Official title

Clinical Evaluation of Low Contrast Defocus Curves, Low Light Photic Phenomena, and Dysphotopsia Profiles in Pseudophakic Patients

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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
