摘要目的:探讨Symfony新无级人工晶状体在临床的应用效果.方法:前瞻性临床研究.选择2016年8-12月在大庆油田总医院行白内障超声乳化联合Symfony新无级人工晶状体植入术患者74例(106眼),分别于术前,术后1 d、1周、1个月、3个月观察远、中、近距离视力(LogMAR),并进行对比敏感度、双离焦曲线及波前像差检查.手术前后数据比较采用重复测量方差分析.结果:所有患者术后1 d、1周、1个月、3个月时远、中、近距离视力均为0.3以上.术后远、中、近视力较术前显著提高,差异均有统计学意义(P<0.05);术后1周、1个月、3个月时+1.0～-2.5 D跨度视力均可达0.3以上;患者术前总像差、总低阶像差较术后1周、1个月、3个月时大,差异均有统计学意义(P<0.05).结论:Symfony新无级人工晶状体可为患者提供良好的视觉质量及连续视程.

abstractsObjective: To study the clinical utilization of the Symfony artificial lens, and to provide a theoretical basis for its widespread clinical application. Methods: This was a prospective study. Phacoemulsification combined with intraocular Symfony artificial lens implantation was performed on 74 cases of cataract (106 eyes) in the Oil Field General Hospital of Daqing from August to December, 2016. Measurements included far, middle, and near distance visual acuity (LogMAR), contrast sensitivity, defocus curve, and the wavefront aberration test before surgery, and 1 day, 1 week, 1 month, and 3 months postoperatively. Measured data were compared with repeated measurement analysis of variance. Results: After surgery, all patients had vision better than 0.3 in far, middle, and near distance at 1 day, 1 week, 1 month, and 3 months. Postoperative vision improved compared to preoperative levels and the difference was statistically significant (P<0.05). Visual acuity in the range of +1.0--2.5 D was better than 0.3 at 1 week, 1 month, and 3 months postoperatively. Total and lower order aberrations had decreased by 1 week, 1 month, and 3 months postoperatively compared to preoperative levels, and the differences were statistically significant (P<0.05). Conclusion: The Symfony artificial lens can provide patients with favorable visual quality and a continuous visual range.
