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.

RECRUITINGVisual acuity
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.
Time frame: 1 day, 1 week, 1 month, 3 months postoperatively
Visual quality
OPD-scan measurement. Higher-order aberration, tilt and decentration will be recorded.
Time frame: 3 months postoperatively
defocus curve
Best distance visual acuity varied from - 5.00 to + 2.00 D in steps of 0.50 D under photopic conditions was recorded.
Time frame: 3 months postoperatively
contrast sensitivity
Contrast sensitivity will be converted to logarithmic scale before analysis and referred to as log-contrast sensitivity.
Time frame: 3 months postoperatively
