Clinical Evaluation of Extended Depth-of-focus Intraocular Lens in Refractive Cataract Surgery: a Randomized Controlled Trial

Clinical Evaluation of Extended Depth-of-focus Intraocular Lens in Refractive Cataract Surgery

Sponsor

Second Affiliated Hospital, School of Medicine, Zhejiang University

Enrollment

90 participants

Start Date

Dec 15, 2024

Study Type

INTERVENTIONAL

Conditions

Cataract

Summary

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.
