About This Trial
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 exp…
