Objective: 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.
