简要总结
The goal of this clinical trial is to compare the clinical outcomes of two extended depth-of-focus intraocular lens after cataract surgery. The randomized controlled trail will enroll 90 participants. The participants will be randomly assigned to implant Tecnis Synergy ZFR00 or Tecnis Symfony ZXR00 intraocular lens. Follow-up visit will be performed till 3 months postoperatively to compare the visual acuity, subjective manifest refraction, and visual quality between groups.

结局指标
主要结局
Visual acuity
时间窗: 1 day, 1 week, 1 month, 3 months postoperatively
Visual acuity will be assessed using the Standard Logarithmic Visual Acuity Chart. The results will be recorded in decimal and converted to logMAR and Snellen equivalent.
次要结局
- contrast sensitivity(3 months postoperatively)
- Visual quality(3 months postoperatively)
- defocus curve(3 months postoperatively)
