目的：比较接受双眼Symfony连续视程人工晶状体(intraocular lens，IOL)植入与接受单眼Symfony连续视程IOL植入而另一眼非球面单焦点IOL植入患者术后的生活质量。

方法：采用以人群为基础的横断面研究。以美国国家眼科研究所研制开发的视功能调查问卷(the National Eye Institute Visual Functioning Questionnaire-25，NEI VFQ-25)对研究对象的术后视功能相关生活质量(vision-related quality of life，vision-related QoL)进行评价。收集2017-03/2018-03行白内障超声乳化吸除联合IOL植入术的患者30例60眼，按照植入IOL类型分为两组，双眼植入TECNIS Symfony连续视程人工晶状体(ZXR00)为双眼组(18例36眼)，一眼植入TECNIS Symfony连续视程人工晶状体(ZXR00)，另一眼植入非球面单焦点IOL(PCB00)为单眼组(12例24眼)。术后3～6mo进行随访，主要观察指标为双眼远、中、近裸眼视力和生活质量调查问卷。

结果：双眼组和单眼组术后双眼裸眼远、中、近视力比较，差异无统计学意义(P>0.05)。两组患者术后NEI VFQ-25问卷总评分(88.95±4.01 vs 88.99±4.22分)比较，差异无统计学意义(t=-0.025，P=0.980)。12个维度的评分结果对比显示，两组患者术后与视觉相关的各个方面生活质量差异均无统计学意义(P>0.05)。

结论：双眼植入ZXR00或一眼植入ZXR00，另一眼植入PCB00的患者均具有良好的双眼全程视力。两组患者的术后生活质量无差异。对一眼已行单焦点IOL植入的患者或一眼不适合装多焦点人工晶状体的患者，可行另一眼Symfony连续视程IOL植入以满足患者脱镜需求。

METHODS: A population-based cross-sectional study was performed. The visual function-related quality of life(QoL)was evaluated with the National Eye Institute Visual Functioning Questionnaire-25(NEI VFQ-25)which was developed by the National Eye Institute. Thirty patients(60 eyes)who underwent phacoemulsification combined with IOL implantation from March 2017 to March 2018 were divided into two groups according to the type of implanted IOL. For bilateral group(36 eyes in 18 cases), patients accepted TECNIS Symfony(ZXR00, AMO)in both eyes. For unilateral group(24 eyes in 12 cases), patients accepted TECNIS Symfony(ZXR00, AMO)in one eye and an aspherical monofocal IOL(PCB00,AMO)in the other eye. Follow-up was performed 3-6mo after surgery. Postoperative binocular uncorrected distant, intermediate and near visual acuity(bUCDVA, bUCIVA and bUCNVA)were compared and the quality of life was evaluated for every patient.

RESULTS:There were no statistical differences in bUCDVA, bUCIVA and bUCNVA between two groups(P>0.05). There was no significant difference in composite scores of the NEI VFQ-25 questionnaire between bilateral group and unilateral group(88.95±4.01 vs 88.99±4.22, t=-0.025, P=0.980). A comparison of the 12 scales acquired from the questionnaire showed that there were no statistical differences in visual function-related quality of life in the two groups(P>0.05).

CONCLUSION:Compared with bilateral implantation of ZXR00, the patients with the implantation of ZXR00 in one eye and PCB00 in the other eye share the excellent binocular uncorrected distant, intermediate and near visual acuity and postoperative quality of life. For patients who have undergone monofocal IOL implantation in one eye or whose one eye is not suitable for multifocal IOLs, unilateral implantation of Symfony continuous-vision IOL is feasible to meet patients' need for spectacle independency.
