Evaluation of Visual Acuity and Patient Satisfaction With AT LISA TRI 839MP Intraocular Lenses

Carl Zeiss Meditec AG107 enrolled

Overview

The purpose of the study is to evaluate the far, intermediate and near visual acuities with a trifocal IOL.

After bilateral cataract surgery, monocular and binocular uncorrected (UCVA) and best distance corrected visual acuity (BCVA) will be measured at far (4m), intermediate (80 cm) and near (40 cm) distance as well as the subjective refraction. A patient questionnaire will be used to assess the patient satisfaction and spectacle independence.
