Clinical Evaluation of Low Contrast Visual Performance and Low Light Phenomena in Patients With Various Intraocular Lens Implants

NCT07213167 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 120

Last updated 2026-04-06

No results posted yet for this study

Summary

The goal of this clinical investigation is to evaluate visual acuity and contrast sensitivity in low lighting conditions using several different testing devices, and measure nighttime side effects of intraocular lens (IOL) implants after cataract surgery.

Researchers will compare the results for three different types of IOLs to see how each lens contributes to overall visual function, patient experience and satisfaction.

Participants will:

* Complete two different questionnaires about their current vision
* Undergo visual testing using several different devices
