Study Summary

This trial aims to compare two types of lenses used during cataract surgery. They will test how well these lenses improve vision in low light conditions. Participants will be asked to read a chart at different

Who is the study for?
This trial is for adults aged 50 or older who are having routine cataract surgery in both eyes and expect good vision afterward. They must be able to follow the study's schedule and procedures, have no severe eye conditions, uncontrolled diabetes, history of certain eye surgeries or diseases that could affect their zonules or visual performance.Check my eligibility
What is being tested?
The study compares two types of intraocular lenses (IOLs), Symfony and Vivity, used in cataract surgery. It specifically looks at how well patients can see with each lens under dim light by reading a chart at various distances.See study design
What are the potential side effects?
While specific side effects aren't listed here, typical risks associated with IOL implantation include inflammation, infection risk increase after surgery, potential for impaired vision due to lens dislocation or incorrect lens power.

Trial Design

2Treatment groups
Active Control
Group I: Symfony IOLActive Control1 Intervention
The Symfony IOL is a lens designed to provide high quality vision up tp 26 inches reducing the need for glasses after routine cataract surgery in patients with or without astigmatism.
Group II: Vivity IOLActive Control1 Intervention
The Vivity IOL is a lens that provides extended range of vision ranging from distance to near reducing the need for glasses after routine cataract surgery in patients with or without astigmatism.
