目的：比较连续视程(Tecnis Symfony)人工晶状体(IOL)和区域折射型(Lentis Comfort LS-313 MF15)IOL植入术后患者的视觉质量。

方法：临床前瞻性研究。收集2021-01/12在我院行白内障超声乳化联合IOL植入术的白内障患者267例(305眼)，按植入IOL类型分为Symfony组(A组，160眼)和MF15组(B组，145眼)，观察两组患者术后3mo裸眼远视力(uncorrected distance visual acuity， UDVA)(5m)、裸眼中视力(uncorrected intermediate visual acuity， UIVA)(80cm)、裸眼近视力(uncorrected near visual acuity， UNVA)(40cm)，离焦曲线，调制传递函数(MTF)和高阶相差(HOAs)，包括彗差、球差、三叶草差，进行视觉质量问卷调查(Quality of Vision questionnaire，QoV)。

结果：两组患者术前各参数差异均无统计学意义(P>0.05)。A组和B组UDVA和UNVA差异无统计学意义(P>0.05)； A组的UIVA高于B组(P<0.05)； A组的MTF值在各个空间频率下均高于B组，差异具有统计学意义(P<0.05)； A组的HOAs低于B组(P<0.05)； 术后3mo绘制离焦曲线显示0D处两组视力相似，-0.5D～-2.5D处A组视力优于B组，且在-1.0D和-2.0D处差异有统计学意义(P<0.05)； A组的Qov分数高于B组(P<0.05)； A组出现光晕，星爆等不良视觉干扰现象的频率要高于B组。

结论：MF15和Symfony均提供了稳定的远，近距离视力； 与MF15相比，Symfony IOL具有较好的中距离视力，较高的对比敏感度以及较低的HOAs； 与Symfony相比，MF15人工晶状具有更少的术后不良视觉干扰现象(光晕，星芒等)。

METHODS: A prospective clinical study. Collecting 267 cataract patients(305 eyes)who underwent phacoemulsification combined with IOL implantation surgery in our hospital from January 2021 to December 2021,they were divided into the Symfony group(group A, 160 eyes)and MF15 group(group B, 145 eyes)according to the types of implanted IOL. Postoperative visual acuity were observed at 3mo and included uncorrected distance visual acuity(UDVA, 5m), uncorrected intermediate visual acuity(UIVA, 80 cm), uncorrected near visual acuity(UNVA, 40cm), defocus curve, modulation transfer function(MTF)and high-order aberrations(HOAs), including coma, spherical aberration and trefoil aberration, and conducted the Quality of Vision(QoV)questionnaire.

RESULTS: There were no significant differences in the preoperative parameters in both groups(P>0.05). There was no significant difference between the UDVA and UNVA in groups A and B(P>0.05); The UIVA was higher in group A than in group B(P<0.05); The MTF value in group A was higher than group B at all spatial frequency, and the difference was statistical significant(P<0.05); The HOAs in group A was lower than that in group B(P<0.05); Defocus curves were plotted 3mo after the operation suggest that the visual acuity of the two groups was similar at 0D, and the visual acuity of the groups A was better than group B from -0.5D to -2.5D, and there was a statistically significant difference at -1.0D and -2.0D(P<0.05). The QoV score in group A was significantly higher than that in group B(P<0.05). The frequency of bad visual interference such as halo and starburst was higher in group A than in group B.

CONCLUSION: Both the MF15 and Symfony can provide stable distance and near visual acuity. Compared with MF15, Symfony had better intermediate visual acuity, higher contrast sensitivity and lower HOAs. Compared with Symfony, MF15 IOL had less postoperative bad visual interference symptoms(halo, starburst, etc).
