0.05), and that in the Group A was significantly better than that of Group B and C(P<0.05).

CONCLUSION:The region refraction MIOL SBL-3 not only could provide better distant, intermediate and near visual acuity, but also could provide better contrast sensitivity and contrast visual acuity, thereby greatly increase visual quality satisfaction.
