飞秒激光辅助白内障联合TECNIS Symfony人工晶状体植入术后视觉质量的评价

目的：通过观察飞秒激光辅助的白内障手术联合TECNIS Symfony连续视程人工晶状体植入术后远中近全程视力、对比敏感度，主观满意度，综合评价TECNIS Symfony人工晶状体植入术后患者的视觉质量。

方法：收集我院目前已实施40例55眼飞秒激光辅助白内障联合TECNIS Symfony 连续视程人工晶状体植入术资料，检测术后3mo裸眼远视力(5 m)、中视力(67 cm)及近视力(40 cm)，绘制离焦曲线，根据多焦晶体满意度调查表并计算脱镜率。

结果：所有患者术中术后无严重并发症发生。术后3mo，所有患者人工晶状体位置居中，无明显偏位或倾斜。术后3mo， 5 m、67 cm、40 cm平均裸眼LogMAR视力分别为：-0.04±0.08， -0.17±0.22， 0.37±0.17。总体脱镜率95%。不同空间频率的对比敏感度较普通单焦非球面人工晶状体无明显下降。无中等或严重光学干扰现象发生。远中近各功能区满意度评分分别为9.0，9.0，7.0分。

结论：飞秒激光辅助的白内障手术联合TECNIS Symfony连续视程人工晶状体植入术后可获得满意的远中裸眼视力和基本满足日常生活的近视力，术后光学干扰少，脱镜率高，患者满意度高。

Clinical outcomes after femtosecond laser assisted cataract surgery with implantation of the tecnis symfony intraocular lens

AIM: To evaluate the clinical outcomes in terms of vision across distances(near, intermediate and far), contrast sensitivity and subjective patient satisfaction after femtosecond laser-assisted cataract surgery(FLACS)with implantation of an extended range of vision(ERV)intraocular lens(IOL).

METHODS: Forty patients(55 eyes)underwent bilateral or monocular FLACS with implantation of the ERV IOL Tecnis Symfony(Johnson & Johnson Vision)were enrolled. Uncorrected distance(UDVA), intermediate(UIVA)and near visual acuities(UNVA)were evaluated at 3mo after surgery, as well the defocus curve, contrast sensitivity, patient satisfaction and spectacle independence.

RESULTS:No severe complications occurred. All eyes showed a central position of the IOL in the capsular bag without tilting at 3mo after surgery. 3mo postoperative mean logMAR visual acuity at 5 m, 67 cm and 40 cm were -0.04 ±0.08, -0.17±0.22, 0.37±0.17, respectively. All patients obtained satisfactory UDVA and UIVA, as well as functional UNVA, meeting the needs of daily life. Spectacle independence rate was 94.55%. Contrast sensitivity results did not differ from those obtained with monofocal aspheric lenses. Likewise, no moderate and severe photic phenomena were reported. Mean patient satisfaction scores with distance, intermediate and near vision were 9.0, 9.0, and 7.0, respectively.

CONCLUSION: FLACS with implantation of the ERV IOL TECNIS Symfony provides a successful visual restoration at far, intermediate distance and a functional-range near vision acuity, with minimal level of disturbing photic phenomena, and high rates of spectacle independence and patient satisfaction.
